Cisco Security Advisory: Cisco IOS Software Network Address
Translation Vulnerabilities
Advisory ID: cisco-sa-20100922-nat
http://www.cisco.com/warp/public/707/cisco-sa-20100922-nat.shtml
Revision 1.0
For Public Release 2010 September 22 1600 UTC (GMT)
- ---------------------------------------------------------------------
Summary
=======
The Cisco IOS Software Network Address Translation functionality
contains three denial of service (DoS) vulnerabilities. The first
vulnerability is in the translation of Session Initiation Protocol
(SIP) packets, the second vulnerability in the translation of H.323
packets and the third vulnerability is in the translation of H.225.0
call signaling for H.323 packets.
Cisco has released free software updates that address these
vulnerabilities.
This advisory is posted at
http://www.cisco.com/warp/public/707/cisco-sa-20100922-nat.shtml
Note: The September 22, 2010, Cisco IOS Software Security Advisory
bundled publication includes six Cisco Security Advisories. Five of
the advisories address vulnerabilities in Cisco IOS Software, and one
advisory addresses vulnerabilities in Cisco Unified Communications
Manager. Each advisory lists the releases that correct the
vulnerability or vulnerabilities detailed in the advisory. The table
at the following URL lists releases that correct all Cisco IOS
Software vulnerabilities that have been published on September 22,
2010, or earlier:
http://www.cisco.com/warp/public/707/cisco-sa-20100922-bundle.shtml
Individual publication links are in "Cisco Event Response: Semiannual
Cisco IOS Software Security Advisory Bundled Publication" at the
following link:
http://www.cisco.com/web/about/security/intelligence/Cisco_ERP_sep10.html
Affected Products
=================
Vulnerable Products
+------------------
Cisco devices running Cisco IOS Software that are configured for NAT
and that support NAT for SIP, H.323, or H.225.0 call signaling for
H.323 packets are affected.
To verify whether NAT is enabled on a Cisco IOS device log in to the
device and issue the show ip nat statistics command. The following
example shows a device that is configured with NAT:
Router#show ip nat statistics
Total translations: 2 (0 static, 2 dynamic; 0 extended)
Outside interfaces: Serial0
Inside interfaces: Ethernet1
Hits: 135 Misses: 5
Expired translations: 2
Dynamic mappings:
-- Inside Source
access-list 1 pool mypool refcount 2
pool mypool: netmask 255.255.255.0
start 192.168.10.1 end 192.168.10.254
type generic, total addresses 14, allocated 2 (14%), misses 0
Alternatively, administrators can use the show running-config |
include ip nat command to verify if NAT has been enabled on the
router interfaces.
For NAT to be enabled in a router either the ip nat inside and ip nat
outside commands must be present in different interfaces or, in the
case of NAT Virtual Interface, if the ip nat enable interface command
is present.
In order to determine the software that runs on a Cisco IOS product,
log in to the device and issue the show version command to display
the system banner. Cisco IOS software identifies itself as
"Internetwork Operating System Software" or simply "IOS." On the next
line of output, the image name displays between parentheses, followed
by "Version" and the Cisco IOS release name. Other Cisco devices do
not have the show version command or give different output.
The following example shows output from a device that runs an IOS
image:
Router> show version
Cisco IOS Software, C3900 Software (C3900-UNIVERSALK9-M), Version 15.0(1)M1, RELEASE SOFTWARE (fc1)

<More output removed for brevity>
Products Confirmed Not Vulnerable
+--------------------------------
Cisco IOS devices not explicitly configured for NAT are not
vulnerable.
Cisco IOS XE Software is not affected by these vulnerabilities.
Cisco IOS XR Software is not affected by these vulnerabilities.
No other Cisco products are currently known to be affected by these
vulnerabilities.
Details
=======
The three vulnerabilities are triggered by transit traffic that needs
to be processed by the NAT feature. Each vulnerability is independent
of each other.
NAT for SIP DoS Vulnerability
+----------------------------
SIP is a popular signaling protocol that is used to manage voice and
video calls across IP networks such as the Internet. SIP is
responsible for handling all aspects of call setup and termination.
Voice and video are the most popular types of sessions that SIP
handles, but the protocol has the flexibility to accommodate other
applications that require call setup and termination.
NAT for SIP translates packets using UDP (port 5060) or TCP (port
5060) as the underlying transport protocol. The NAT for SIP DoS
vulnerability can be exploited only with the use of UDP port 5060
packets.
This vulnerability is documented in Cisco bug ID CSCtf17624
and has been assigned Common Vulnerabilities and Exposures (CVE)
ID CVE-2010-2831.
NAT for H.323 DoS Vulnerability
+------------------------------
H.323 is the International Telecommunication Union (ITU) standard for
real-time multimedia communications and conferencing over
packet-based (IP) networks.
NAT for H.323 translates packets on TCP port 1720. There is a DoS
vulnerability in the NAT procession of H.323 packets. The
vulnerability does not require the completion of a TCP three-way
handshake.
This vulnerability is documented in Cisco bug ID CSCtf91428
and has been assigned Common Vulnerabilities and Exposures (CVE) IDs
CVE-2010-2832.
NAT for H.225.0 DoS vulnerability
+--------------------------------
H.323 is the ITU standard for real-time multimedia communications and
conferencing over packet-based (IP) networks. A subset of the H.323
standard is H.225.0, a standard used for call signaling protocols and
media stream packetization over IP networks.
NAT for H.225.0 translates packets on TCP port 1720. There is a DoS
vulnerability in the NAT translation of H.225.0 call signaling for
H.323 packets.
This vulnerability is documented in Cisco bug ID CSCtd86472
and has been assigned Common Vulnerabilities and Exposures (CVE) IDs
CVE-2010-2833.
Vulnerability Scoring Details
=============================
Cisco has provided scores for the vulnerabilities in this advisory
based on the Common Vulnerability Scoring System (CVSS). The CVSS
scoring in this Security Advisory is done in accordance with CVSS
version 2.0.
CVSS is a standards-based scoring method that conveys vulnerability
severity and helps determine urgency and priority of response.
Cisco has provided a base and temporal score. Customers can then
compute environmental scores to assist in determining the impact of
the vulnerability in individual networks.
Cisco has provided an FAQ to answer additional questions regarding
CVSS at:
http://www.cisco.com/web/about/security/intelligence/cvss-qandas.html
Cisco has also provided a CVSS calculator to help compute the
environmental impact for individual networks at:
http://intellishield.cisco.com/security/alertmanager/cvss

======
Successful exploitation of any of the vulnerabilities described in
this document may cause the affected device to reload. Repeated
exploitation will result in an extended denial of service (DoS)
condition.
Software Versions and Fixes
===========================
When considering software upgrades, also consult
http://www.cisco.com/go/psirt and any subsequent advisories to
determine exposure and a complete upgrade solution.
In all cases, customers should exercise caution to be certain the
devices to be upgraded contain sufficient memory and that current
hardware and software configurations will continue to be supported
properly by the new release. If the information is not clear, contact
the Cisco Technical Assistance Center (TAC) or your contracted
maintenance provider for assistance.
Each row of the following Cisco IOS Software table corresponds to a
Cisco IOS Software train. If a particular train is vulnerable, the
earliest releases that contain the fix are listed in the First Fixed
Release For This Advisory column. The First Fixed Release for All
Advisories in the September 2010 Bundle Publication column lists the
earliest possible releases that correct all the published
vulnerabilities in the Cisco IOS Software Security Advisory bundled
publication. Cisco recommends upgrading to the latest available
release, where possible.

Cisco IOS SSL VPN Vulnerability
Advisory ID: cisco-sa-20100922-sslvpn
http://www.cisco.com/warp/public/707/cisco-sa-20100922-sslvpn.shtml
Revision 1.0
For Public Release 2010 September 22 1600 UTC (GMT)
- ---------------------------------------------------------------------
Summary
=======
Cisco IOS Software contains a vulnerability when the Cisco IOS SSL
VPN feature is configured with an HTTP redirect. Exploitation could
allow a remote, unauthenticated user to cause a memory leak on the
affected devices, that could result in a memory exhaustion condition
that may cause device reloads, the inability to service new TCP
connections, and other denial of service (DoS) conditions.
Cisco has released free software updates that address this
vulnerability. There is a workaround to mitigate this vulnerability.
This advisory is posted at
http://www.cisco.com/warp/public/707/cisco-sa-20100922-sslvpn.shtml
Note: The September 22, 2010, Cisco IOS Software Security Advisory
bundled publication includes six Cisco Security Advisories. Five of
the advisories address vulnerabilities in Cisco IOS Software, and one
advisory addresses vulnerabilities in Cisco Unified Communications
Manager. Each advisory lists the releases that correct the
vulnerability or vulnerabilities detailed in the advisory. The table
at the following URL lists releases that correct all Cisco IOS
Software vulnerabilities that have been published on September 22,
2010, or earlier:
http://www.cisco.com/warp/public/707/cisco-sa-20100922-bundle.shtml

Cisco IOS Software Security Advisory Bundled Publication" at the
following link:
http://www.cisco.com/web/about/security/intelligence/Cisco_ERP_sep10.html
Affected Products
=================
Vulnerable Products
+------------------
Devices running affected versions of Cisco IOS Software are
vulnerable if configured with SSL VPN and HTTP port redirection.
The following methods may be used to confirm if the device is
configured for Cisco IOS SSL VPNs and is vulnerable:
If the output from show running-config | include webvpn contains
"webvpn gateway <word>" then the device is supporting the Cisco IOS
SSL VPN feature. A device is vulnerable if it has the inservice
command in at least one of the "webvpn gateway" sections and is
configured for HTTP port redirection. The following example shows a
vulnerable device configured with Cisco IOS SSL VPN:
Router#show running | section webvpn
webvpn gateway Gateway
ip address 10.1.1.1 port 443
http-redirect port 80
ssl trustpoint Gateway-TP
inservice
!
Router#
A device that supports the Cisco IOS SSL VPN is not vulnerable if
"webvpn gateway" is not configured.
To determine the Cisco IOS Software release that is running on a
Cisco product, administrators can log in to the device and issue the
show version command to display the system banner. The system banner
confirms that the device is running Cisco IOS Software by displaying
text similar to "Cisco Internetwork Operating System Software" or
"Cisco IOS Software." The image name displays in parentheses,
followed by "Version" and the Cisco IOS Software release name. Other
Cisco devices do not have the show version command or may provide
different output.
The following example identifies a Cisco product that is running
Cisco IOS Software Release 12.4(20)T with an installed image name of
C2800NM-ADVSECURITYK9-M:
Router#show version
Cisco IOS Software, 2800 Software (C2800NM-ADVSECURITYK9-M), Version 12.4(20)T, RELEASE SOFTWARE (fc3)

conventions is available in "White Paper: Cisco IOS Reference Guide"
at the following link: http://www.cisco.com/warp/public/620/1.html
Products Confirmed Not Vulnerable
+--------------------------------
The following products are not affected by this vulnerability:
* Cisco ASA 5500 Series Adaptive Security Appliances
* Cisco IOS XR Software
* Cisco IOS XE Software
No other Cisco products are currently known to be affected by this
vulnerability.
Details
=======
The Cisco IOS SSL VPN feature provides remote access to enterprise
sites to users anywhere on the Internet. The SSL VPN provides users
with secure access to specific enterprise applications, such as
e-mail and web browsing, without requiring them to have VPN client
software installed on their end-user devices.
Further information about Cisco IOS SSL VPN is available in the
"Cisco IOS Software Release 12.4T SSL VPN feature guide" at the
following link:
http://www.cisco.com/en/US/docs/ios/12_4t/12_4t11/htwebvpn.html leavingcisco.com
A device configured for SSL VPN with HTTP port redirection may leak
transmission control blocks (TCBs) when processing an abnormally
disconnected SSL session. Continued exploitation may cause the device
to deplete memory resources, which could result in device reloads,
the inability to service new TCP connections, and other DoS
conditions. Authentication is not required to exploit this
vulnerability.
A complete TCP 3-way handshake is required to exploit this
vulnerability. The memory leak can be detected by running the command
show tcp brief as shown in the following example:
Router#show tcp brief
TCB Local Address Foreign Address (state)

Workarounds
===========
Disabling HTTP redirection for SSL VPN connections can be used as a
workaround for this vulnerability. HTTP redirection for SSL VPN
connections is disabled by executing the command no http-redirect
port in webvpn gateway configuration mode.
In addition, manually clearing the hung TCBs with the command clear
tcp tcb * will transition the TCBs into a CLOSED state. After a time
they will clear the CLOSED state and the memory will be released.
Note: Clearing the TCB will clear both legitimate and hung
connections, including remote connections to the device such as
Telnet and SSH connections.
The Cisco Applied Mitigation Bulletin (AMB) "Identifying and
Mitigating Exploitation of the TCP State Manipulation Denial of
Service Vulnerabilities in Multiple Cisco Products", available at
http://www.cisco.com/warp/public/707/cisco-amb-20090908-tcp24.shtml,
contains two mitigations (EEM scripts and SNMP) that can be used to
detect and clear hung TCP connections.
Embedded Event Manager (EEM)
+---------------------------
A Cisco IOS Embedded Event Manager (EEM) policy that is based on Tool
Command Language (Tcl) can be used on vulnerable Cisco IOS devices to
identify and detect a hung, extended, or indefinite TCP connection
that is caused by this vulnerability. The policy allows
administrators to monitor TCP connections on a Cisco IOS device. When
Cisco IOS EEM detects potential exploitation of this vulnerability,
the policy can trigger a response by sending a syslog message or a
Simple Network Management Protocol (SNMP) trap to clear the TCP
connection. The example policy provided in this document is based on
a Tcl script that monitors and parses the output from two commands at
defined intervals, produces a syslog message when the monitor
threshold reaches its configured value, and can reset the TCP
connection.
The Tcl script is available for download at the "Cisco Beyond:
Embedded Event Manager (EEM) Scripting Community" at the following
link: http://forums.cisco.com/eforum/servlet/EEM?page=eem&fn=script&scriptId=2041
A sample device configuration is provided below.
!
!-- Location where the Tcl script will be stored
!
event manager directory user policy disk0:/eem
!
!-- Define variable and set the monitoring interval
!-- as an integer (expressed in seconds)
!
event manager environment EEM_MONITOR_INTERVAL 60
!
!-- Define variable and set the threshold value as

services, issue the show process cpu | include H323 command, as shown
in this example:
Router# show process cpu | include H323
249 16000 3 5333 0.00% 0.00% 0.00% 0 CCH323_CT
250 0 1 0 0.00% 0.00% 0.00% 0 CCH323_DNS
Router#
In the previous example the processes CCH323_CT and CCH323_DNS are
running on the device; therefore, the device is listening to H.323
messages. The device is vulnerable if any of these processes (or
similar) are active.
Note: Creating a dial peer by issuing the dial-peer voice command
will start the H.323 processes, which causes the Cisco IOS device to
process H.323 messages.
To determine the Cisco IOS Software release that is running on a
Cisco product, administrators can log in to the device and issue the
show version command to display the system banner. The system banner
confirms that the device is running Cisco IOS Software by displaying
text similar to "Cisco Internetwork Operating System Software" or
"Cisco IOS Software." The image name displays in parentheses,
followed by "Version" and the Cisco IOS Software release name. Other
Cisco devices do not have the show version command or may provide
different output.
The following example identifies a Cisco product that is running
Cisco IOS Software Release 12.3(26) with an installed image name of
C2500-IS-L:
Router# show version
Cisco Internetwork Operating System Software
IOS (tm) 2500 Software (C2500-IS-L), Version 12.3(26), RELEASE SOFTWARE (fc2)

Products Confirmed Not Vulnerable
+--------------------------------
Cisco IOS XR Software is not affected by these vulnerabilities.
No other Cisco products are currently known to be affected by these
vulnerabilities.
Details
=======
H.323 is the International Telecommunication Union (ITU) standard for
real-time multimedia communications and conferencing over
packet-based (IP) networks. A subset of the H.323 standard is
H.225.0, a standard that is used for call signaling protocols and
media stream packetization over IP networks.
The H.323 implementation in Cisco IOS Software contains two DoS
vulnerabilities. An attacker can exploit these vulnerabilities
remotely by sending crafted H.323 packets to an affected device that
is running Cisco IOS Software. A TCP three-way handshake is required
to exploit these vulnerabilities.
These vulnerabilities are documented in Cisco Bug IDs CSCtc73759 (
registered customers only) and CSCtd33567 ( registered customers
only) , and have been assigned Common Vulnerabilities and Exposures
(CVE) IDs CVE-2010-2828 and CVE-2010-2829, respectively.
Vulnerability Scoring Details
=============================
Cisco has provided scores for the vulnerabilities in this advisory
based on the Common Vulnerability Scoring System (CVSS). The CVSS
scoring in this Security Advisory is done in accordance with CVSS
version 2.0.
CVSS is a standards-based scoring method that conveys vulnerability
severity and helps determine urgency and priority of response.
Cisco has provided a base and temporal score. Customers can then
compute environmental scores to assist in determining the impact of
the vulnerability in individual networks.
Cisco has provided an FAQ to answer additional questions regarding
CVSS at
http://www.cisco.com/web/about/security/intelligence/cvss-qandas.html
Cisco has also provided a CVSS calculator to help compute the
environmental impact for individual networks at
http://intellishield.cisco.com/security/alertmanager/cvss
CSCtc73759 - Device crashing upon receipt of specific traffic

Impact
======
Successful exploitation of the vulnerabilities described in this
advisory may cause the affected device to reload. Theses
vulnerabilities could be exploited repeatedly to cause an extended
DoS condition.
Software Versions and Fixes
===========================
When considering software upgrades, also consult
http://www.cisco.com/go/psirt and any subsequent advisories to
determine exposure and a complete upgrade solution.
In all cases, customers should exercise caution to be certain the
devices to be upgraded contain sufficient memory and that current
hardware and software configurations will continue to be supported
properly by the new release. If the information is not clear, contact
the Cisco Technical Assistance Center (TAC) or your contracted
maintenance provider for assistance.
Each row of the following Cisco IOS Software table corresponds to a
Cisco IOS Software train. If a particular train is vulnerable, the
earliest releases that contain the fix are listed in the First Fixed
Release For This Advisory column. The First Fixed Release for All
Advisories in the September 2010 Bundle Publication column lists the
earliest possible releases that correct all the published
vulnerabilities in the Cisco IOS Software Security Advisory bundled
publication. Cisco recommends upgrading to the latest available
release, where possible.

Workarounds
===========
There are no workarounds to mitigate these vulnerabilities apart from
disabling H.323 if the Cisco IOS device does not require it. Applying
access lists on interfaces that should not accept H.323 traffic and
placing firewalls in strategic locations may greatly reduce exposure
until an upgrade can be performed.
Cisco provides Solution Reference Network Design (SRND) guides to
help design and deploy networking solutions, which can be found at
http://www.cisco.com/go/srnd Voice Security best practices are
covered in the Cisco Unified Communications SRND Based on Cisco
Unified Communications Manager 6.x at
http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/srnd/6x/security.html
To disable all H.323 call processing, administrators can issue the
call service stop forced command under the voice service voip mode,
as shown in this example:
voice service voip
h323
call service stop forced
Note: The call service stop forced command disables all H.323 call
processing.
Additional mitigations that can be deployed on Cisco devices within
the network are available in the companion document "Cisco Applied
Mitigation Bulletin: Identifying and Mitigating Exploitation of the
Multiple Vulnerabilities in Cisco Voice Products", which is available
at the following location:
http://www.cisco.com/warp/public/707/cisco-amb-20100922-voice.shtml

Protocol Denial of Service Vulnerabilities
Advisory ID: cisco-sa-20100922-sip
http://www.cisco.com/warp/public/707/cisco-sa-20100922-sip.shtml
Revision 1.0
For Public Release 2010 September 22 1600 UTC (GMT)
- ---------------------------------------------------------------------
Summary
=======
Multiple vulnerabilities exist in the Session Initiation Protocol
(SIP) implementation in Cisco IOS^ Software that could allow an
unauthenticated, remote attacker to cause a reload of an affected
device when SIP operation is enabled.
Cisco has released free software updates that address these
vulnerabilities. There are no workarounds for devices that must run
SIP; however, mitigations are available to limit exposure to the
vulnerabilities.
This advisory is posted at
http://www.cisco.com/warp/public/707/cisco-sa-20100922-sip.shtml
Note: The September 22, 2010, Cisco IOS Software Security Advisory
bundled publication includes six Cisco Security Advisories. Five of
the advisories address vulnerabilities in Cisco IOS Software, and one
advisory addresses vulnerabilities in Cisco Unified Communications
Manager. Each advisory lists the releases that correct the
vulnerability or vulnerabilities detailed in the advisory. The table
at the following URL lists releases that correct all Cisco IOS
Software vulnerabilities that have been published on September 22,
2010, or earlier:
http://www.cisco.com/warp/public/707/cisco-sa-20100922-bundle.shtml
Individual publication links are in "Cisco Event Response: Semiannual
Cisco IOS Software Security Advisory Bundled Publication" at the
following link:
http://www.cisco.com/web/about/security/intelligence/Cisco_ERP_sep10.html
Cisco Unified Communications Manager (CUCM) is affected by the
vulnerabilities described in this advisory. Two separate Cisco
Security Advisories have been published to disclose the
vulnerabilities that affect the Cisco Unified Communications Manager
at the following locations:
http://www.cisco.com/warp/public/707/cisco-sa-20090826-cucm.shtml
http://www.cisco.com/warp/public/707/cisco-sa-20100922-cucm.shtml
Affected Products
=================
These vulnerabilities only affect devices running Cisco IOS Software
with SIP voice services enabled.
Vulnerable Products
+------------------
Cisco devices are affected when they are running affected Cisco IOS
Software versions that are configured to process SIP messages.
Recent versions of Cisco IOS Software do not process SIP messages by
default. Creating a dial peer by issuing the dial-peer voice command
will start the SIP processes, causing the Cisco IOS device to process
SIP messages. In addition, several features within Cisco Unified
Communications Manager Express, such as ePhones, will also
automatically start the SIP process when they are configured, causing
the device to start processing SIP messages. An example of an
affected configuration follows:
dial-peer voice <Voice dial-peer tag> voip
...
!
In addition to inspecting the Cisco IOS device configuration for a
dial-peer command that causes the device to process SIP messages,
administrators can also use the show processes | include SIP command
to determine whether Cisco IOS Software is running the processes that
handle SIP messages. In the following example, the presence of the
processes CCSIP_UDP_SOCKET or CCSIP_TCP_SOCKET indicates that the
Cisco IOS device will process SIP messages:
Router# show processes | include SIP
149 Mwe 40F48254 4 1 400023108/24000 0 CCSIP_UDP_SOCKET
150 Mwe 40F48034 4 1 400023388/24000 0 CCSIP_TCP_SOCKET
Note: Because there are several ways a device running Cisco IOS
Software can start processing SIP messages, it is recommended that
the show processes | include SIP command be used to determine whether
the device is processing SIP messages instead of relying on the
presence of specific configuration commands.
Cisco Unified Border Element images are also affected by two of these
vulnerabilities.
Note: The Cisco Unified Border Element feature (previously known as
the Cisco Multiservice IP-to-IP Gateway) is a special Cisco IOS
Software image that runs on Cisco multiservice gateway platforms. It
provides a network-to-network interface point for billing, security,
call admission control, quality of service, and signaling
interworking.
To determine the Cisco IOS Software release that is running on a
Cisco product, administrators can log in to the device and issue the
show version command to display the system banner. The system banner
confirms that the device is running Cisco IOS Software by displaying
text similar to "Cisco Internetwork Operating System Software" or
"Cisco IOS Software." The image name displays in parentheses,
followed by "Version" and the Cisco IOS Software release name. Other
Cisco devices do not have the show version command or may provide
different output.
The following example identifies a Cisco product that is running
Cisco IOS Software Release 12.3(26) with an installed image name of
C2500-IS-L:
Router# show version
Cisco Internetwork Operating System Software
IOS (tm) 2500 Software (C2500-IS-L), Version 12.3(26), RELEASE SOFTWARE (fc2)

Note: CUCM is affected by the vulnerabilities described in this
advisory. Two separate Cisco Security Advisories have been published
to disclose the vulnerabilities that affect the Cisco Unified
Communications Manager at the following locations:
http://www.cisco.com/warp/public/707/cisco-sa-20090826-cucm.shtml
http://www.cisco.com/warp/public/707/cisco-sa-20100922-cucm.shtml
Products Confirmed Not Vulnerable
+--------------------------------
The SIP Application Layer Gateway (ALG), which is used by the Cisco
IOS NAT and firewall features of Cisco IOS Software, is not affected
by these vulnerabilities.
Cisco IOS XR Software is not affected by these vulnerabilities.
No other Cisco products are currently known to be affected by these
vulnerabilities.
Details
=======
SIP is a popular signaling protocol that is used to manage voice and
video calls across IP networks such as the Internet. SIP is
responsible for handling all aspects of call setup and termination.
Voice and video are the most popular types of sessions that SIP
handles, but the protocol has the flexibility to accommodate other
applications that require call setup and termination. SIP call
signaling can use UDP (port 5060), TCP (port 5060), or Transport
Layer Security (TLS; TCP port 5061) as the underlying transport
protocol.
Three vulnerabilities exist in the SIP implementation in Cisco IOS
Software that may allow a remote attacker to cause an affected device
to reload. These vulnerabilities are triggered when the device
running Cisco IOS Software processes crafted SIP messages.
Note: In cases where SIP is running over TCP transport, a TCP
three-way handshake is necessary to exploit these vulnerabilities.
These vulnerabilities are addressed by Cisco bug IDs CSCta20040,
CSCsz43987 and CSCtf72678, and have been assigned Common
Vulnerabilities and Exposures (CVE) IDs CVE-2010-2835, CVE-2009-2051
and CVE-2010-2834, respectively.
Vulnerability Scoring Details
=============================
Cisco has provided scores for the vulnerabilities in this advisory
based on the Common Vulnerability Scoring System (CVSS). The CVSS
scoring in this Security Advisory is done in accordance with CVSS

Cisco IOS XR System Software
+---------------------------
Cisco IOS XR Software is not affected by the vulnerabilities
disclosed in the September 22, 2010, Cisco IOS Software Security
Advisory bundled publication.
Workarounds
===========
If the affected Cisco IOS device requires SIP for VoIP services, SIP
cannot be disabled, and no workarounds are available. Users are
advised to apply mitigation techniques to help limit exposure to the
vulnerabilities. Mitigation consists of allowing only legitimate
devices to connect to affected devices. To increase effectiveness,
the mitigation must be coupled with anti-spoofing measures on the
network edge. This action is required because SIP can use UDP as the
transport protocol.
Additional mitigations that can be deployed on Cisco devices within
the network are available in the companion document "Cisco Applied
Mitigation Bulletin:Identifying and Mitigating Exploitation of the
Multiple Vulnerabilities in Cisco Voice Products", which is available
at the following location:
http://www.cisco.com/warp/public/707/cisco-amb-20100922-voice.shtml
Disabling SIP Listening Ports
+----------------------------
For devices that do not require SIP to be enabled, the simplest and
most effective workaround is to disable SIP processing on the device.
Some versions of Cisco IOS Software allow administrators to disable
SIP with the following commands:
sip-ua
no transport udp
no transport tcp
no transport tcp tls
warning Warning: When applying this workaround to devices that are
processing Media Gateway Control Protocol (MGCP) or H.323 calls, the
device will not stop SIP processing while active calls are being
processed. Under these circumstances, this workaround should be
implemented during a maintenance window when active calls can be
briefly stopped.
The show udp connections, show tcp brief all, and show processes |
include SIP commands can be used to confirm that the SIP UDP and TCP
ports are closed after applying this workaround.
Depending on the Cisco IOS Software version in use, the output from
the show ip sockets command may still show the SIP ports open, but
sending traffic to them will cause the SIP process to emit the
following message:
*Jun 2 11:36:47.691: sip_udp_sock_process_read: SIP UDP Listener is DISABLED
Control Plane Policing
+---------------------
For devices that need to offer SIP services, it is possible to use
Control Plane Policing (CoPP) to block SIP traffic to the device from
untrusted sources. Cisco IOS Releases 12.0S, 12.2SX, 12.2S, 12.3T,
12.4, and 12.4T support the CoPP feature. CoPP may be configured on a
device to protect the management and control planes to minimize the
risk and effectiveness of direct infrastructure attacks by explicitly
permitting only authorized traffic sent to infrastructure devices in
accordance with existing security policies and configurations. The
following example can be adapted to specific network configurations:
!-- The 192.168.1.0/24 network and the 172.16.1.1 host are trusted.
!-- Everything else is not trusted. The following access list is used
!-- to determine what traffic needs to be dropped by a control plane
!-- policy (the CoPP feature.) If the access list matches (permit)
!-- then traffic will be dropped and if the access list does not
!-- match (deny) then traffic will be processed by the router.
access-list 100 deny udp 192.168.1.0 0.0.0.255 any eq 5060
access-list 100 deny tcp 192.168.1.0 0.0.0.255 any eq 5060
access-list 100 deny tcp 192.168.1.0 0.0.0.255 any eq 5061
access-list 100 deny udp host 172.16.1.1 any eq 5060
access-list 100 deny tcp host 172.16.1.1 any eq 5060
access-list 100 deny tcp host 172.16.1.1 any eq 5061
access-list 100 permit udp any any eq 5060
access-list 100 permit tcp any any eq 5060
access-list 100 permit tcp any any eq 5061
!-- Permit (Police or Drop)/Deny (Allow) all other Layer3 and Layer4
!-- traffic in accordance with existing security policies and
!-- configurations for traffic that is authorized to be sent
!-- to infrastructure devices.
!-- Create a Class-Map for traffic to be policed by
!-- the CoPP feature.
class-map match-all drop-sip-class
match access-group 100
!-- Create a Policy-Map that will be applied to the
!-- Control-Plane of the device.
policy-map control-plane-policy
class drop-sip-class
drop
!-- Apply the Policy-Map to the Control-Plane of the
!-- device.
control-plane
service-policy input control-plane-policy
Note: Because SIP can use UDP as a transport protocol, it is possible
to easily spoof the IP address of the sender, which may defeat access
control lists that permit communication to these ports from trusted
IP addresses.
In the above CoPP example, the access control entries (ACEs) that
match the potential exploit packets with the "permit" action result
in these packets being discarded by the policy-map "drop" function,
while packets that match the "deny" action (not shown) are not
affected by the policy-map drop function. Additional information on
the configuration and use of the CoPP feature can be found at
http://www.cisco.com/web/about/security/intelligence/coppwp_gs.html
and http://www.cisco.com/en/US/docs/ios/12_3t/12_3t4/feature/guide/gtrtlimt.html
Obtaining Fixed Software
========================
Cisco has released free software updates that address these
vulnerabilities. Prior to deploying software, customers should
consult their maintenance provider or check the software for feature
set compatibility and known issues specific to their environment.
Customers may only install and expect support for the feature sets
they have purchased. By installing, downloading, accessing or
otherwise using such software upgrades, customers agree to be bound
by the terms of Cisco's software license terms found at
http://www.cisco.com/en/US/docs/general/warranty/English/EU1KEN_.html
or as otherwise set forth at Cisco.com Downloads at
http://www.cisco.com/public/sw-center/sw-usingswc.shtml
Do not contact psirt(a)cisco.com or security-alert(a)cisco.com for

Cisco Security Advisory: Cisco IOS Software Internet Group Management
Protocol Denial of Service Vulnerability
Advisory ID: cisco-sa-20100922-igmp
http://www.cisco.com/warp/public/707/cisco-sa-20100922-igmp.shtml
Revision 1.0
For Public Release 2010 September 22 1600 UTC (GMT)
- ---------------------------------------------------------------------
Summary
=======
A vulnerability in the Internet Group Management Protocol (IGMP)
version 3 implementation of Cisco IOS Software and Cisco IOS XE
Software allows a remote unauthenticated attacker to cause a reload
of an affected device. Repeated attempts to exploit this
vulnerability could result in a sustained denial of service (DoS)
condition. Cisco has released free software updates that address this
vulnerability.
This advisory is posted at
http://www.cisco.com/warp/public/707/cisco-sa-20100922-igmp.shtml
Note: The September 22, 2010, Cisco IOS Software Security Advisory
bundled publication includes six Cisco Security Advisories. Five of
the advisories address vulnerabilities in Cisco IOS Software, and one
advisory addresses vulnerabilities in Cisco Unified Communications
Manager. Each advisory lists the releases that correct the
vulnerability or vulnerabilities detailed in the advisory. The table
at the following URL lists releases that correct all Cisco IOS
Software vulnerabilities that have been published on September 22,
2010, or earlier:
http://www.cisco.com/warp/public/707/cisco-sa-20100922-bundle.shtml

Affected Products
=================
Vulnerable Products
+------------------
The following products are affected by this vulnerability:
* Cisco IOS Software
* Cisco IOS XE Software
To determine the Cisco IOS Software release that is running on a
Cisco product, administrators can log in to the device and issue
the show version command to display the system banner. The system
banner confirms that the device is running Cisco IOS Software by
displaying text similar to "Cisco Internetwork Operating System
Software" or "Cisco IOS Software." The image name displays in
parentheses, followed by "Version" and the Cisco IOS Software
release name. Other Cisco devices do not have the show version
command or may provide different output.
The following example identifies a Cisco product that is running
Cisco IOS Software Release 12.4(20)T with an installed image name
of C1841-ADVENTERPRISEK9-M:
Router#show version
Cisco IOS Software, 1841 Software (C1841-ADVENTERPRISEK9-M), Version 12.4(20)T, RELEASE SOFTWARE (fc3)

conventions is available in White Paper: Cisco IOS and NX-OS
Software Reference Guide.
Products Confirmed Not Vulnerable
+--------------------------------
No other Cisco products are currently known to be affected by this
vulnerability. Cisco IOS XR Software is not affected by this
vulnerability.
The IGMP version 1, IGMP version 2, and IPv6 Multicast Listener
Discovery protocol (MLD) features in Cisco IOS and Cisco IOS XE
Software are not affected by this vulnerability.
Details
=======
Internet Group Management Protocol (IGMP) is the protocol used by
hosts and adjacent routers to manage membership in IP multicast
groups. The IGMP version 3 protocol permits source-specific multicast
which allows hosts to specify the IP address of the multicast source.
A malformed IGMP packet can cause a vulnerable device to reload. This
vulnerability can only be exploited if the malformed IGMP packet is
received on an interface that has been enabled for IGMP version 3 and
Protocol Independent Multicast (PIM). The malformed IGMP packet
destination address can be unicast, multicast, or broadcast and can
be addressed to any IP address in the vulnerable device, including
loopback addresses.
To exploit this vulnerability, a malformed packet must be received on
a vulnerable interface, but it can be addressed to any IP address on
the vulnerable device.
Transit traffic will not trigger this vulnerability.
A vulnerable interface configuration requires the PIM mode of
operation (sparse-dense, sparse, or dense) to be configured in
addition to the ip igmp version 3 command. The three possible
configurations that permit exploitation of this vulnerability are:
!--- Interface configured for PIM sparse and IGMPv3
interface GigabitEthernet0/0
ip address 192.168.0.1 255.255.255.0
ip pim sparse-mode
ip igmp version 3
!--- Interface configured for PIM sparse-dense and IGMPv3
interface GigabitEthernet0/1
ip address 192.168.1.1 255.255.255.0
ip pim sparse-dense-mode
ip igmp version 3
!--- Interface configured for PIM dense and IGMPv3
interface GigabitEthernet0/2
ip address 192.168.2.1 255.255.255.0
ip pim dense-mode
ip igmp version 3
The IGMP version 3 lite feature is unrelated to this vulnerability,
in that the presence or absence of the ip igmp v3lite command on an
interface does not change the vulnerable condition of that interface.
The IP router alert option may or may not be present in packets
attempting to exploit the vulnerability described in this document.
This vulnerability is documented in Cisco bug ID CSCte14603 (
registered customers only) . This vulnerability has been assigned
Common Vulnerabilities and Exposures (CVE) ID CVE-2010-2830.
Vulnerability Scoring Details

Impact
======
Successful exploitation of this vulnerability may cause the affected
device vulnerable device to reload. Repeated exploitation may result
in a sustained DoS condition.
Software Versions and Fixes
===========================
When considering software upgrades, also consult
http://www.cisco.com/go/psirt and any subsequent advisories to
determine exposure and a complete upgrade solution.
In all cases, customers should exercise caution to be certain the
devices to be upgraded contain sufficient memory and that current
hardware and software configurations will continue to be supported
properly by the new release. If the information is not clear, contact
the Cisco Technical Assistance Center (TAC) or your contracted
maintenance provider for assistance.
Each row of the following Cisco IOS Software table corresponds to a
Cisco IOS Software train. If a particular train is vulnerable, the
earliest releases that contain the fix are listed in the First Fixed
Release For This Advisory column. The First Fixed Release for All
Advisories in the September 2010 Bundle Publication column lists the
earliest possible releases that correct all the published
vulnerabilities in the Cisco IOS Software Security Advisory bundled
publication. Cisco recommends upgrading to the latest available
release, where possible.

Advisory bundle publication.
Workarounds
===========
Additional mitigations that can be deployed on Cisco devices within
the network are available in the Cisco Applied Mitigation Bulletin
companion document for this advisory, which is available at the
following link:
http://www.cisco.com/warp/public/707/cisco-amb-20100922-igmp.shtml
IGMP version 2
+-------------
Customers who do not require the Source Specific Multicast (SSM)
functionality can use IGMP version 2 as a workaround.
interface GigabitEthernet0/0
ip address 192.168.0.1 255.255.255.0
ip pim sparse-mode
ip igmp version 2
Control Plane Policing
+---------------------
A partial mitigation of the vulnerability described in this document
is to block IGMP packets with an IP Time to Live (TTL) field value
that is not equal to 1. RFC1054 leavingcisco.com, "Host Extensions
for IP Multicasting" RFC2236 leavingcisco.com, "Internet Group
Management Protocol Version 2", and RFC3376 leavingcisco.com,
"Internet Group Management Protocol Version 3", indicate that every
IGMP message is sent with an IP TTL of 1.
CoPP may be configured on a device to protect the management and
control planes, and minimize the risk and effectiveness of direct
infrastructure attacks by explicitly permitting only authorized
traffic sent to infrastructure devices in accordance with existing
security policies and configurations. The following example can be
adapted to your network. Drop of IGMP packets with unicast IP
destination addresses can also be implemented with CoPP if the
network is using all multicast applications that utilize only
multicast group destination addresses for IGMP packets.

We do the same with HE, but we announce a /32 we have from arin. I think
most of our upstreams do native ipv6 I'm just to lazy to flip the switches.
Considering were not really giving ipv6 to customers yet(soon). Even when
we go native, I figure we'll keep a session with HE, Don't see any
disadvantages of it..

With BGP it does.
We are announcing a provider independent /48 address space, and receive the
ipv6 bgp routes.

Neither of our upstream providers offer direct ipv6 although both claim deployment in Q1 2011. In the meantime, we have a tunnel with BGP to HE announcing our /48, but we are looking for redundancy. Is there anyone else out there offering services like Hurricane Electric?

If you can choose your rack equipment, you should look at Ortronics
Might Mo 10. It is very stable and has plenty of cable management
options. They are kind of a cross between a two post and a cabinet.
Basicaly the side cannel is 16.25 inces deep. Unfortunatly, the 6500 has
slot spacing that doesn't line up with rack U's so most cable management
will not work perfectly. The Might Mo can handle the density but make
sure you use the largest vertical channels you have room for. You
probably are not interested in doors but in locations where this is
desired, the doors over the vertical channels hinge both wasy and remove
easier than anything I've seen.
You probably want to look at the air baffles since the 6509/6513 have
right to left airflow rather than front to back. One fo the features in
the Mighty Mo 10 is the ventilated side channels and available baffles.
The airflow can actualy be one of your biggest challenges if you have
6509/6513's in adjacent cabinets. The warm air from one can blow into
the input of the switch to the left.
You could also look at using the WS-C6509-V-E chassis with front to back
airflow and built in cable management.

Greetings,
I am planning on deploying a console access server on my network for
20-30 network devices including routers, wireless controllers and other
devices. The design is to have one central device for all console access.
Due to the geographic diversity of my campus, I will need need to carry
the async serial connections over my fiber plant with long reach optics
and single mode fiber. I have the fiber plant to support this design.
I have been researching solutions to implement the serial part, but I am
not very familiar with the vendors I am coming up with. For instance, I
know Black Box Networks makes products like this but they only seem to
have stand alone devices. I was hoping for something rack mountable
since I will have a dense deployment of these devices.
Does anyone have experience deploying a solution like this or with async
serial fiber transceivers in general? I welcome any suggestions.
-Chris

Hi,
I have a SSG-140 Juniper Firewall. I need to ask, how can I Monitor the individual IP traffic? I mean I want to see who is taking more bandwidth.
Please help me out. Thanks
