Cisco has released free software updates that address these vulnerabilities. Workarounds that mitigate these vulnerabilities are available. This advisory is posted at http://www.cisco.com/warp/public/707/cisco-sa-20080924-multicast.shtml Note: The September 24, 2008 IOS Advisory bundled publication includes twelve Security Advisories. Eleven of the advisories address vulnerabilities in Cisco's IOS software, and one advisory addresses vulnerabilities in Cisco Unified Communications Manager. Each Advisory lists the releases that correct the vulnerability described in the Advisory. Please reference the following software table to find a release that fixes all published IOS software Advisories as of September 24th, 2008: http://www.cisco.com/warp/public/707/cisco-sa-20080924-bundle.shtml Individual publication links are listed below: * http://www.cisco.com/warp/public/707/cisco-sa-20080924-iosips.shtml * http://www.cisco.com/warp/public/707/cisco-sa-20080924-ssl.shtml * http://www.cisco.com/warp/public/707/cisco-sa-20080924-sip.shtml * http://www.cisco.com/warp/public/707/cisco-sa-20080924-cucm.shtml * http://www.cisco.com/warp/public/707/cisco-sa-20080924-vpn.shtml * http://www.cisco.com/warp/public/707/cisco-sa-20080924-mfi.shtml * http://www.cisco.com/warp/public/707/cisco-sa-20080924-ipc.shtml * http://www.cisco.com/warp/public/707/cisco-sa-20080924-ubr.shtml * http://www.cisco.com/warp/public/707/cisco-sa-20080924-sccp.shtml * http://www.cisco.com/warp/public/707/cisco-sa-20080924-iosfw.shtml * http://www.cisco.com/warp/public/707/cisco-sa-20080924-l2tp.shtml Affected Products ================= Vulnerable Products +------------------ Devices that are running Cisco IOS Software and configured for PIM have a vulnerability related to a specially crafted PIM packet. In addition, Cisco 12000 Series (GSR) routers running Cisco IOS Software have a second vulnerability related to a crafted PIM packet. The show running-config | include ip pim command can be issued to verify that a Cisco IOS device is configured for PIM. In the following example, the Cisco IOS router is configured for PIM sparse-dense mode. Router#show running-config | include ip pim ip pim sparse-dense-mode Note that available PIM modes on a Cisco IOS device are dense mode, sparse mode, or sparse-dense mode. A device that is configured for any of these modes is affected by these vulnerabilities. The mode determines how the device populates its multicast routing table and how multicast packets are forwarded. PIM must be enabled in one of these modes for an interface to perform IP multicast routing. More information on the configuration of each mode is in the "Details" section. Additionally, To display information about interfaces configured for Protocol Independent Multicast (PIM), use the show ip pim interface command in user EXEC or privileged EXEC mode, as shown in the following example: Router# show ip pim interface Address Interface Ver/ Nbr Query DR DR Mode Count Intvl Prior 10.1.0.1 GigabitEthernet0/0 v2/SD 0 30 1 10.1.0.1 10.6.0.1 GigabitEthernet0/1 v2/SD 1 30 1 10.6.0.2 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, 7200 Software (C7200-ADVSECURITYK9-M), Version 12.4(6)T2, RELEASE SOFTWARE (fc1) Technical Support: http://www.cisco.com/techsupport Copyright (c) 1986-2006 by Cisco Systems, Inc. Compiled Tue 16-May-06 16:09 by kellythw <more output removed for brevity> Products Confirmed Not Vulnerable +-------------------------------- Cisco IOS devices that are not configured for PIM are not vulnerable. Cisco IOS XR Software is not affected by this vulnerability. No other Cisco products are currently known to be affected by this vulnerability. Details ======= Two crafted Protocol Independent Multicast (PIM) packet vulnerabilities exist in Cisco IOS Software that may lead to a denial of service (DoS) condition. Devices that run Cisco IOS Software and are configured for PIM are affected by the first vulnerability. Only Cisco 12000 Series (GSR) routers that are configured for PIM are affected by the second vulnerability. Available PIM modes on a Cisco IOS device are dense mode, sparse mode, or sparse-dense mode. The mode determines how the device populates its multicast routing table and how multicast packets are forwarded. PIM must be enabled in one of these modes for an interface to perform IP multicast routing. Note: There is no default mode setting. By default, multicast routing is disabled on an interface. To configure PIM on an interface to be in dense mode, use the following command in interface configuration mode: Router(config-if)# ip pim dense-mode To configure PIM on an interface to be in sparse mode, use the following command in interface configuration mode: Router(config-if)# ip pim sparse-mode To configure PIM on an interface to be in sparse-dense mode, use the following command in interface configuration mode: Router(config-if)# ip pim sparse-dense-mode These vulnerabilities are documented in the following Cisco Bug IDs: * CSCsd95616 - Crafted PIM packets may cause an IOS device to reload * CSCsl34355 - GSR may crash with malformed PIM packets These vulnerabilities have been assigned the Common Vulnerabilities and Exposures (CVE) identifiers CVE-2008-3808 and CVE-2008-3809. 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 CSCsd95616 - Crafted PIM packets may cause an IOS device to reload CVSS Base Score - 7.8 Access Vector - Network Access Complexity - Low Authentication - None Confidentiality Impact - None Integrity Impact - None Availability Impact - Complete CVSS Temporal Score - 6.4 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed CSCsl34355 - GSR may crash with malformed PIM packets CVSS Base Score - 7.8 Access Vector - Network Access Complexity - Low Authentication - None Confidentiality Impact - None Integrity Impact - None Availability Impact - Complete CVSS Temporal Score - 6.4 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed Impact ====== Successful exploitation may cause a reload of the affected device. Repeated exploitation could result in a sustained 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 Cisco IOS software table (below) names a Cisco IOS release train. If a given release train is vulnerable, then the earliest possible releases that contain the fix (along with the anticipated date of availability for each, if applicable) are listed in the "First Fixed Release" column of the table. The "Recommended Release" column indicates the releases which have fixes for all the published vulnerabilities at the time of this Advisory. A device running a release in the given train that is earlier than the release in a specific column (less than the First Fixed Release) is known to be vulnerable. Cisco recommends upgrading to a release equal to or later than the release in the "Recommended Releases" column of the table. +-------------------------------------------------------------------+ | Major | Availability of Repaired Releases | | Release | | |------------+------------------------------------------------------| | Affected | | Recommended | | 12.0-Based | First Fixed Release | Release | | Releases | | | |------------+---------------------------------------+--------------| | | | 12.4(15)T7 | | 12.0 | Vulnerable;

A PIM router must receive PIM Hellos to establish PIM neighborship. PIM neighborship is also the basis for designated router (DR) election, DR failover, and accepting/sending PIM Join/ Prune/Assert messages. To specify trusted PIM neighbors, use the ip pim neighbor-filter command, as shown in the following example: Router(config)#access-list 1 permit host 10.10.10.123 !-- An access control list is created to allow a trusted PIM neighbor !-- in this example the neighbor is 10.10.10.123 ! Router(config)#interface fastEthernet 0/0 Router(config-if)#ip pim neighbor-filter 1 !-- The PIM neighbor filter is then applied to the respective interface(s) The ip pim neighbor-filter command filters PIM packets from untrusted devices including Hellos, Join/Prune, and BSR packets. Note: The vulnerabilities described in this document can be exploited by spoofed IP packets if the attacker knows the IP address of the trusted PIM neighbors listed in the ip pim neighbor-filter implementation. To protect infrastructure devices and minimize the risk, impact, and effectiveness of direct infrastructure attacks, administrators are advised to deploy ACLs to perform policy enforcement of traffic sent to core infrastructure equipment. PIM is IP protocol 103. As an additional workaround, administrators can explicitly permit only authorized PIM (IP protocol 103) traffic sent to infrastructure devices in accordance with existing security policies and configurations. An ACL can be deployed as shown in the following example: ip access-list extended Infrastructure-ACL-Policy ! !-- When applicable, include explicit permit statements for trusted !-- sources that require access on the vulnerable protocol !-- PIM routers need to communicate with the rendezvous point (RP). !-- In this example, 192.168.100.1 is the IP address of the !-- rendezvous point, which is a trusted host that requires access !-- to and from the affected PIM devices. ! permit pim host 192.168.100.1 192.168.60.0 0.0.0.255 permit pim 192.168.60.0 0.0.0.255 host 192.168.100.1 ! !-- Permit PIM segment traffic, packets have destination of: !-- 224.0.0.13 (PIMv2) !-- 224.0.0.2 (Required only by legacy PIMv1) ! permit pim 192.168.60.0 0.0.0.255 host 224.0.0.13 permit pim 192.168.60.0 0.0.0.255 host 224.0.0.2 ! !-- The following vulnerability-specific access control entries !-- (ACEs) can aid in identification of attacks ! deny pim any 192.168.60.0 0.0.0.255 ! !-- Explicit deny ACE for traffic sent to addresses configured within !-- the infrastructure address space ! deny ip any 192.168.60.0 0.0.0.255 ! !-- Permit/deny all other Layer 3 and Layer 4 traffic in accordance !-- with existing security policies and configurations ! !-- Apply iACL to interfaces in the ingress direction ! interface GigabitEthernet0/0 ip access-group Infrastructure-ACL-Policy in Obtaining Fixed Software ======================== Cisco has released free software updates that address these vulnerabilities.
