-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 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) Technical Support: http://www.cisco.com/techsupport Copyright (c) 1986-2009 by Cisco Systems, Inc. Compiled Wed 02-Dec-09 17:17 by prod_rel_team <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 CSCtf17624 - NAT SIP DoS Vulnerability 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 CSCtf91428 - NAT for H.323 DoS 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 CSCtd86472 - NAT for H.225.0 DoS 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 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.

NAT for H.323 DoS Vulnerability +------------------------------ Mitigation for this vulnerability consists of disabling NAT for H.323 and H.225.0 using the no ip nat service h225 global configuration command. NAT for H.225.0 DoS vulnerability +-------------------------------- Mitigation for this vulnerability consists of disabling NAT for H.323 and H.225.0 using the no ip nat service h225 global configuration command. 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@cisco.com or security-alert@cisco.com for software upgrades. Customers with Service Contracts +------------------------------- Customers with contracts should obtain upgraded software through their regular update channels. For most customers, this means that upgrades should be obtained through the Software Center on Cisco's worldwide website at http://www.cisco.com Customers using Third Party Support Organizations +------------------------------------------------ Customers whose Cisco products are provided or maintained through prior or existing agreements with third-party support organizations, such as Cisco Partners, authorized resellers, or service providers should contact that support organization for guidance and assistance with the appropriate course of action in regards to this advisory. The effectiveness of any workaround or fix is dependent on specific customer situations, such as product mix, network topology, traffic behavior, and organizational mission. Due to the variety of affected products and releases, customers should consult with their service provider or support organization to ensure any applied workaround or fix is the most appropriate for use in the intended network before it is deployed. Customers without Service Contracts +---------------------------------- Customers who purchase direct from Cisco but do not hold a Cisco service contract, and customers who purchase through third-party vendors but are unsuccessful in obtaining fixed software through their point of sale should acquire upgrades by contacting the Cisco Technical Assistance Center (TAC). TAC contacts are as follows. * +1 800 553 2447 (toll free from within North America) * +1 408 526 7209 (toll call from anywhere in the world) * e-mail: tac@cisco.com Customers should have their product serial number available and be prepared to give the URL of this notice as evidence of entitlement to a free upgrade.
