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 software updates that address these vulnerabilities. This advisory is posted at http://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20100922-nat. 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://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20100922-bundle 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 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:
Vulmon
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
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.
The three vulnerabilities are triggered by transit traffic that needs to be processed by the NAT feature. Each vulnerability is independent of each other.
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 ( registered customers only) and has been assigned Common Vulnerabilities and Exposures (CVE) ID CVE-2010-2831.
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 ( registered customers only) and has been assigned Common Vulnerabilities and Exposures (CVE) IDs CVE-2010-2832.
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 ( registered customers only) and has been assigned Common Vulnerabilities and Exposures (CVE) IDs CVE-2010-2833.
The mitigations for the NAT vulnerabilities disable the respective Application Layer Gateway NAT processing. That is, packets will continue to be translated at the network and transport layers, but the embedded IP addresses will not be translated.
Mitigation for this vulnerability consists of disabling NAT for SIP over the UDP transport by using the no ip nat service sip udp port 5060 global configuration command.
Mitigation for this vulnerability consists of disabling NAT for H.323 and H.225.0 using the no ip nat service h425 global configuration command.
Mitigation for this vulnerability consists of disabling NAT for H.323 and H.225.0 using the no ip nat service h425 global configuration command.
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.
