-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Cisco Security Advisory: Cisco IOS Software Tunnels Vulnerability Advisory ID: cisco-sa-20090923-tunnels Revision 1.0 For Public Release 2009 September 23 +--------------------------------------------------------------------- Summary ======= Cisco devices running affected versions of Cisco IOS Software are vulnerable to a denial of service (DoS) attack if configured for IP tunnels and Cisco Express Forwarding. Cisco has released free software updates that address this vulnerability. This advisory is posted at: http://www.cisco.com/warp/public/707/cisco-sa-20090923-tunnels.shtml Note: The September 23, 2009, Cisco IOS Security Advisory bundled publication includes eleven Security Advisories. Ten of the advisories address vulnerabilities in Cisco IOS Software, and one advisory addresses a vulnerability in Cisco Unified Communications Manager. Each advisory lists the releases that correct the vulnerability or vulnerabilities detailed in the advisory. The following table lists releases that correct all Cisco IOS Software vulnerabilities that have been published on September 23, 2009, or earlier. http://www.cisco.com/warp/public/707/cisco-sa-20090923-bundle.shtml Individual publication links are in "Cisco Event Response: Semiannual Cisco IOS Software Advisory Bundled Publication" at the following link: http://www.cisco.com/web/about/security/intelligence/Cisco_ERP_sep09.html Affected Products ================= Cisco devices are vulnerable when running an affected version of Cisco IOS Software and configured for Generic Routing Encapsulation (GRE), IPinIP, Generic Packet Tunneling in IPv6 or IPv6 over IP tunnels with Cisco Express Forwarding enabled. The Cisco IOS Point to Point Tunneling Protocol (PPTP) feature creates GRE tunnels that are transparent to the user. Therefore systems configured for PPTP are also vulnerable. The Cisco multicast Virtual Private Network (MVPN) feature also creates GRE tunnels that are transparent to the user, however MVPN configurations are not vulnerable, unless there are other tunnels that are configured explicitly. Vulnerable Products +------------------ A Cisco IOS device that is explicitly configured for a tunnel will have a configuration similar to the following in the output of "show running-config": interface tunnel0 ip address [IP-address] tunnel source [Tunnel-Source] tunnel destination [Tunnel Destination] An alternative method to identify devices that are configured for tunnels is to use the "show interfaces" command. A sample output is provided below: Router#show interfaces | include Tunnel Tunnel0 is up, line protocol is down Hardware is Tunnel [...] Tunnel protocol/transport GRE/IP !-- output truncated A Cisco IOS device that is configured for Cisco Express Forwarding will display the forwarding table in the output of "show ip cef" output, as in the following example: Router#show ip cef Prefix Next Hop Interface 0.0.0.0/0 10.48.64.1 Ethernet0/0 0.0.0.0/32 receive .... Cisco Express Forwarding is enabled by default in most Cisco IOS Software versions. 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 7200 series device running Cisco IOS Software release 12.3(19) with an installed image name of C7200-JS-M: 7200#show version Cisco Internetwork Operating System Software IOS (tm) 7200 Software (C7200-JS-M), Version 12.3(19), RELEASE SOFTWARE (fc2) Technical Support: http://www.cisco.com/techsupport Copyright (c) 1986-2006 by cisco Systems, Inc.

Compiled Wed 24-Jan-07 20:26 by ccai !-- output truncated Additional information about Cisco IOS Software release naming 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 +-------------------------------- Cisco IOS XR Software is not affected. Cisco IOS XE Software is not affected. IPsec and Dynamic Multipoint VPN (DMVPN) configurations that are protected by IPsec are not affected. MVPN configurations are not affected. Multiprotocol Label Switching (MPLS) Traffic Engineering (TE) tunnels are not affected. No other Cisco products are currently known to be affected by these vulnerabilities. Details ======= A tunnel protocol encapsulates a wide variety of protocol packet types inside IP tunnels, creating a virtual point-to-point link between internetworking devices over an IP network. Cisco Express Forwarding is a Layer 3 IP switching technology. It improves network performance and scalability for networks with high and dynamic traffic patterns. Devices that are running Cisco IOS Software and configured for GRE, IPinIP, Generic Packet Tunneling in IPv6 or IPv6 over IP tunnels tunnels and Cisco Express Forwarding may reload upon switching a specially crafted malformed packets. Please note that using PPTP creates GRE tunnels that are transparent to the end user so devices configured for PPTP are vulnerable if they are configured on an affected software version. Using MVPN also creates GRE tunnels that are transparent to the end user. However MVPN configurations are not vulnerable. These vulnerabilities are addressed by the Cisco Bug IDs CSCsh97579, CSCsq31776 and CSCsx70889 and have been assigned Common Vulnerabilities and Exposures (CVE) IDs CVE-2009-2872 and CVE-2009-2873. 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 CSCsh97579 - switching bad packet tunnel to tunnel crashes router CVSS Base Score - 7.1 Access Vector - Network Access Complexity - Medium Authentication - None Confidentiality Impact - None Integrity Impact - None Availability Impact - Complete CVSS Temporal Score - 5.9 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed CSCsq31776 - ip tunnels regression test can crash the router CVSS Base Score - 7.1 Access Vector - Network Access Complexity - Medium Authentication - None Confidentiality Impact - None Integrity Impact - None Availability Impact - Complete CVSS Temporal Score - 5.9 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed CSCsx70889 - Systems configured for tunnels reload after receiving malformed packets CVSS Base Score - 7.1 Access Vector - Network Access Complexity - Medium Authentication - None Confidentiality Impact - None Integrity Impact - None Availability Impact - Complete CVSS Temporal Score - 5.9 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed Impact ====== Successful exploitation of the vulnerability may result in the reload of an affected system, causing a 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(25b) | | 12.0 | Vulnerable;

It can be disabled in two ways: Disabling Cisco Express Forwarding Globally +------------------------------------------ Cisco Express Forwarding can be globally disabled by using the "no ip cef" global configuration command. Disabling Cisco Express Forwarding on Tunnel Interfaces +------------------------------------------------------ Cisco Express Forwarding can also be disabled on individual tunnel interfaces. To be effective, it must be disabled on all tunnel interfaces configured on an affected device. Cisco Express Forwarding can be disabled on individual interfaces as shown in the following example: interface Tunnel [interface-ID] no ip route-cache cef Note: Disabling Cisco Express Forwarding may have significant performance impact and is not recommended. Additional mitigations that can be deployed on Cisco devices in 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-20090923-tunnels.shtml 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.

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.
