Cisco IOS Software IPsec Vulnerability

Summary

• A malformed Internet Key Exchange (IKE) packet may cause a device running Cisco IOS Software to reload. Only Cisco 7200 Series and Cisco 7301 routers running Cisco IOS software with a VPN Acceleration Module 2+ (VAM2+) installed are affected. Cisco has released software updates that address this vulnerability.

  This advisory is posted at http://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20100324-ipsec.

  Note: The March 24, 2010, Cisco IOS Software Security Advisory bundled publication includes seven Security Advisories. All the advisories address vulnerabilities in Cisco IOS Software. 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 March 24, 2010, or earlier:

Affected Products

• Vulnerable Products

  Only Cisco 7200 Series and Cisco 7301 routers with VPN Acceleration Module 2+ (VAM2+) are affected by this vulnerability.

  To display a summary of the configuration information for the crypto engines and to determine if a VAM is present and used in the device, use the show crypto engine brief command, as shown in the following example:

  Router#show crypto engine brief
          crypto engine name:  Virtual Private Network (VPN) Module
          crypto engine type:  hardware
                       State:  Enabled 
                    Location:  slot 4
          VPN Module in slot:  4
                Product Name:  VAM2+ 
           Software Serial #:  55AA
                   Device ID:  001F - revision 0000
                   Vendor ID:  0000
                 Revision No:  0x001F0000
                VSK revision:  0
                Boot version:  902
                 DPU version:  0
                 HSP version:  3.4(3) (PRODUCTION)
                Time running:  00:00:10
                 Compression:  Yes
                         DES:  Yes
                       3 DES:  Yes
                     AES CBC:  Yes (128,192,256)
                    AES CNTR:  No
       Maximum buffer length:  4096
            Maximum DH index:  5120
            Maximum SA index:  5120
          Maximum Flow index:  10230

  Note: In the previous example, the "Product Name" VAM2+ is displayed, indicating that the router has the VAM2+ installed. The Enabled keyword under "State" indicates that the VAM2+ is enabled and active.

  IKE is enabled by default if IPsec is used. Cisco IOS devices that are configured for IKE will listen on UDP port 500, UDP port 4500 if the device is configured for NAT Traversal (NAT-T), or UDP ports 848 or 4848 if the device is configured for Group Domain of Interpretation (GDOI). The following outputs show a router that is listening on UDP port 500:

      Router#show ip sockets 
      Proto    Remote      Port      Local       Port  In Out Stat TTY OutputIF
      ....
       17   --listen--          192.168.66.129    500   0   0   11   0 
      ....
  
  Or
  
      Router#show udp
      Proto        Remote      Port      Local       Port  In Out  Stat TTY OutputIF
       17       --listen--          192.0.2.1         500   0   0  1011   0 
       17(v6)   --listen--          --any--           500   0   0 20011   0 
      Router#

  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)

  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)

  Products Confirmed Not Vulnerable

  Cisco IOS XE and Cisco IOS XR Software are not affected by this vulnerability. No other Cisco products are currently known to be affected by this vulnerability.

Details

• IPsec is an IP security feature that provides robust authentication and encryption of IP packets. IKE is a key management protocol standard that is used with the IPsec standard.

  IKE is a hybrid protocol that implements the Oakley and SKEME key exchanges inside the Internet Security Association and Key Management Protocol (ISAKMP) framework. (ISAKMP, Oakley, and SKEME are security protocols that are implemented by IKE.). More information on IKE is available at the following link:

  http://www.cisco.com/en/US/docs/ios/sec_secure_connectivity/configuration/guide/sec_key_exch_ipsec.html

  A vulnerability exists in the Cisco IOS Software implementation of IKE where a malformed packet may cause a device running Cisco IOS Software to reload. Only Cisco 7200 Series and Cisco 7301 routers running Cisco IOS software with a VPN Acceleration Module 2+ (VAM2+) installed are affected.

  This vulnerability is documented in Cisco Bug ID CSCtb13491 ( registered customers only) and has been assigned CVE ID CVE-2010-0578.

Workarounds

• There are no workarounds available.

Fixed Software

• 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 "Bundle First Fixed Release" column indicates the earliest possible releases which have fixes for all the published vulnerabilities in this Cisco IOS Security Advisory bundled publication. Cisco recommends upgrading to the latest available release where possible.
