Cisco Unified Communications Manager Express Denial of Service Vulnerabilities

Summary

• Devices running Cisco IOS^® Software and configured for Cisco Unified Communications Manager Express (CME) or Cisco Unified Survivable Remote Site Telephony (SRST) operation are affected by two denial of service vulnerabilities that may result in a device reload if successfully exploited. The vulnerabilities are triggered when the Cisco IOS device processes specific, malformed Skinny Call Control Protocol (SCCP) messages.

  Cisco has released software updates that address these vulnerabilities.

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

  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

• Cisco IOS devices, including Cisco Unified Communications 500 Series, that are configured for the Cisco Unified CME or the Cisco Unified SRST features are affected.

  Vulnerable Products

  A Cisco IOS device that is configured for Cisco Unified CME operation displays the following output when the show running-config command is issued:

  telephony-service
    ...
  !
  ephone 
    ...

  A Cisco IOS device that is configured for Cisco Unified SRST operation displays the following output when the show running-config command is issued:

  call-manager-fallback
    ...

  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 is displayed 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 XR Software is not affected.

  Cisco IOS XE Software is not affected.

  Cisco Unified Communications Manager is not affected.

  No other Cisco products are currently known to be affected by these vulnerabilities.

Details

• Cisco Unified CME is the call processing component of an enhanced IP telephony solution that is integrated into Cisco IOS Software. Cisco Unified SRST is a critical component of a centralized call-processing architecture in which a Cisco Unified Communications Manager cluster, located at a central site, provides telephony services for all sites of an organization.

  The Cisco Unified CME and Cisco Unified SRST features in Cisco IOS Software are affected by two denial of service (DoS) vulnerabilities that may cause a device reload when processing specific, malformed SCCP messages. The malformed SCCP messages can only come from registered phone IP addresses. If the auto-registration feature is enabled (Cisco Unified CME only), an attacker can register its IP address and subsequently send a malformed payload to exploit these vulnerabilities. The auto-registration feature is enabled by default. More information on auto-registration can be found at the following link:

  http://www.cisco.com/en/US/docs/voice_ip_comm/cucme/command/reference/cme_a1ht.html#wp1031242

  Exploitation of these vulnerabilities requires that a TCP three-way handshake to the SCCP port be completed. By default, the SCCP port is TCP port 2000, but this can be changed with the ip source-address command in telephony service configuration mode.

  These vulnerabilities are addressed by Cisco bug IDs CSCsz48614 ( registered customers only) and CSCsz49741 ( registered customers only) and have been assigned Common Vulnerabilities and Exposures (CVE) IDs CVE-2010-0585 and CVE-2010-0586, respectively.

Workarounds

• There are no workarounds for these vulnerabilities. However, in the case of the Cisco Unified CME feature, auto-registration can be disabled to make exploitation more difficult. Auto-registration can be disabled for the Cisco Unified CME feature by issuing the following commands:

  telephony-service
    no auto-reg-ephone

  Before disabling auto-registration, all phone MAC addresses need to be explicitly defined on the Cisco Unified CME. Otherwise phones will not be able to register. More information on auto-registration can be found at the following link:

  http://www.cisco.com/en/US/docs/voice_ip_comm/cucme/command/reference/cme_a1ht.html#wp1031242

  Additional mitigations that can be deployed on Cisco devices within the network are available in the companion document "Cisco Applied Mitigation Bulletin: Identifying and Mitigating Exploitation of the Cisco Unified Communications Manager Express and Cisco IOS Software H.323 and Session Initiation Protocol Denial of Service Vulnerabilities", which is available at the following location: http://tools.cisco.com/security/center/content/CiscoAppliedMitigationBulletin/cisco-amb-20100324-voice.

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 for this Advisory" column of the table. The "First Fixed Release for all Advisories in 24 March 2010 Bundle Publication" 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.
