      Revision 1.0
      
      For Public Release 2007 August 08 1600 UTC (GMT)
      
      - -----------------------------------------------------------------------
      
      Summary
      =======
      
      Multiple voice-related vulnerabilities are identified in Cisco IOS
      software, one of which is also shared with Cisco Unified Communications
      Manager. These vulnerabilities pertain to the following protocols or
      features:
      
        * Session Initiation Protocol (SIP)
        * Media Gateway Control Protocol (MGCP)
        * Signaling protocols H.323, H.254
        * Real-time Transport Protocol (RTP)
        * Facsimile reception
      
      Cisco has made free software available to address these vulnerabilities
      for affected customers. Fixed Cisco IOS software listed in the Software
      Versions and Fixes section contains fixes for all vulnerabilities
      mentioned in this advisory.
      
      There are no workarounds available to mitigate the effects of any of
      the vulnerabilities apart from disabling the protocol or feature
      itself.
      
      This advisory is posted at 
      http://www.cisco.com/warp/public/707/cisco-sa-20070808-IOS-voice.shtml.
      
      Note: The August 08, 2007 publication includes four Security Advisories
      and one Security Response. The advisories all affect IOS, one
      additionally affects Cisco Unified Communications Manager as well. Each
      advisory lists the releases that correct the vulnerability described in
      the advisory, and the advisories also detail the releases that correct
      the vulnerabilities in all four advisories. Individual publication

      Affected Products
      =================
      
      These vulnerabilities only affect devices running Cisco IOS that have
      voice services enabled. The only exception is the vulnerability
      documented as Cisco bug ID CSCsi80102, which also exists on Cisco 
      Unified Communications Manager.
      
      Vulnerable Products
      +------------------
      
      To determine the software running on a Cisco IOS product, log in to the
      device and issue the "show version" command to display the system banner.
      Cisco IOS software will identify itself as "Internetwork Operating
      System Software" or simply "IOS." On the next line of output, the image
      name will be displayed between parentheses, followed by "Version" and
      the Cisco IOS release name. Other Cisco devices will not have the 
      "show version" command, or will give different output.
      
      The following example shows output from a device running an IOS image:
      
          Router>show version
          Cisco IOS Software, 7200 Software (C7200-IK9S-M), Version 12.3(14)T1, RELEASE SOFTWARE (fc1)

      Additional information about Cisco IOS release naming is available at
      the following link:

      SIP-related vulnerabilities
      +--------------------------
      
      Any Cisco device that runs a vulnerable version of IOS and supports SIP
      processing could be vulnerable. This includes IOS versions 12.3(4)XH,
      12.3(4)XQ, 12.3(7)XR, 12.3(7)XS, 12.3(8)JA, 12.3(8)T, 12.3(8)XU, 12.3
      (8)XW, 12.3(8)XX, 12.3(8)XY, 12.3(8)YA, 12.3(8)YG, 12.3(8)YH, 12.3(8)
      YI, 12.3(8)ZA, 12.4 Mainline and 12.4T onward. Routers that are
      configured as SIP Public Switched Telephone Network (PSTN) Gateways and
      SIP Session Border Controllers (SBCs) are vulnerable. The CAT6000-CMM
      card is also vulnerable.
      
      To determine if the device has SIP enabled, enter the commands 
      "show ip sockets" and "show tcp brief all". In some newer IOS releases 
      the command "show ip sockets" is removed. If that is the case use "show udp". 
      The output is identical to the "show ip sockets" command.
      
          Router#show ip sockets
          Proto    Remote      Port      Local       Port  In Out Stat TTY OutputIF
          17 0.0.0.0             0  --any--          5060   0   0  211   0
          17 0.0.0.0             0 192.168.100.2       67   0   0 2211   0
          17 0.0.0.0             0 192.168.100.2     2517   0   0   11   0
      
      
      The first line with UDP Port 5060 shows that UDP SIP is enabled.
      
          Router#show tcp brief all
          TCB       Local Address           Foreign Address        (state)
          2051E680  *.5060                  *.*                    LISTEN
      
      
      The above lines with *.5060 show that TCP SIP is enabled.
      
      The device is vulnerable even if it does not have SIP explicitly
      configured. If the output of the "show ip sockets" command is showing
      that the device is listening to port 5060, then the device is
      vulnerable.
      
      MGCP-related vulnerabilities
      +---------------------------
      
      To determine whether MGCP is configured on an IOS device, look for
      either of the following lines in in the Cisco IOS configuration:
      
          Router#show running config
          ....
          voice-port 1/1/1
          !
          mgcp
          !
          dial-peer voice 1 pots
           service mgcpapp
           port 1/1/1
      
      
      or
      
          Router#show running config
          ....
          controller T1 1/1
           framing sf
           linecode ami
           pri-group timeslots 1-24 service mgcp
      
      
      or
      
          Router#show running config
          ....
          controller T1 1/1
           framing sf
           linecode ami
           ds0-group 0 timeslots 1-24 type none service mgcp
      
      
      The exact port numbers may vary in the configuration.
      
      H.323 signaling-related vulnerabilities
      +--------------------------------------
      
      To determine whether H.323 is configured on an IOS device, look for
      either of the following lines in the Cisco IOS configuration.
      
      For Cisco bug ID CSCsi60004 this configuration is vulnerable:
      
          Router#show running config | include proxy
          proxy h323
      
      
      For Cisco bug ID CSCsg70474 this configuration is vulnerable:
      
          Router#show running config | include inspect
          ip inspect name H323_protocol h323
           ip inspect H323_protocol in
      
      
      Real-time Transport Protocol-related vulnerabilities
      +---------------------------------------------------
      
      No particular configuration is required to enable RTP because this
      protocol is invoked when audio or video information is transmitted.
      H.323, MGCP, SIP, or H.320 protocols must be processing packets for a
      router to process RTP packets.
      
      Note: These vulnerabilities only affect sessions terminating or
      originating on a device itself, not transit traffic; for example,
      traffic that passes through a device, but is destined elsewhere is not
      affected.
      
      Facsimile reception vulnerability
      +--------------------------------
      
      The IOS device will listen to incoming facsimile transmission by
      default if the Digital Signal Processor (DSP) is present. To determine
      the presence of DSP on a device, execute the following command:
      
      Note: This vulnerability only affects sessions terminating or
      originating on a device itself, not transit traffic; for example,
      traffic that passes through a device, but is destined elsewhere is not
      affected.

      The above example shows that DSP is present on the device.
      
      Products Confirmed Not Vulnerable
      +--------------------------------
      
      No other Cisco products are currently known to be affected by these
      vulnerabilities. The following devices are known not to be affected:
      
        * Cisco Unified Communications Manager (with the exception of
          CSCsi80102)
        * Cisco IP Phone
      
      Details
      =======
      
      Details for vulnerabilities are grouped by category and impact.
      
      SIP-related vulnerabilities
      +--------------------------
      
      SIP is a protocol that is used to establish, modify, and terminate
      multimedia sessions. Most commonly, SIP is used for Internet telephony.
      SIP call signaling can use UDP (User Datagram Protocol) or TCP
      (Transport Control Protocol) as an underlying transport protocol. In
      all cases vulnerabilities can be triggered by processing a malformed
      SIP packet.
      
      A malformed SIP packet may cause a vulnerable device to crash and may
      allow arbitrary code to be executed. These vulnerabilities are
      documented as the following Cisco Bug IDs:
      
        * CSCsi80749 Crash while processing malformed SIP packet
        * CSCsi80102 CUCM - Crash while processing malformed SIP packet 
      
      A malformed SIP packet may cause a memory leak and device crash. These
      vulnerabilities are documented as the following Cisco Bug IDs:
      
        * CSCsf11855 Crash while processing malformed SIP packet 
        * CSCeb21064 Crash while processing malformed SIP packet
        * CSCse40276 Router crashed by malformed SIP message 
        * CSCse68355 Router crashed by malformed SIP packet 
        * CSCsf30058 Memory leak when processing malformed SIP message 
        * CSCsb24007 Memory corruption and unexpected reload on receiving a
          SIP packet 
        * CSCsc60249 Crash while processing malformed SIP packet 
      
      MGCP-related vulnerabilities
      +---------------------------
      
      MGCP is a protocol for controlling media gateways from external call
      control elements such as Media Gateway Controllers or Call Agents. A
      media gateway is typically a network element that provides conversion
      between the audio signals carried on telephone circuits and data
      packets carried over the Internet or over other packet networks. In a
      Cisco environment, a media gateway is used between the Cisco
      Communications Manager and the Cisco router and servers as a voice
      gateway.
      
      A specially crafted MGCP packet can cause a vulnerable device to crash
      or become unresponsive. The unresponsive device will not be able to
      establish new telephone calls, and a reboot is required to restore
      normal operation. These vulnerabilities are documented as the following
      Cisco Bug IDs:
      
        * CSCsf08998 MGCP stop responding after receiving malformed packet 
        * CSCsd81407 Router crash on receiving abnormal MGCP messages 
      
      H.323-signaling related vulnerabilities
      +--------------------------------------
      
      H.323 is an ITU (International Telecommunications Union) set of
      recommendations for multimedia communication and signaling in networks
      that use Internet Protocol.
      
      A malformed H.323 packet can crash a vulnerable device. These
      vulnerabilities are documented as the following Cisco Bug IDs:
      
        * CSCsi60004 H323 Proxy Unregistration from Gatekeeper 
        * CSCsg70474 IOS FW with h323 inspect crashes when malformed H.323
          packets received 
      
      Real-time Transport Protocol-related vulnerabilities
      +---------------------------------------------------
      
      RTP is a protocol that is designed to provide delivery services for
      data with real-time characteristics, such as interactive audio and
      video.
      
      A malformed RTP packet can cause a vulnerable device to crash. These
      vulnerabilities are documented as the following Cisco Bug IDs:
      
        * CSCse68138 Issue in handling specific packets in VOIP RTP Lib 
        * CSCse05642 I/O memory corruption crash on a router 
      
      Facsimile reception vulnerability
      +--------------------------------
      
      Reception of a large packet can cause a vulnerable device to crash.
      This vulnerability is documented as the following Cisco Bug ID:
      
        * CSCej20505 Router hangs with overly large packet 
      
      Vulnerability Scoring Details
      +----------------------------
      
      Cisco is providing 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 1.0.
      
      Cisco will provide a base and temporal score. Customers can then
      compute environmental scores to assist in determining the impact of the
      vulnerability in individual networks.
      
      Cisco PSIRT will set the bias in all cases to normal. Customers are
      encouraged to apply the bias parameter when determining the
      environmental impact of a particular vulnerability.
      
      CVSS is a standards-based scoring method that conveys vulnerability
      severity and helps determine urgency and priority of response.
      
      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.
      
      Note:  To make this document more readable, individual CVSS scores for
      vulnerabilities are not shown. Instead, the vulnerabilities are grouped
      according to the score.

      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.

      maintained, please see the following URL:

      Workarounds
      ===========
      
      None of the listed vulnerabilities have workarounds. Users are advised
      to apply mitigation techniques to limit exposure to the listed
      vulnerabilities. Mitigation consists of only allowing legitimate
      devices to connect to the routers. To increase effectiveness, the
      mitigation must be coupled with the application of anti-spoofing
      measures on the network edge. This action is required because all
      vulnerable voice protocols can use UDP as transport protocol.
      
      None of the listed vulnerabilities can be mitigated on Cisco Unified
      Communications Manager. All mitigations must be done on adjacent
      devices.
      
      Users are advised to disable affected protocols if not required for
      normal device operation. To prevent the router from processing SIP
      packets, the user must execute the following commands:
      
          Router(config)#sip-ua
          Router(config-sip-ua)#no transport udp
          Router(config-sip-ua)#no transport tcp
          Router(config-sip-ua)#end
      
      
      
      Note:  When applying this workaround to devices that are processing
      MGCP or H.323 calls, the device will not allow SIP processing to stop
      while active calls are being processed. As a result, the workaround
      should be implemented during a maintenance period when active calls can
      be stopped.
      
      Infrastructure Access Control Lists (iACL)
      +-----------------------------------------
      
      Although difficult to block traffic from transiting the network, it is
      possible to identify traffic that should not target infrastructure
      devices and block such traffic at the network border. Infrastructure
      ACLs are considered a network security best practice and should be
      considered as a long-term addition to good network security as well as
      a workaround for this specific vulnerability. The ACL example shown
      below should be included as part of the deployed infrastructure access
      list that will protect all devices with IP addresses located within the
      infrastructure IP address range.
      
      A sample access list for devices running Cisco IOS is below:
      
      
          !-- Permit SIP, MGCP, H.323 and RTP services from trusted hosts destined
          !-- to infrastructure addresses.
      
          access-list 150 permit tcp TRUSTED_HOSTS MASK INFRASTRUCTURE_ADDRESSES MASK eq 5060
          access-list 150 permit tcp TRUSTED_HOSTS MASK INFRASTRUCTURE_ADDRESSES MASK eq 5061
          access-list 150 permit udp TRUSTED_HOSTS MASK INFRASTRUCTURE_ADDRESSES MASK eq 5060
          access-list 150 permit udp TRUSTED_HOSTS MASK INFRASTRUCTURE_ADDRESSES MASK eq 5061
          access-list 150 permit udp TRUSTED_HOSTS MASK INFRASTRUCTURE_ADDRESSES MASK eq 2427
          access-list 150 permit tcp TRUSTED_HOSTS MASK INFRASTRUCTURE_ADDRESSES MASK eq 1720
          access-list 150 permit tcp TRUSTED_HOSTS MASK INFRASTRUCTURE_ADDRESSES MASK eq 11720
          access-list 150 permit udp TRUSTED_HOSTS MASK INFRASTRUCTURE_ADDRESSES MASK eq 2517
          access-list 150 permit udp TRUSTED_HOSTS MASK INFRASTRUCTURE_ADDRESSES MASK range 16384 32767
      
          !-- Deny SIP, MGCP, H.323 and RTP packets from all other sources destined
          !-- to infrastructure addresses.
      
          access-list 150 deny tcp any INFRASTRUCTURE_ADDRESSES MASK eq 5060
          access-list 150 deny tcp any INFRASTRUCTURE_ADDRESSES MASK eq 5061
          access-list 150 deny udp any INFRASTRUCTURE_ADDRESSES MASK eq 5060
          access-list 150 deny udp any INFRASTRUCTURE_ADDRESSES MASK eq 5061
          access-list 150 deny udp any INFRASTRUCTURE_ADDRESSES MASK eq 2427
          access-list 150 deny tcp any INFRASTRUCTURE_ADDRESSES MASK eq 1720
          access-list 150 deny tcp any INFRASTRUCTURE_ADDRESSES MASK eq 11720
          access-list 150 deny udp any INFRASTRUCTURE_ADDRESSES MASK eq 2517
          access-list 150 deny udp any INFRASTRUCTURE_ADDRESSES MASK range 16384 32767
      
          !-- Permit all other traffic to transit the device.
      
          access-list 150 permit ip any any
          interface serial 2/0
           ip access-group 150 in
      
      
      The white paper entitled "Protecting Your Core: Infrastructure
      Protection Access Control Lists" presents guidelines and recommended
      deployment techniques for infrastructure protection access lists. This
      white paper can be obtained at the following link: 
      http://www.cisco.com/warp/public/707/iacl.html.
      
      Control Plane Policing
      +---------------------
      
      Control Plane Policing (CoPP) can be used to block untrusted SIP (TCP
      and UDP ports 5060 and 5061), MGCP (UDP port 2427), H.323 (TCP ports
      1720 and 11720 and UDP port 2517), and RTP (UDP ports 16384 to 32767)
      access to the device. Cisco IOS software releases 12.0S, 12.2SX, 12.2S,
      12.3T, 12.4, and 12.4T support the CoPP feature. CoPP may be configured
      on a device to protect the management and control planes to minimize
      the risk and effectiveness of direct infrastructure attacks. CoPP
      protects the management and control planes by explicitly permitting
      only authorized traffic sent to infrastructure devices and in
      accordance with existing security policies and configurations. The
      following example, which uses 192.168.100.1 to represent a trusted
      host, can be adapted to the network:
      
      
          !-- Deny SIP, MGCP, H.323 and RTP traffic from trusted hosts to all
          !-- IP addresses configured on all interfaces of the affected device
          !-- so that it will be allowed by the CoPP feature.
      
          access-list 111 deny tcp host 192.168.100.1 any eq 5060
          access-list 111 deny tcp host 192.168.100.1 any eq 5061
          access-list 111 deny udp host 192.168.100.1 any eq 5060
          access-list 111 deny udp host 192.168.100.1 any eq 5061
          access-list 111 deny udp host 192.168.100.1 any eq 2427
          access-list 111 deny tcp host 192.168.100.1 any eq 1720
          access-list 111 deny tcp host 192.168.100.1 any eq 11720
          access-list 111 deny udp host 192.168.100.1 any eq 2517
          access-list 111 deny udp host 192.168.100.1 any range 16384 32767
      
          !-- Permit all other SIP, MGCP, H.323 and RTP traffic sent to all
          !-- IP addresses configured on all interfaces of the affected device
          !-- so that it will be policed and dropped by the CoPP feature.
      
          access-list 111 permit tcp any any eq 5060
          access-list 111 permit tcp any any eq 5061
          access-list 111 permit udp any any eq 5060
          access-list 111 permit udp any any eq 5061
          access-list 111 permit udp any any eq 2427
          access-list 111 permit tcp any any eq 1720
          access-list 111 permit tcp any any eq 11720
          access-list 111 permit udp any any eq 2517
          access-list 111 permit udp any any range 16384 32767
      
          !-- Permit (Police or Drop)/Deny (Allow) all other Layer 3 and Layer 4
          !-- traffic in accordance with existing security policies and
          !-- configurations for traffic that is authorized to be sent
          !-- to infrastructure devices.
      
          !-- Create a Class-Map for traffic to be policed by
          !-- the CoPP feature.
      
          class-map match-all drop-voice-class
            match access-group 111
      
          !-- Create a Policy-Map that will be applied to the
          !-- Control-Plane of the device.
      
          policy-map drop-voice-traffic
            class drop-voice-class
                  drop
      
          !-- Apply the Policy-Map to the Control-Plane of the
          !-- device.
      
          control-plane
            service-policy input drop-voice-traffic
      
      
      In the above CoPP example, the access control list entries (ACEs) that
      match the potential exploit packets with the "permit" action result in
      the exploit packets being discarded by the policy-map "drop" function.
      Meanwhile, packets that match the "deny" action (not shown) are not
      affected by the policy-map drop function.
      
      Please note that in the 12.2S and 12.0S Cisco IOS trains the policy-map
      syntax is different:

      Obtaining Fixed Software
      ========================
      
      Cisco will make free software available to address these
      vulnerabilities for affected customers. This advisory will be updated
      as fixed software becomes available. 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/public/sw-license-agreement.html, or as otherwise 
      set forth at Cisco.com Downloads at 
      http://www.cisco.com/public/sw-center/sw-usingswc.shtml.
      
      Do not contact either "psirt at cisco dot com" or "security-alert at cisco dot 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 agreement 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 who do not hold a Cisco
      service contract and customers who purchase through third-party vendors
      but are unsuccessful at obtaining fixed software through their point of
      sale should get their 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 at cisco dot com
      
      Have your product serial number available and give the URL of this
      notice as evidence of your entitlement to a free upgrade. Free upgrades
      for non-contract customers must be requested through the TAC.
      
      Refer to http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml
      for additional TAC contact information, including special localized
      telephone numbers and instructions and e-mail addresses for use in
