      Summary
      =======
      
      A vulnerability in the handling of IP sockets can cause devices to be
      vulnerable to a denial of service attack when any of several features
      of Cisco IOS  Software are enabled. A sequence of specially crafted
      TCP/IP packets could cause any of the following results:
      
        * The configured feature may stop accepting new connections or
          sessions.
        * The memory of the device may be consumed.
        * The device may experience prolonged high CPU utilization.
        * The device may reload.
      
      Cisco has released free software updates that address this
      vulnerability.
      
      Several mitigation strategies are outlined in the "Workarounds"
      section of this advisory.

      Affected Products
      =================
      
      Vulnerable Products
      +------------------
      
      Devices that are running affected versions of Cisco IOS Software and
      Cisco IOS XE Software are affected if they are running any of the
      following features. Details about confirming whether the affected
      feature is enabled on a device are in the "Details" section of this
      advisory.
      
        * Cisco Unified Communications Manager Express
        * SIP Gateway Signaling Support Over Transport Layer Security (TLS)
          Transport
        * Secure Signaling and Media Encryption
        * Blocks Extensible Exchange Protocol (BEEP)
        * Network Admission Control HTTP Authentication Proxy
        * Per-user URL Redirect for EAPoUDP, Dot1x, and MAC Authentication
          Bypass
        * Distributed Director with HTTP Redirects
        * DNS (TCP mode only)
      
      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)

      Products Confirmed Not Vulnerable
      +--------------------------------
      
      The following product is not affected by this vulnerability:
      
        * Cisco IOS XR Software
      
      No other Cisco products or features configured in Cisco IOS or Cisco
      IOS XE Software are currently known to be affected by this
      vulnerability.
      
      Details
      ========
      
      For successful exploitation of this vulnerability, the TCP three-way
      handshake must be completed to the associated TCP port number(s) for
      any of the features described in this section.
      
      Cisco Unified Communications Manager Express
      +-------------------------------------------
      
      The following configurations are vulnerable for different Cisco
      Unified Communications Manager Express services:
      
      A certificate authority proxy function (CAPF) server has been
      configured.
      
      The following example shows a vulnerable CAPF server configuration:
      
          capf-server
           auth-mode null-string
           cert-enroll-trustpoint root password 1 104D000A061843595F
           trustpoint-label cme_cert
           source-addr 10.0.0.1
      
      The default TCP port used for CAPF server is 3804.
      
      Further information about CAPF-server is in the Cisco Unified
      Communications Manager Express System Administrator Guide at 
      http://www.cisco.com/en/US/docs/voice_ip_comm/cucme/admin/configuration/guide/cmeauth.html#wp1085744
      
      Telephony-service security parameters have been configured.
      
      If the telephony-service security parameters have been configured
      with "device-security-mode", the device is vulnerable. The following
      example shows three vulnerable configurations for telephony-service
      security parameters:
      
          ephone 1
           device-security-mode encrypted
      
          ephone 2
           device-security-mode authenticated
      
          ephone 3
           device-security-mode none
      
      The TCP port used is defined with the "ip source-address <address>
      port <port-number>" telephony-service configuration command.
      
      Further information about Telephony-service security parameters is in
      the Cisco Unified Communications Manager Express System Administrator
      Guide at 
      http://www.cisco.com/en/US/docs/voice_ip_comm/cucme/admin/configuration/guide/cmeauth.html#wp1080079
      
      The global telephony-service or call-manager-fallback command has
      been configured.
      
      Any Cisco IOS configuration with the global "telephony-service" or
      "call-manager-fallback" command is vulnerable if any subcommands are
      in the telephony-service or call-manager-fallback configuration mode.
      The following examples show vulnerable configurations:
      
          telephony-service
           ip source-address 192.168.0.1 port 2011
      
      or
      
          call-manager-fallback
           ip source-address 192.168.0.1 port 2011
      
      The TCP port used is defined with the "ip source-address <address>
      port <port-number>" configuration command.
      
      Further information about telephony service and call-manager-fallback
      is in the Cisco Unified Communications Manager Express System
      Administrator Guide at 
      http://www.cisco.com/en/US/docs/voice_ip_comm/cucme/admin/configuration/guide/cmesystm.html
      
      SIP Gateway Signaling Support over TLS Transport
      +----------------------------------------------
      
      Note: For customers with devices enabled with SIP, also consult the
      document "Cisco Security Advisory: Cisco IOS Session Initiation
      Protocol Denial of Service Vulnerability" at the following link 
      http://www.cisco.com/warp/public/707/cisco-sa-20090325-sip.html
      
      Devices that are configured for SIP gateway signaling support over
      TLS transport are vulnerable. The following examples show vulnerable
      configurations:
      
          voice service voip
           sip
            session transport tcp tls
            url sips
      
      - -- or --
      
          dial-peer voice 3456 voip
           voice-class sip url sips
           session protocol sipv2
           session transport tcp tls
      
      For the SIP gateway signaling support over TLS transport to function
      correctly, administrators must first configure a trustpoint using the
      following configuration:
      
          sip-ua
               crypto signaling default trustpoint example_trustpoint_name
      
      The default TCP port used for the SIP gateway signaling support over
      TLS transport feature is 5061.
      
      Further information about Cisco IOS SIP gateway signaling support
      over TLS transport is in the Cisco IOS Software Release 12.4T feature
      guide at 
      http://www.cisco.com/en/US/docs/ios/12_4t/12_4t11/FeatTLS.html
      
      Secure Signaling and Media Encryption
      +------------------------------------
      
      A device is vulnerable if it is configured with the Media and
      Signaling Encryption (SRTP/TLS) on DSP Farm Conferencing feature or
      with Secure Signaling and Media Encryption for analog phones with
      Skinny Call Control Protocol (SCCP).
      
      The following examples show three different vulnerable secure DSP
      farm configurations. Several other parts are required for a full
      configuration, such as certificates and SCCP configuration, but these
      parts have been excluded for brevity.
      
          dspfarm profile 2 transcode security

           codec g711ulaw
           codec g711alaw
           codec g729ar8
           codec g729abr8
           codec g729r8
           codec g729br8
           maximum sessions 2

          dspfarm profile 5 mtp security
           trustpoint 2851ClientMina
           codec g711alaw
           maximum sessions hardware 1
           associate application SCCP
      
      The default TCP port used for the Media and Signaling Encryption on
      DSP Farm Conferencing feature is 2443.
      
      Further information about the Media and Signaling Encryption on DSP
      Farm Conferencing feature is in the "Cisco IOS Software Release 12.4
      Special and Early Deployments feature guide" at the following link
      http://www.cisco.com/en/US/docs/ios/12_4t/12_4t15/itsdsp.html
      
      The following output shows the relevant section of Secure Signaling
      and Media Encryption for analog phones and is a vulnerable
      configuration (Several other parts are required for a full
      configuration, such as certificates, SCCP configuration, and dial
      peers):
      
      
          !--- The following lines show SCCP Telephony Control Application 
          !--- (STCAPP) security enabled at the system level:
      
          stcapp ccm-group 1
          stcapp security trustpoint analog
          stcapp security mode encrypted
          stcapp

          dial-peer voice 5002 pots
          service stcapp
      
          !--- The following line shows the security mode configured on the 
          !--- dial peer.
      
          security mode authenticated
          port 2/1
      
      The default TCP port used for Media and Signaling Encryption for
      analog phones is 2443.
      
      Further information about Media and Signaling Encryption for analog
      phones is in the "Supplementary Services Features for FXS Ports on
      Cisco IOS Voice Gateways Configuration Guide, Release 12.4T" at the
      following link 
      http://www.cisco.com/en/US/docs/ios/voice/fxs/configuration/guide/fsxsecur.html
      
      Blocks Extensible Exchange Protocol
      +----------------------------------
      
      Any configuration or executable command that leverages Blocks
      Extensible Exchange Protocol (BEEP) as a transport protocol is
      vulnerable. The following example shows the vulnerable configuration
      of the feature NETCONF over BEEP. NETCONF over BEEP using SASL is
      also vulnerable.
      
          crypto key generate rsa general-keys
          crypto pki trustpoint my_trustpoint
          enrollment url http://10.2.3.3:80
          subject-name CN=dns_name_of_host.com
          revocation-check none
      
          crypto pki authenticate my_trustpoint
          crypto pki enroll my_trustpoint
      
          line vty 0 15
          netconf lock-time 60
          netconf max-sessions 16
      
          netconf beep initiator host1 23 user my_user password
             my_password encrypt my_trustpoint
          reconnect-time 60
      
          netconf beep listener 23 sasl user1 encrypt my_trustpoint
      
      The TCP port used is defined with the "netconf beep initiator" and
      "netconf beep listener" configuration commands.
      
      Further information about NETCONF over BEEP is in the "Cisco IOS
      Software Release 12.4T feature guide" at the following link 
      http://www.cisco.com/en/US/docs/ios/12_4t/12_4t11/htnetbe.html#wp1049404
      
      The BEEP executable commands "bingd" and "bingng" could cause this
      vulnerability to be triggered when they are invoked. The following
      shows an example of these commands being executed:
      
          bingng device 192.168.0.1 23
          bingd device 23
      
      Network Admission Control HTTP Authentication Proxy
      +--------------------------------------------------
      
      Devices configured with Network Admission Control HTTP Authentication
      Proxy are vulnerable. For the device to be vulnerable the
      authentication proxy rule must exist and be applied to an interface.
      
      The following configuration creates an authentication proxy rule.
      
          ip admission name example-ap-rule-name proxy http
      
      The following configuration attaches the authentication proxy rule
      (created in the previous example) to an interface.
      
          interface GigabitEthernet 0/0
           ip admission example-ap-rule-name
      
      The default TCP port used for Network Admission Control HTTP
      Authentication Proxy is 80.
      
      Further information about Network Admission Control HTTP
      Authentication Proxy is in the "Cisco IOS Security Configuration
      Guide, Release 12.4" at the following link 
      http://www.cisco.com/en/US/docs/ios/security/configuration/guide/sec_net_admssn_ctrl_ps6350_TSD_Products_Configuration_Guide_Chapter.html#wp1053957
      
      Per-user URL Redirect for EAPoUDP, Dot1x, and MAC Authentication Bypass
      +----------------------------------------------------------------------
      
      Devices that have URL redirect feature configured are vulnerable. URL
      redirect is supported for EAP over UDP (EAPoUDP), Dot1x and MAC
      Authentication Bypass (MAB) authentication mechanisms. The URL
      redirect configuration can either be on the server or set up as part
      of a locally defined profile or policy. Both configurations are
      vulnerable. A device is vulnerable with either of the following
      configurations.
      
      URL Redirect Feature Enabled for EAPoUDP
      +---------------------------------------
      
      The URL redirect feature is enabled for EAPoUDP with the following
      global configuration command:
      
          ip admission name <EAPoUDP-rule-name> eapoudp
      
      The following configuration attaches the EAPoUDP rule (created in the
      previous example) to an interface.
      
          ip admission name <EAPoUDP-rule-name>
      
      URL Redirect Feature Enabled for Dot1x and MAB
      +---------------------------------------------
      
      The URL redirect feature for both Dot1x and MAB are vulnerable and
      will have a URL redirect AV pair on the RADIUS server defined in a
      method that is similar to the following:
      
          url-redirect="http://example.com";
          url-redirect="urlacl"
      
      For the Dot1x and MAB URL redirect feature to work successfully on
      the switch, the minimum following configuration would also be
      required. There is no interface-specific configuration for URL
      redirect. Basically the interface has to be configured for Dot1x/MAB.
      
          ip http {server | secure-server}
          ip device tracking
      
      The default TCP port used for per-user URL redirect for EAPoUDP,
      Dot1x, and MAB is 80 and 443.
      
      Further information about per-user URL redirect for EAPoUDP, Dot1x,
      and MAB is in the "Catalyst 4500 Series Switch Software Configuration
      Guide, 12.2(50)SG" at the following link 
      http://www.cisco.com/en/US/docs/switches/lan/catalyst4500/12.2/50sg/configuration/guide/dot1x.html#wp1311079
      
      Distributed Director with HTTP Redirects
      +---------------------------------------
      
      A device is vulnerable if Distributed Director is configured with
      HTTP redirects. The following example shows a vulnerable
      configuration:
      
          ip director ip-address 192.168.0.1
      
      The default TCP port used for distributed director with HTTP redirect
      is 53.

      DNS
      +--
      
      Devices that are configured with the Cisco IOS DNS feature are
      vulnerable. A pure DNS over UDP implementation is not vulnerable. See
      the "Workarounds" section of this advisory for information about
      filtering DNS over TCP traffic to the device. If any of the commands
      in the following example appear in the device configuration, the
      device is vulnerable:
      
          ip dns server
          ip dns primary example.com soa www.example.com admin at example dot com
          ip dns spoofing 192.168.0.1
      
      The default TCP port used for DNS is 53.
      
      Further information about Cisco IOS DNS is in the "Cisco IOS IP
      Addressing Services Configuration Guide, Release 12.4" at the
      following link

      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

      Impact
      ======
      
      Successful exploitation of the vulnerability may result in the any of
      the following occurring:
      
        * The configured feature may stop accepting new connections or
          sessions.
        * The memory of the device may be consumed.
        * The device may experience prolonged high CPU utilization.
        * The device may reload.
      
      Repeated attempts to exploit this vulnerability could result in a
      sustained 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.

      Workarounds
      ===========
      
      The following mitigations have been identified for this
      vulnerability:
      
      Infrastructure Access Control Lists
      +----------------------------------
      
      Although it is often difficult to block traffic that transits a
      network, it is possible to identify traffic that should never be
      allowed to target infrastructure devices and block that traffic at
      the border of networks. Infrastructure Access Control Lists (iACLs)
      are a network security best practice and should be considered as a
      long-term addition to good network security as well as a workaround
      for these specific vulnerabilities. The iACL example below should be
      included as part of the deployed infrastructure access-list which
      will protect all devices with IP addresses in the infrastructure IP
      address range:

          !--- need be configured.

      The white paper entitled "Protecting Your Core: Infrastructure
      Protection Access Control Lists" presents guidelines and recommended
      deployment techniques for infrastructure protection access lists.

      Receive ACLs (rACL)
      +------------------
      
      For distributed platforms, Receive ACLs may be an option starting in
      Cisco IOS Software Versions 12.0(21)S2 for the 12000 (GSR), 12.0(24)S
      for the 7500, and 12.0(31)S for the 10720. The Receive ACL protects
      the device from harmful traffic before the traffic can impact the
      route processor. Receive ACLs are designed to only protect the device
      on which it is configured. On the 12000, 7500, and 10720, transit
      traffic is never affected by a receive ACL. Because of this, the
      destination IP address "any" used in the example ACL entries below
      only refer to the router's own physical or virtual IP addresses.
      Receive 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 white paper entitled "GSR: Receive Access Control Lists" will
      help you identify and allow legitimate traffic to your device and
      deny all unwanted packets. This white paper is available at the
      following link 
      http://www.cisco.com/en/US/tech/tk648/tk361/technologies_white_paper09186a00801a0a5e.shtml

      Control Plane Policing
      +---------------------
      
      Control Plane Policing (CoPP) can be used to block the affected
      features TCP traffic 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 can be configured on a device to protect the
      management and control planes and minimize the risk and effectiveness
      of direct infrastructure attacks by explicitly permitting only
      authorized traffic that is sent to infrastructure devices in
      accordance with existing security policies and configurations. The
      CoPP example below should be included as part of the deployed CoPP
      which will protect all devices with IP addresses in the
      infrastructure IP address range.

      that match the potential exploit packets with the "permit" action
      result in these packets being discarded by the policy-map "drop"
      function, while packets that match the "deny" action (not shown) are
      not affected by the policy-map drop function. Please note that the
      policy-map syntax is different in the 12.2S and 12.0S Cisco IOS
      trains:
      
          policy-map drop-tcpip-traffic
            class drop-tcpip-class
              police 32000 1500 1500 conform-action drop exceed-action drop

      +------------------------------------------------
      
      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.
      
      Customers without Service Contracts
      +----------------------------------
      
      Customers who purchase direct from Cisco but do not hold a Cisco
      service contract, and customers who purchase through third-party
      vendors but are unsuccessful in obtaining fixed software through
      their point of sale should acquire upgrades by contacting the Cisco
      Technical Assistance Center (TAC). TAC contacts are as follows.
      
        * +1 800 553 2447 (toll free from within North America)
