      Cisco Security Advisory: Cisco IOS Software Multicast Source Discovery
      Protocol Vulnerability
      
      Advisory ID: cisco-sa-20120328-msdp
      
      Revision 1.0
      
      For Public Release 2012 March 28 16:00  UTC (GMT)
      
      +--------------------------------------------------------------------
      
      Summary
      =======
      
      A vulnerability in the Multicast Source Discovery Protocol (MSDP)
      implementation of Cisco IOS Software and Cisco IOS XE Software could
      allow a remote, unauthenticated attacker to cause a reload of an
      affected device. Repeated attempts to exploit this vulnerability could
      result in a sustained denial of service (DoS) condition.
      
      Cisco has released free software updates that address this
      vulnerability. Workarounds that mitigate this vulnerability are
      available. This advisory is available at the following link:
      
      http://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20120328-msdp
      
      
      Note: The March 28, 2012, Cisco IOS Software Security Advisory bundled
      publication includes nine Cisco Security Advisories. Each advisory
      lists the Cisco IOS Software releases that correct the vulnerability
      or vulnerabilities detailed in the advisory as well as the Cisco IOS
      Software releases that correct all vulnerabilities in the March 2012
      bundled publication.

      Affected Products
      =================
      
      Vulnerable Products
      +------------------
      
      The following products are affected by this vulnerability:
      
            + Cisco IOS Software
            + Cisco IOS XE Software
      
      To determine whether a Cisco IOS or Cisco IOS XE Software release 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 12.4(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)

      Cisco products are currently known to be affected by this vulnerability.
      
      Details
      =======
      
      MSDP is the protocol used to connect multiple Protocol Independent
      Multicast sparse mode (PIM-SM) domains. MSDP allows multicast sources
      for a group to be known to all rendezvous points (RPs) in different
      domains. An RP runs MSDP over TCP to discover multicast sources.
      
      An RP in a PIM-SM domain has an MSDP peering relationship with
      MSDP-enabled routers in another domain. The peering relationship occurs
      over a TCP connection, where primarily a list of sources sending to
      multicast groups is exchanged. The TCP connections between RPs are
      achieved by the underlying routing system. The receiving RP uses the
      source lists to establish a source path.
      
      The purpose of this topology is to have domains discover multicast
      sources in other domains. If the multicast sources are of interest to a
      domain that has receivers, multicast data is delivered over the normal,
      source-tree building mechanism in PIM-SM.
      
      An MSDP packet containing encapsulated Internet Group Management
      Protocol (IGMP) data, received from an external MSDP-configured peer
      router, can cause an affected device to reload. This vulnerability can
      only be exploited if the router is explicitly joined to the multicast
      group. The MSDP packet destination address is a unicast address and
      can be addressed to any IP address on the affected device, including
      loopback addresses.
      
      Transit traffic will not trigger this vulnerability.
      
      A vulnerable interface configuration contains an explicitly joined
      multicast group. Some example configurations that permit exploitation of
      this vulnerability are:
      
      
      !--- Interface configured for SAP Listener Support (a common
      multicast group)
      
      
      interface GigabitEthernet0/0
      ip address 192.168.0.1 255.255.255.0
      ip pim sparse-mode
      ip sap listen
      
      
      !--- Interface configured to join a multicast group
      
      interface GigabitEthernet0/0
      ip address 192.168.0.1 255.255.255.0
      ip pim sparse-mode
      ip igmp join-group 224.2.127.254
      
      
      You can also use the "show igmp interface" command to determine if an
      interface is joined to a multicast group.
      
          RouterA#show ip igmp interface 
          GigabitEthernet0/0 is up, line protocol is up
            Internet address is 192.168.0.1/24

            Current IGMP router version is 2
            IGMP query interval is 60 seconds
            IGMP querier timeout is 120 seconds
            IGMP max query response time is 10 seconds
            Last member query count is 2
            Last member query response interval is 1000 ms
            Inbound IGMP access group is not set
            IGMP activity: 2 joins, 0 leaves

      * Cisco Catalyst 3550 Series Switches support the Internet Key Exchange
      (IKE) feature and are vulnerable to Cisco bug ID CSCts38429 when the
      devices are running Layer 3 images; however, this product reached
      the End of Software Maintenance milestone. Cisco 3550 Series SMI
      Switches that are running Layer 2 images do not support IKE and are not
      vulnerable. No other Cisco devices that run 12.2SE-based software are
      vulnerable.

      Workarounds
      ===========
      
      Customers with an MSDP-configured router who do not require membership
      to multicast groups can remove the "ip sap listen" or "ip igmp
      join-group <multicast-group address>" commands on the router interface
      as a workaround.
      
      For example:
      
        RouterA#conf t
          RouterA(config)# interface GigabitEthernet0/0
          RouterA(config-if)# no ip sap listen
          RouterA(config-if)# no ip igmp join-group 224.2.127.254
      
      
        interface GigabitEthernet0/0
        ip address 192.168.0.1 255.255.255.0
        ip pim sparse-mode
      
      
      To determine if a router is configured for MSDP peers, run the
      command "show ip msdp peer" at the router command prompt:
      
          RouterA# show ip msdp peer
          MSDP Peer 192.168.0.2 (?), AS 100
            Connection status:
              State: Up, Resets: 0, Connection source: none configured
              Uptime(Downtime): 01:23:42, Messages sent/received: 25/24
              Output messages discarded: 0
              Connection and counters cleared 01:15:14 ago
            SA Filtering:
              Input (S,G) filter: none, route-map: none
              Input RP filter: none, route-map: none
              Output (S,G) filter: none, route-map: none
              Output RP filter: none, route-map: none
            SA-Requests:
              Input filter: none
            Peer ttl threshold: 0
            SAs learned from this peer: 0
              Input queue size: 0, Output queue size: 0
            Message counters:
              RPF Failure count: 0
              SA Messages in/out: 13/8

              SA Responses out: 0   
              Data Packets in/out: 7/8
      
      To remove an untrusted MSDP peer from your configuration, use the "no
      ip msdp peer <address>" or "ip msdp default-peer <ip-address | name>"
      command on the router configuration interface.
      
      RouterA(config)# no ip msdp peer 192.168.0.2
      
          interface GigabitEthernet0/0
           ip address 192.168.0.1 255.255.255.0
           ip pim sparse-mode
      
      
      Obtaining Fixed Software
      ========================
      
      Cisco has released free software updates that address the
      vulnerability|vulnerabilities described in this advisory. Prior to
      deploying software, customers are advised to consult their
      maintenance providers or check the software for feature set
      compatibility and known issues that are specific to their
      environments.
      
      Customers may only install and expect support for feature
      sets they have purchased. By installing, downloading,
      accessing, or otherwise using such software upgrades, customers
      agree to follow the terms of the Cisco software license at
      http://www.cisco.com/en/US/docs/general/warranty/English/EU1KEN_.html,
      or as set forth at
      http://www.cisco.com/public/sw-center/sw-usingswc.shtml.
      
      Do not contact 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, upgrades should be obtained
      through the Software Center on Cisco.com at http://www.cisco.com.
      
      Customers Using Third-Party Support Organizations
      +------------------------------------------------
      
      Customers with Cisco products that 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 organization for assistance with the appropriate
      course of action.
      
      The effectiveness of any workaround or fix depends on specific
      customer situations, such as product mix, network topology, traffic
      behavior, and organizational mission. Because of the variety of
      affected products and releases, customers should consult their
      service providers or support organizations to ensure that any applied
      workaround or fix is the most appropriate in the intended network
      before it is deployed.
      
      Customers Without Service Contracts
      +----------------------------------
      
      Customers who purchase directly from Cisco but do not hold a Cisco
      service contract and customers who make purchases through third-party
      vendors but are unsuccessful in obtaining fixed software through
      their point of sale should obtain upgrades by contacting the Cisco
      Technical Assistance Center (TAC):
      
        * +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
      
      Customers should have the product serial number available and be
      prepared to provide the URL of this advisory as evidence of
      entitlement to a free upgrade. Customers without service contracts
      should request free upgrades through the TAC.
      
      Refer to Cisco Worldwide Contacts at
      http://www.cisco.com/en/US/support/tsd_cisco_worldwide_contacts.html
      for additional TAC contact information, including localized telephone
      numbers, instructions, and e-mail addresses for support in various
      languages.
