      Summary
      =======
      
      Cisco 10000, uBR10012 and uBR7200 series devices use a User Datagram
      Protocol (UDP) based Inter-Process Communication (IPC) channel that
      is externally reachable. An attacker could exploit this vulnerability
      to cause a denial of service (DoS) condition on affected devices. No
      other platforms are affected.
      
      Cisco has released free software updates that address this
      vulnerability. Workarounds that mitigate this vulnerability are
      available.

      Affected Products
      =================
      
      Cisco 10000, uBR10012 and uBR7200 series devices that are running an
      affected version of Cisco IOS are affected.
      
      Vulnerable Products
      +------------------
      
      Devices that are running Cisco IOS can be identified by using the
      show version command. The following example shows an output taken
      from a Cisco 10000 series device running Cisco IOS software release
      12.2(31)SB10e:
      
          c10k#show version | include IOS
          Cisco IOS Software, 10000 Software (C10K3-P11-M), Version 12.2(31)SB10e, RELEASE SOFTWARE (fc1)
          c10k#
      
      The following example shows an output taken from a Cisco uBR10012
      series device running Cisco IOS software release 12.3(17b)BC7:
      
          ubr10k#show version | include IOS
          IOS (tm) 10000 Software (UBR10K-K8P6U2-M), Version 12.3(17b)BC7, RELEASE SOFTWARE (fc1)
          ubr10k#
      
      The following example shows an output taken from a Cisco uBR7200
      series device running Cisco IOS software release 12.3(21a)BC2:
      
          ubr7200#show version | include IOS
          IOS (tm) 7200 Software (UBR7200-IK9SU2-M), Version 12.3(21a)BC2, RELEASE SOFTWARE (fc1)
          ubr7200#
      
      Please refer to the document entitled "White Paper: Cisco IOS
      Reference Guide" for additional information on the Cisco IOS release
      naming conventions. This document is available at the following link:
      http://www.cisco.com/warp/public/620/1.html
      
      Any version of Cisco IOS prior to the fixed versions listed in the
      Software Versions and Fixes section below is vulnerable.
      
      Products Confirmed Not Vulnerable
      +--------------------------------
      
      Cisco uBR7100 series devices are not affected.
      
      No other Cisco products are currently known to be affected by this
      vulnerability.
      
      Details
      =======
      
      Cisco 10000, uBR10012 and uBR7200 series devices use a UDP-based IPC
      channel. This channel uses addresses from the 127.0.0.0/8 range and
      UDP port 1975. Cisco 10000, uBR10012 and uBR7200 series devices that
      are running an affected version of Cisco IOS will process IPC
      messages that are sent to UDP port 1975 from outside of the device.
      This behavior may be exploited by an attacker to cause a reload of
      the device, linecards, or both, resulting in a DoS condition.
      
      Filtering unauthorized traffic destined to 127.0.0.0/8 or UDP port
      1975 will mitigate this vulnerability.
      
      This vulnerability is documented in the Cisco Bug IDs CSCsg15342 
      and CSCsh29217 and has been assigned Common Vulnerabilities and 
      Exposures (CVE) ID CVE-2008-3805.
      
      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

      of the device, linecards, or both, resulting in a 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
      ===========
      
      Workarounds consist of filtering packets that are sent to 127.0.0.0/8
      range and UDP packets that are sent to port 1975.
      
      Using Interface Access Control Lists
      +-----------------------------------
      
      Access lists that filter UDP packets destined to port 1975 can be
      used to mitigate this vulnerability. UDP port 1975 is a registered
      port number that can be used by certain applications. However,
      filtering all packets that are destined to UDP port 1975 may cause
      some applications to malfunction. Therefore, access lists need to
      explicitly deny UDP 1975 packets that are sent to any router
      interface IP addresses and permit transit traffic. Such access lists
      need to be applied on all interfaces to be effective. Since the IPC
      channel uses addresses from the 127.0.0.0/8 range, it is also
      necessary to filter packets that are sourced from or destined to this
      range. An example is given below:
      
          access-list 100 deny udp any host <router-interface 1> eq 1975
          access-list 100 deny udp any host <router-interface 2> eq 1975
          access-list 100 deny udp any host <router-interface ...> eq 1975
          access-list 100 deny ip 127.0.0.0 0.255.255.255 any
          access-list 100 deny ip any 127.0.0.0 0.255.255.255
          access-list 100 permit ip any any
      
          interface Serial 0/0
            ip access-group 100 in
      
      Using Control Plane Policing
      +---------------------------
      
      Control Plane Policing (CoPP) can be used to block untrusted UDP port
      1975 access to the affected device. Cisco IOS software releases
      12.2BC and 12.2SCA 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 by
      explicitly permitting only authorized traffic sent to infrastructure
      devices in accordance with existing security policies and
      configurations. The following example can be adapted to your network.
      
      Note: CoPP is not supported on uBR10012 series devices.
      
      
          !-- Permit all UDP/1975 traffic so that it
          !-- will be policed and dropped by the CoPP feature
      
          !
          access-list 111 permit udp any any eq 1975
          access-list 111 permit ip any 127.0.0.0 0.255.255.255
          access-list 111 permit ip 127.0.0.0 0.255.255.255 any
          !
      
          !-- 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-IPC-class
            match access-group 111
          !
      
          !-- Create a Policy-Map that will be applied to the Control-Plane
          !-- of the device
      
          !
          policy-map drop-IPC-traffic
            class drop-IPC-class
              drop
          !
      
          !-- Apply the Policy-Map to the Control-Plane of the device
      
          !
          control-plane
            service-policy input drop-IPC-traffic
          !
      
      In the above CoPP example, the access control list entries (ACEs)
      which 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 in the Cisco IOS 12.2S and 12.0S trains the
      policy-map syntax is different:
      
          !
          policy-map drop-IPC-traffic class drop-IPC-class
            police 32000 1500 1500 conform-action drop exceed-action drop
          !

      feature can be found at

      Using Infrastructure ACLs at Network Boundary
      +--------------------------------------------
      
      Although it is often difficult to block traffic transiting your
      network, it is possible to identify traffic which should never be
      allowed to target your infrastructure devices and block that traffic
      at the border of your network. 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 this specific
      vulnerability. The iACL example shown 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:
      
      
          !-- Note: IPC packets sent to UDP destination port 1975 must not
          !--       be permitted from any trusted source as this traffic
          !--       should only be sent and received internally by the
          !--       affected device using an IP address allocated from the
          !--       127.0.0.0/8 prefix.
          !--
          !--       IPC that traffic that is internally generated and sent
          !--       and/or received by the affected device is not subjected
          !--       to packet filtering by the applied iACL policy.
      
          !
      
          !-- Deny IPC (UDP port 1975) packets from all sources destined to
          !-- all IP addresses configured on the affected device.
      
          !
          access-list 150 deny udp any host INTERFACE_ADDRESS#1 eq 1975
          access-list 150 deny udp any host INTERFACE_ADDRESS#2 eq 1975
          access-list 150 deny udp any host INTERFACE_ADDRESS#N eq 1975
          !
      
          !-- Deny all IP packets with a source or destination IP address 
          !-- from the 127.0.0.0/8 prefix.
      
          !
          access-list 150 deny ip 127.0.0.0 0.255.255.255 any
          access-list 150 deny ip any 127.0.0.0 0.255.255.255
          !
      
      
          !-- Permit/deny all other Layer 3 and Layer 4 traffic in accordance
          !-- with existing security policies and configurations.
      
          !
      
          !-- Permit all other traffic to transit the device.
      
          !
          access-list 150 permit ip any any
          !
      
          !-- Apply iACL to interfaces in the ingress direction.
      
          !
          interface GigabitEthernet0/0
            ip access-group 150 in
          !
      
      Note: iACLs that filter UDP packets destined to port 1975 can be used
      to mitigate this vulnerability. However, UDP port 1975 is a
      registered port number that can be used by certain applications.
      Filtering all packets that are destined to UDP port 1975 may cause
      some applications to malfunction. Therefore, the iACL policy needs to
      explicitly deny UDP packets using a destination port of 1975 that are
      sent to any router interface IP addresses for affected devices, then
      permit and/or deny all other Layer 3 and Layer 4 traffic in
      accordance with existing security policies and configurations, and
      then permit all other traffic to transit the device. iACLs must be
      applied on all interfaces to be used effectively. Since the IPC
      channel uses addresses from the 127.0.0.0/8 range, it is also
      necessary to filter packets that are sourced from or destined to this
      range as provided in the preceding example.

      Protection Access Control Lists" presents guidelines and recommended
