TITLE: Cisco IOS Multiple Vulnerabilities
SECUNIA ADVISORY ID: SA31990
VERIFY ADVISORY: http://secunia.com/advisories/31990/
CRITICAL: Moderately critical
IMPACT: Exposure of sensitive information, DoS, System access
WHERE:
From remote
OPERATING SYSTEM: Cisco IOS R12.x http://secunia.com/advisories/product/50/ Cisco IOS 12.x http://secunia.com/advisories/product/182/
DESCRIPTION: Some vulnerabilities have been reported in Cisco IOS, which can be exploited by malicious people to disclose sensitive information, cause a DoS (Denial of Service), or to compromise a vulnerable system.
1) An unspecified error exists in the processing of SSL packets during the termination of an SSL session, which can potentially be exploited to crash an affected system.
2) Two unspecified errors exist within the processing of Protocol Independent Multicast (PIM) packets, which can be exploited to cause an affected device to reload.
3) Unspecified errors within the processing of segmented Skinny Call Control Protocol (SCCP) messages can be exploited to cause a Cisco IOS device to reload.
Successful exploitation requires that the device is configured with Network Address Translation (NAT) SCCP Fragmentation Support.
4) A memory leak in the processing of Session Initiation Protocol (SIP) messages can be exploited to cause a DoS for all voice services.
6) An unspecified error in the IOS Intrusion Prevention System (IPS) feature when processing certain IPS signatures that use the SERVICE.DNS engine can be exploited to cause a DoS via specially crafted network traffic.
7) A security issue exists in the processing of extended communities with Multi Protocol Label Switching (MPLS) Virtual Private Networks (VPN), which can lead to traffic leaking from one MPLS VPN to another.
8) An unspecified error within the Multi Protocol Label Switching (MPLS) Forwarding Infrastructure (MFI) can be exploited to cause a DoS via specially crafted network packets.
Successful exploitation requires access to the MPLS network.
9) An unspecified error within the Application Inspection Control (AIC) can be exploited to cause a reload of an affected device via specially crafted HTTP packets.
10) An unspecified error in the processing of Layer 2 Tunneling Protocol (L2TP) packets can be exploited to cause an affected device to reload via a specially crafted L2TP packets.
Successful exploitation requires that the L2TP mgmt daemon process is running. This process may be enabled e.g. via Layer 2 virtual private networks (L2VPN), Layer 2 Tunnel Protocol Version 3 (L2TPv3), Stack Group Bidding Protocol (SGBP), or Cisco Virtual Private Dial-Up Networks (VPDN).
11) An unspecified error exists in the processing of IPC messages.
12) A security issue is caused due to the device automatically enabling SNMP with a default community string, which can be exploited to gain control an affected system.
Successful exploitation requires that a device is configured for linecard redundancy.
SOLUTION: Update to the fixed version (please see the vendor's advisories for details).
PROVIDED AND/OR DISCOVERED BY: Reported by the vendor.

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
!
Additional information on the configuration and use of the CoPP feature can be found at http://www.cisco.com/web/about/security/intelligence/coppwp_gs.html, http://www.cisco.com/en/US/prod/collateral/iosswrel/ps6537/ps6586/ps6642/prod_white_paper0900aecd804fa16a.html and http://www.cisco.com/en/US/docs/ios/12_3t/12_3t4/feature/guide/gtrtlimt.html
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.
!
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.
!

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.

The following example shows an output taken\nfrom a Cisco 10000 series device running Cisco IOS software release\n12.2(31)SB10e:\n\n c10k#show version | include IOS\n Cisco IOS Software, 10000 Software (C10K3-P11-M), Version 12.2(31)SB10e, RELEASE SOFTWARE (fc1)\n c10k#\n\nThe following example shows an output taken from a Cisco uBR10012\nseries device running Cisco IOS software release 12.3(17b)BC7:\n\n ubr10k#show version | include IOS\n IOS (tm) 10000 Software (UBR10K-K8P6U2-M), Version 12.3(17b)BC7, RELEASE SOFTWARE (fc1)\n ubr10k#\n\nThe following example shows an output taken from a Cisco uBR7200\nseries device running Cisco IOS software release 12.3(21a)BC2:\n\n ubr7200#show version | include IOS\n IOS (tm) 7200 Software (UBR7200-IK9SU2-M), Version 12.3(21a)BC2, RELEASE SOFTWARE (fc1)\n ubr7200#\n\nPlease refer to the document entitled \"White Paper: Cisco IOS\nReference Guide\" for additional information on the Cisco IOS release\nnaming conventions. This document is available at the following link:\nhttp://www.cisco.com/warp/public/620/1.html\n\nAny version of Cisco IOS prior to the fixed versions listed in the\nSoftware Versions and Fixes section below is vulnerable. \n\nNo other Cisco products are currently known to be affected by this\nvulnerability. This channel uses addresses from the 127.0.0.0/8 range and\nUDP port 1975. \n\nFiltering unauthorized traffic destined to 127.0.0.0/8 or UDP port\n1975 will mitigate this vulnerability. \n\nThis vulnerability is documented in the Cisco Bug IDs CSCsg15342 \nand CSCsh29217 and has been assigned Common Vulnerabilities and \nExposures (CVE) ID CVE-2008-3805. \n\nVulnerability Scoring Details\n=============================\n\nCisco has provided scores for the vulnerabilities in this advisory\nbased on the Common Vulnerability Scoring System (CVSS). The CVSS\nscoring in this Security Advisory is done in accordance with CVSS\nversion 2.0. \n\nCVSS is a standards-based scoring method that conveys vulnerability\nseverity and helps determine urgency and priority of response. \n\nCisco has provided a base and temporal score. Customers can then\ncompute environmental scores to assist in determining the impact of\nthe vulnerability in individual networks. \n\nCisco has provided an FAQ to answer additional questions regarding\nCVSS at\n\nhttp://www.cisco.com/web/about/security/intelligence/cvss-qandas.html\n\nCisco has also provided a CVSS calculator to help compute the\nenvironmental impact for individual networks at\n\nhttp://intellishield.cisco.com/security/alertmanager/cvss\n\nCSCsg15342 - IPC processing needs to be more robust\n\nCVSS Base Score - 8.5\n\n Access Vector - Network\n Access Complexity - Low\n Authentication - None\n Confidentiality Impact - None\n Integrity Impact - Partial\n Availability Impact - Complete\n\nCVSS Temporal Score - 7\n\n Exploitability - Functional\n Remediation Level - Official-Fix\n Report Confidence - Confirmed\n\n\nCSCsh29217 - IPC processing needs to be more robust\n\nCVSS Base Score - 8.5\n\n Access Vector - Network\n Access Complexity - Low\n Authentication - None\n Confidentiality Impact - None\n Integrity Impact - Partial\n Availability Impact - Complete\n\nCVSS Temporal Score - 7\n\n Exploitability - Functional\n Remediation Level - Official-Fix\n Report Confidence - Confirmed\n\nImpact\n======\n\nSuccessful exploitation of the vulnerability may result in a reload\nof the device, linecards, or both, resulting in a DoS condition. \n\nSoftware Versions and Fixes\n===========================\n\nWhen considering software upgrades, also consult \nhttp://www.cisco.com/go/psirt and any subsequent advisories to \ndetermine exposure and a complete upgrade solution. \n\nIn all cases, customers should exercise caution to be certain the\ndevices to be upgraded contain sufficient memory and that current\nhardware and software configurations will continue to be supported\nproperly by the new release. If the information is not clear, contact\nthe Cisco Technical Assistance Center (TAC) or your contracted\nmaintenance provider for assistance. \n\nEach row of the Cisco IOS software table (below) names a Cisco IOS\nrelease train. If a given release train is vulnerable, then the\nearliest possible releases that contain the fix (along with the\nanticipated date of availability for each, if applicable) are listed\nin the \"First Fixed Release\" column of the table. The \"Recommended\nRelease\" column indicates the releases which have fixes for all the\npublished vulnerabilities at the time of this Advisory. A device\nrunning a release in the given train that is earlier than the release\nin a specific column (less than the First Fixed Release) is known to\nbe vulnerable. Cisco recommends upgrading to a release equal to or\nlater than the release in the \"Recommended Releases\" column of the\ntable.

that are sent to port 1975. \n\nUsing Interface Access Control Lists\n+-----------------------------------\n\nAccess lists that filter UDP packets destined to port 1975 can be\nused to mitigate this vulnerability. UDP port 1975 is a registered\nport number that can be used by certain applications. However,\nfiltering all packets that are destined to UDP port 1975 may cause\nsome applications to malfunction. Therefore, access lists need to\nexplicitly deny UDP 1975 packets that are sent to any router\ninterface IP addresses and permit transit traffic. Such access lists\nneed to be applied on all interfaces to be effective. Since the IPC\nchannel uses addresses from the 127.0.0.0/8 range, it is also\nnecessary to filter packets that are sourced from or destined to this\nrange. An example is given below:\n\n access-list 100 deny udp any host \u003crouter-interface 1\u003e eq 1975\n access-list 100 deny udp any host \u003crouter-interface 2\u003e eq 1975\n access-list 100 deny udp any host \u003crouter-interface ...\u003e eq 1975\n access-list 100 deny ip 127.0.0.0 0.255.255.255 any\n access-list 100 deny ip any 127.0.0.0 0.255.255.255\n access-list 100 permit ip any any\n\n interface Serial 0/0\n ip access-group 100 in\n\nUsing Control Plane Policing\n+---------------------------\n\nControl Plane Policing (CoPP) can be used to block untrusted UDP port\n1975 access to the affected device. Cisco IOS software releases\n12.2BC and 12.2SCA support the CoPP feature. CoPP may be configured\non a device to protect the management and control planes to minimize\nthe risk and effectiveness of direct infrastructure attacks by\nexplicitly permitting only authorized traffic sent to infrastructure\ndevices in accordance with existing security policies and\nconfigurations. The following example can be adapted to your network. \n\nNote: CoPP is not supported on uBR10012 series devices. \n\n\n !-- Permit all UDP/1975 traffic so that it\n !-- will be policed and dropped by the CoPP feature\n\n !\n access-list 111 permit udp any any eq 1975\n access-list 111 permit ip any 127.0.0.0 0.255.255.255\n access-list 111 permit ip 127.0.0.0 0.255.255.255 any\n !\n\n !-- Permit (Police or Drop)/Deny (Allow) all other Layer 3 and\n !-- Layer 4 traffic in accordance with existing security policies\n !-- and configurations for traffic that is authorized to be sent\n !-- to infrastructure devices\n\n !\n\n !-- Create a Class-Map for traffic to be policed by the CoPP\n !-- feature\n\n !\n class-map match-all drop-IPC-class\n match access-group 111\n !\n\n !-- Create a Policy-Map that will be applied to the Control-Plane\n !-- of the device\n\n !\n policy-map drop-IPC-traffic\n class drop-IPC-class\n drop\n !\n\n !-- Apply the Policy-Map to the Control-Plane of the device\n\n !\n control-plane\n service-policy input drop-IPC-traffic\n !\n\nIn the above CoPP example, the access control list entries (ACEs)\nwhich match the potential exploit packets with the \"permit\" action\nresult in these packets being discarded by the policy-map \"drop\"\nfunction, while packets that match the \"deny\" action (not shown) are\nnot affected by the policy-map drop function. \n\nPlease note that in the Cisco IOS 12.2S and 12.0S trains the\npolicy-map syntax is different:\n\n !\n policy-map drop-IPC-traffic class drop-IPC-class\n police 32000 1500 1500 conform-action drop exceed-action drop\n !\n\nAdditional information on the configuration and use of the CoPP\nfeature can be found at \nhttp://www.cisco.com/web/about/security/intelligence/coppwp_gs.html,\nhttp://www.cisco.com/en/US/prod/collateral/iosswrel/ps6537/ps6586/ps6642/prod_white_paper0900aecd804fa16a.html\nand http://www.cisco.com/en/US/docs/ios/12_3t/12_3t4/feature/guide/gtrtlimt.html\n\nUsing Infrastructure ACLs at Network Boundary\n+--------------------------------------------\n\nAlthough it is often difficult to block traffic transiting your\nnetwork, it is possible to identify traffic which should never be\nallowed to target your infrastructure devices and block that traffic\nat the border of your network. iACLs are a network security best\npractice and should be considered as a long-term addition to good\nnetwork security as well as a workaround for this specific\nvulnerability. The iACL example shown below should be included as\npart of the deployed infrastructure access-list which will protect\nall devices with IP addresses in the infrastructure IP address range:\n\n\n !-- Note: IPC packets sent to UDP destination port 1975 must not\n !-- be permitted from any trusted source as this traffic\n !-- should only be sent and received internally by the\n !-- affected device using an IP address allocated from the\n !-- 127.0.0.0/8 prefix. \n !--\n !-- IPC that traffic that is internally generated and sent\n !-- and/or received by the affected device is not subjected\n !-- to packet filtering by the applied iACL policy. \n\n !\n access-list 150 deny udp any host INTERFACE_ADDRESS#1 eq 1975\n access-list 150 deny udp any host INTERFACE_ADDRESS#2 eq 1975\n access-list 150 deny udp any host INTERFACE_ADDRESS#N eq 1975\n !\n\n !-- Deny all IP packets with a source or destination IP address \n !-- from the 127.0.0.0/8 prefix. \n\n !\n access-list 150 deny ip 127.0.0.0 0.255.255.255 any\n access-list 150 deny ip any 127.0.0.0 0.255.255.255\n !\n\n\n !-- Permit/deny all other Layer 3 and Layer 4 traffic in accordance\n !-- with existing security policies and configurations. \n\n !\n\n !-- Permit all other traffic to transit the device. \n\n !\n access-list 150 permit ip any any\n !\n\n !-- Apply iACL to interfaces in the ingress direction. \n\n !\n interface GigabitEthernet0/0\n ip access-group 150 in\n !\n\nNote: iACLs that filter UDP packets destined to port 1975 can be used\nto mitigate this vulnerability. However, UDP port 1975 is a\nregistered port number that can be used by certain applications. \nFiltering all packets that are destined to UDP port 1975 may cause\nsome applications to malfunction. Therefore, the iACL policy needs to\nexplicitly deny UDP packets using a destination port of 1975 that are\nsent to any router interface IP addresses for affected devices, then\npermit and/or deny all other Layer 3 and Layer 4 traffic in\naccordance with existing security policies and configurations, and\nthen permit all other traffic to transit the device. iACLs must be\napplied on all interfaces to be used effectively. Since the IPC\nchannel uses addresses from the 127.0.0.0/8 range, it is also\nnecessary to filter packets that are sourced from or destined to this\nrange as provided in the preceding example. \n\nThe white paper entitled \"Protecting Your Core: Infrastructure\nProtection Access Control Lists\" presents guidelines and recommended\ndeployment techniques for infrastructure protection access lists. \nThis white paper can be obtained here:\n\nhttp://www.cisco.com/en/US/tech/tk648/tk361/technologies_white_paper09186a00801a1a55.shtml\n\nAdditional Mitigation Techniques\n+-------------------------------\n\nAdditional mitigation techniques that can be deployed on Cisco\ndevices within the network are available in the Cisco Applied\nMitigation Bulletin companion document for this advisory, which is\navailable at the following link:\n\nhttp://www.cisco.com/warp/public/707/cisco-amb-20080924-ipc-and-ubr.shtml\n\nObtaining Fixed Software\n========================\n\nCisco has released free software updates that address these\nvulnerabilities.
