Cisco Security Advisory: Cisco IOS Software Session Initiation Protocol Denial of Service Vulnerabilities

Advisory ID: cisco-sa-20100324-sip

Revision 1.0

For Public Release 2010 March 24 1600 UTC (GMT)

+---------------------------------------------------------------------

Summary

Multiple vulnerabilities exist in the Session Initiation Protocol (SIP) implementation in Cisco IOS Software that could allow an unauthenticated, remote attacker to cause a reload of an affected device when SIP operation is enabled. Remote code execution may also be possible.

Cisco has released free software updates that address these vulnerabilities. For devices that must run SIP there are no workarounds; however, mitigations are available to limit exposure of the vulnerabilities.

This advisory is posted at:

http://www.cisco.com/warp/public/707/cisco-sa-20100324-sip.shtml

Note: The March 24, 2010, Cisco IOS Software Security Advisory bundled publication includes seven Security Advisories. Each advisory lists the releases that correct the vulnerability or vulnerabilities detailed in the advisory. The table at the following URL lists releases that correct all Cisco IOS Software vulnerabilities that have been published on March 24, 2010, or earlier:

http://www.cisco.com/warp/public/707/cisco-sa-20100324-bundle.shtml

Individual publication links are in "Cisco Event Response: Semiannual Cisco IOS Software Security Advisory Bundled Publication" at the following link:

http://www.cisco.com/web/about/security/intelligence/Cisco_ERP_mar10.html

Affected Products

These vulnerabilities only affect devices running Cisco IOS Software with SIP voice services enabled.

Vulnerable Products +------------------

Cisco devices running affected Cisco IOS Software versions that are configured to process SIP messages are affected. Creating a dial peer by issuing the command "dial-peer voice" will start the SIP processes, causing the Cisco IOS device to process SIP messages. In addition, several features within Cisco Unified Communications Manager Express, such as ePhones, once configured will also automatically start the SIP process, which will cause the device to start processing SIP messages. An example of an affected configuration follows:

dial-peer voice <Voice dial-peer tag> voip
 ... In the following example, the presence of the

processes "CCSIP_UDP_SOCKET" or "CCSIP_TCP_SOCKET" indicates that the Cisco IOS device will process SIP messages:

Router#show processes | include SIP
 149 Mwe 40F48254            4          1    400023108/24000  0 CCSIP_UDP_SOCKET
 150 Mwe 40F48034            4          1    400023388/24000  0 CCSIP_TCP_SOCKET

Warning: Because there are several ways a device running Cisco IOS Software can start processing SIP messages, it is recommended that the "show processes | include SIP" command be used to determine whether the device is processing SIP messages instead of relying on the presence of specific configuration commands.

Cisco Unified Border Element images are also affected by these vulnerabilities.

Note: The Cisco Unified Border Element feature (previously known as the Cisco Multiservice IP-to-IP Gateway) is a special Cisco IOS Software image that runs on Cisco multiservice gateway platforms. It provides a network-to-network interface point for billing, security, call admission control, quality of service, and signaling interworking.

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)

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)

Products Confirmed Not Vulnerable +--------------------------------

The SIP Application Layer Gateway (ALG), which is used by the Cisco IOS NAT and firewall features of Cisco IOS Software, is not affected by these vulnerabilities.

No other Cisco products are currently known to be affected by these vulnerabilities.

Details

SIP is a popular signaling protocol that is used to manage voice and video calls across IP networks such as the Internet. SIP is responsible for handling all aspects of call setup and termination. Voice and video are the most popular types of sessions that SIP handles, but the protocol has the flexibility to accommodate other applications that require call setup and termination. SIP call signaling can use UDP (port 5060), TCP (port 5060), or TLS (TCP port 5061) as the underlying transport protocol.

In cases where SIP is running over TCP transport, a TCP three-way handshake is necessary to exploit these vulnerabilities.

These vulnerabilities are addressed by Cisco bug IDs CSCsz48680, CSCsz89904, and CSCtb93416, and have been assigned Common Vulnerabilities and Exposures (CVE) IDs CVE-2010-0580, CVE-2010-0581, and CVE-2010-0579, respectively.

Workarounds

If the affected Cisco IOS device requires SIP for VoIP services, SIP cannot be disabled, and no workarounds are available. Users are advised to apply mitigation techniques to help limit exposure to the vulnerabilities. Mitigation consists of allowing only legitimate devices to connect to affected devices. To increase effectiveness, the mitigation must be coupled with anti-spoofing measures on the network edge. This action is required because SIP can use UDP as the transport protocol.

Additional mitigations that can be deployed on Cisco devices within the network are available in the companion document "Cisco Applied Mitigation Bulletin: Identifying and Mitigating Exploitation of the Cisco Unified Communications Manager Express and Cisco IOS Software H.323 and Session Initiation Protocol Denial of Service Vulnerabilities", which is available at the following location:

http://www.cisco.com/warp/public/707/cisco-amb-20100324-voice.shtml

Disable SIP Listening Ports +--------------------------

For devices that do not require SIP to be enabled, the simplest and most effective workaround is to disable SIP processing on the device. Some versions of Cisco IOS Software allow administrators to disable SIP with the following commands:

sip-ua
 no transport udp
 no transport tcp
 no transport tcp tls

Warning: When applying this workaround to devices that are processing Media Gateway Control Protocol (MGCP) or H.323 calls, the device will not stop SIP processing while active calls are being processed. Under these circumstances, this workaround should be implemented during a maintenance window when active calls can be briefly stopped.

The "show udp connections", "show tcp brief all", and "show processes | include SIP" commands can be used to confirm that the SIP UDP and TCP ports are closed after applying this workaround.

Depending on the Cisco IOS Software version in use, the output from the "show ip sockets" command may still show the SIP ports open, but sending traffic to them will cause the SIP process to emit the following message:

*Feb  2 11:36:47.691: sip_udp_sock_process_read: SIP UDP Listener is DISABLED

Control Plane Policing +---------------------

For devices that need to offer SIP services it is possible to use Control Plane Policing (CoPP) to block SIP traffic to the device from untrusted sources. 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 specific network configurations:

!-- The 192.168.1.0/24 network and the 172.16.1.1 host are trusted. 
!-- Everything else is not trusted. The following access list is used
!-- to determine what traffic needs to be dropped by a control plane
!-- policy (the CoPP feature.) If the access list matches (permit)
!-- then traffic will be dropped and if the access list does not
!-- match (deny) then traffic will be processed by the router.

access-list 100 deny udp 192.168.1.0 0.0.0.255 any eq 5060
access-list 100 deny tcp 192.168.1.0 0.0.0.255 any eq 5060
access-list 100 deny tcp 192.168.1.0 0.0.0.255 any eq 5061
access-list 100 deny udp host 172.16.1.1 any eq 5060
access-list 100 deny tcp host 172.16.1.1 any eq 5060
access-list 100 deny tcp host 172.16.1.1 any eq 5061
access-list 100 permit udp any any eq 5060
access-list 100 permit tcp any any eq 5060
access-list 100 permit tcp any any eq 5061

!-- Permit (Police or Drop)/Deny (Allow) all other Layer3 and Layer4
!-- 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-sip-class
  match access-group 100

!-- Create a Policy-Map that will be applied to the
!-- Control-Plane of the device.

policy-map control-plane-policy
 class drop-sip-class
  drop

!-- Apply the Policy-Map to the Control-Plane of the
!-- device.

control-plane
 service-policy input control-plane-policy

Warning: Because SIP can use UDP as a transport protocol, it is possible to easily spoof the IP address of the sender, which may defeat access control lists that permit communication to these ports from trusted IP addresses.

In the above CoPP example, the access control entries (ACEs) 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.

    "data": "Unspecified vulnerability in the SIP implementation in Cisco IOS 12.3 and 12.4 allows remote attackers to execute arbitrary code via a malformed SIP message, aka Bug ID CSCsz89904, the \"SIP Packet Parsing Arbitrary Code Execution Vulnerability.\". The problem is Bug ID : CSCsz89904 It is a problem.A third party may execute arbitrary code. Cisco IOS is prone to a remote code-execution service vulnerability. \nThe attacker can exploit this issue to execute arbitrary code with elevated privileges on affected devices. Successful exploits will completely compromise an affected device. \nThis issue is tracked by Cisco Bug ID CSCsz89904. -----BEGIN PGP SIGNED MESSAGE-----\nHash: SHA1\n\nCisco Security Advisory: Cisco IOS Software Session Initiation\nProtocol Denial of Service Vulnerabilities\n\nAdvisory ID: cisco-sa-20100324-sip\n\nRevision 1.0\n\nFor Public Release 2010 March 24 1600 UTC (GMT)\n\n+---------------------------------------------------------------------\n\nSummary\n=======\n\nMultiple vulnerabilities exist in the Session Initiation Protocol\n(SIP) implementation in Cisco IOS Software that could allow an\nunauthenticated, remote attacker to cause a reload of an affected\ndevice when SIP operation is enabled. Remote code execution may also\nbe possible. \n\nCisco has released free software updates that address these\nvulnerabilities. For devices that must run SIP there are no\nworkarounds; however, mitigations are available to limit exposure of\nthe vulnerabilities. \n\nThis advisory is posted at:\n\nhttp://www.cisco.com/warp/public/707/cisco-sa-20100324-sip.shtml\n\nNote: The March 24, 2010, Cisco IOS Software Security Advisory\nbundled publication includes seven Security Advisories. Each\nadvisory lists the releases that correct the vulnerability or\nvulnerabilities detailed in the advisory. The table at the following\nURL lists releases that correct all Cisco IOS Software\nvulnerabilities that have been published on March 24, 2010, or\nearlier:\n\nhttp://www.cisco.com/warp/public/707/cisco-sa-20100324-bundle.shtml\n\nIndividual publication links are in \"Cisco Event Response: Semiannual\nCisco IOS Software Security Advisory Bundled Publication\" at the\nfollowing link:\n\nhttp://www.cisco.com/web/about/security/intelligence/Cisco_ERP_mar10.html\n\nAffected Products\n=================\n\nThese vulnerabilities only affect devices running Cisco IOS Software\nwith SIP voice services enabled. \n\nVulnerable Products\n+------------------\n\nCisco devices running affected Cisco IOS Software versions that are\nconfigured to process SIP messages are affected. Creating a dial peer by issuing the command \"dial-peer voice\"\nwill start the SIP processes, causing the Cisco IOS device to process\nSIP messages. In addition, several features within Cisco Unified\nCommunications Manager Express, such as ePhones, once configured will\nalso automatically start the SIP process, which will cause the device\nto start processing SIP messages. An example of an affected\nconfiguration follows:\n\n    dial-peer voice \u003cVoice dial-peer tag\u003e voip\n     ... In the following example, the presence of the\nprocesses \"CCSIP_UDP_SOCKET\" or \"CCSIP_TCP_SOCKET\" indicates that the\nCisco IOS device will process SIP messages:\n\n    Router#show processes | include SIP\n     149 Mwe 40F48254            4          1    400023108/24000  0 CCSIP_UDP_SOCKET\n     150 Mwe 40F48034            4          1    400023388/24000  0 CCSIP_TCP_SOCKET\n\nWarning: Because there are several ways a device running\nCisco IOS Software can start processing SIP messages, it is\nrecommended that the \"show processes | include SIP\" command be used to\ndetermine whether the device is processing SIP messages instead of\nrelying on the presence of specific configuration commands. \n\nCisco Unified Border Element images are also affected by these\nvulnerabilities. \n\nNote: The Cisco Unified Border Element feature (previously known as\nthe Cisco Multiservice IP-to-IP Gateway) is a special Cisco IOS\nSoftware image that runs on Cisco multiservice gateway platforms. It\nprovides a network-to-network interface point for billing, security,\ncall admission control, quality of service, and signaling\ninterworking. \n\nTo determine the Cisco IOS Software release that is running on a\nCisco product, administrators can log in to the device and issue the \n\"show version\" command to display the system banner. The system banner\nconfirms that the device is running Cisco IOS Software by displaying\ntext similar to \"Cisco Internetwork Operating System Software\" or\n\"Cisco IOS Software.\" The image name displays in parentheses,\nfollowed by \"Version\" and the Cisco IOS Software release name. Other\nCisco devices do not have the \"show version\" command or may provide\ndifferent output. \n\nThe following example identifies a Cisco product that is running\nCisco IOS Software Release 12.3(26) with an installed image name of\nC2500-IS-L:\n\n    Router#show version\n    Cisco Internetwork Operating System Software\n    IOS (tm) 2500 Software (C2500-IS-L), Version 12.3(26), RELEASE SOFTWARE (fc2)\n    Technical Support: http://www.cisco.com/techsupport\n    Copyright (c) 1986-2008 by cisco Systems, Inc. \n    Compiled Mon 17-Mar-08 14:39 by dchih\n    \n    !--- output truncated\n\nThe following example identifies a Cisco product that is running\nCisco IOS Software Release 12.4(20)T with an installed image name of\nC1841-ADVENTERPRISEK9-M:\n\n    Router#show version\n    Cisco IOS Software, 1841 Software (C1841-ADVENTERPRISEK9-M), Version 12.4(20)T, RELEASE SOFTWARE (fc3)\n    Technical Support: http://www.cisco.com/techsupport\n    Copyright (c) 1986-2008 by Cisco Systems, Inc. \n    Compiled Thu 10-Jul-08 20:25 by prod_rel_team\n    \n    !--- output truncated\n    \nAdditional information about Cisco IOS Software release naming\nconventions is available in \"White Paper: Cisco IOS Reference Guide\"\nat the following link:\n\nhttp://www.cisco.com/warp/public/620/1.html. \n\nProducts Confirmed Not Vulnerable\n+--------------------------------\n\nThe SIP Application Layer Gateway (ALG), which is used by the Cisco\nIOS NAT and firewall features of Cisco IOS Software, is not affected\nby these vulnerabilities. \n\nNo other Cisco products are currently known to be affected by these\nvulnerabilities. \n\nDetails\n=======\n\nSIP is a popular signaling protocol that is used to manage voice and\nvideo calls across IP networks such as the Internet. SIP is\nresponsible for handling all aspects of call setup and termination. \nVoice and video are the most popular types of sessions that SIP\nhandles, but the protocol has the flexibility to accommodate other\napplications that require call setup and termination. SIP call\nsignaling can use UDP (port 5060), TCP (port 5060), or TLS (TCP port\n5061) as the underlying transport protocol. \n\nIn cases where SIP is running over TCP transport, a TCP three-way\nhandshake is necessary to exploit these vulnerabilities. \n\nThese vulnerabilities are addressed by Cisco bug IDs CSCsz48680,\nCSCsz89904, and CSCtb93416, and have been assigned Common\nVulnerabilities and Exposures (CVE) IDs CVE-2010-0580, CVE-2010-0581,\nand CVE-2010-0579, respectively. \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 vulnerabilities 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\nCSCsz89904 and CSCtb93416\n\nCVSS Base Score - 10\n\nAccess Vector           - Network\nAccess Complexity       - Low\nAuthentication          - None\nConfidentiality Impact  - Complete\nIntegrity Impact        - Complete\nAvailability Impact     - Complete\n\nCVSS Temporal Score - 8.3\n\nExploitability          - Functional\nRemediation Level       - Official-Fix\nReport Confidence       - Confirmed\n\nCSCsz48680\n\nCVSS Base Score - 7.8\n\nAccess Vector           - Network\nAccess Complexity       - Low\nAuthentication          - None\nConfidentiality Impact  - None\nIntegrity Impact        - None\nAvailability Impact     - Complete\n\nCVSS Temporal Score - 6.4\n\nExploitability          - Functional\nRemediation Level       - Official-Fix\nReport Confidence       - Confirmed\n\nImpact\n======\n\nSuccessful exploitation of the vulnerabilities in this advisory may\nresult in a reload of the device. Repeated exploitation could result\nin a sustained denial of service 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.

Users are\nadvised to apply mitigation techniques to help limit exposure to the\nvulnerabilities. Mitigation consists of allowing only legitimate\ndevices to connect to affected devices. To increase effectiveness,\nthe mitigation must be coupled with anti-spoofing measures on the\nnetwork edge. This action is required because SIP can use UDP as the\ntransport protocol. \n\nAdditional mitigations that can be deployed on Cisco devices within\nthe network are available in the companion document \"Cisco Applied\nMitigation Bulletin: Identifying and Mitigating Exploitation of the\nCisco Unified Communications Manager Express and Cisco IOS Software\nH.323 and Session Initiation Protocol Denial of Service\nVulnerabilities\", which is available at the following location:\n\nhttp://www.cisco.com/warp/public/707/cisco-amb-20100324-voice.shtml\n\nDisable SIP Listening Ports\n+--------------------------\n\nFor devices that do not require SIP to be enabled, the simplest and\nmost effective workaround is to disable SIP processing on the device. \nSome versions of Cisco IOS Software allow administrators to disable\nSIP with the following commands:\n\n    sip-ua\n     no transport udp\n     no transport tcp\n     no transport tcp tls\n\nWarning: When applying this workaround to devices that are\nprocessing Media Gateway Control Protocol (MGCP) or H.323 calls, the\ndevice will not stop SIP processing while active calls are being\nprocessed. Under these circumstances, this workaround should be\nimplemented during a maintenance window when active calls can be\nbriefly stopped. \n\nThe \"show udp connections\", \"show tcp brief all\", and\n\"show processes | include SIP\" commands can be used to confirm that\nthe SIP UDP and TCP ports are closed after applying this workaround. \n\nDepending on the Cisco IOS Software version in use, the output from\nthe \"show ip sockets\" command may still show the SIP ports open, but\nsending traffic to them will cause the SIP process to emit the\nfollowing message:\n\n    *Feb  2 11:36:47.691: sip_udp_sock_process_read: SIP UDP Listener is DISABLED\n\nControl Plane Policing\n+---------------------\n\nFor devices that need to offer SIP services it is possible to use\nControl Plane Policing (CoPP) to block SIP traffic to the device from\nuntrusted sources. CoPP may be configured on a\ndevice to protect the management and control planes to minimize the\nrisk and effectiveness of direct infrastructure attacks by explicitly\npermitting only authorized traffic sent to infrastructure devices in\naccordance with existing security policies and configurations. The\nfollowing example can be adapted to specific network configurations:\n\n    !-- The 192.168.1.0/24 network and the 172.16.1.1 host are trusted. \n    !-- Everything else is not trusted. The following access list is used\n    !-- to determine what traffic needs to be dropped by a control plane\n    !-- policy (the CoPP feature.) If the access list matches (permit)\n    !-- then traffic will be dropped and if the access list does not\n    !-- match (deny) then traffic will be processed by the router. \n    \n    access-list 100 deny udp 192.168.1.0 0.0.0.255 any eq 5060\n    access-list 100 deny tcp 192.168.1.0 0.0.0.255 any eq 5060\n    access-list 100 deny tcp 192.168.1.0 0.0.0.255 any eq 5061\n    access-list 100 deny udp host 172.16.1.1 any eq 5060\n    access-list 100 deny tcp host 172.16.1.1 any eq 5060\n    access-list 100 deny tcp host 172.16.1.1 any eq 5061\n    access-list 100 permit udp any any eq 5060\n    access-list 100 permit tcp any any eq 5060\n    access-list 100 permit tcp any any eq 5061\n    \n    !-- Permit (Police or Drop)/Deny (Allow) all other Layer3 and Layer4\n    !-- traffic in accordance with existing security policies and\n    !-- configurations for traffic that is authorized to be sent\n    !-- to infrastructure devices. \n    !-- Create a Class-Map for traffic to be policed by\n    !-- the CoPP feature. \n    \n    class-map match-all drop-sip-class\n      match access-group 100\n    \n    !-- Create a Policy-Map that will be applied to the\n    !-- Control-Plane of the device. \n    \n    policy-map control-plane-policy\n     class drop-sip-class\n      drop\n    \n    !-- Apply the Policy-Map to the Control-Plane of the\n    !-- device. \n    \n    control-plane\n     service-policy input control-plane-policy\n\nWarning: Because SIP can use UDP as a transport protocol, it\nis possible to easily spoof the IP address of the sender, which may\ndefeat access control lists that permit communication to these ports\nfrom trusted IP addresses. \n\nIn the above CoPP example, the access control entries (ACEs) that\nmatch the potential exploit packets with the \"permit\" action result\nin these packets being discarded by the policy-map \"drop\" function,\nwhile packets that match the \"deny\" action (not shown) are not\naffected by the policy-map drop function. Additional information on\nthe configuration and use of the CoPP feature can be found at:\n\nhttp://www.cisco.com/web/about/security/intelligence/coppwp_gs.html \n\nhttp://www.cisco.com/en/US/docs/ios/12_3t/12_3t4/feature/guide/gtrtlimt.html\n\nObtaining Fixed Software\n========================\n\nCisco has released free software updates that address these\nvulnerabilities.
