VAR-200809-0021
Vulnerability from variot - Updated: 2023-12-18 12:12Memory leak in the Session Initiation Protocol (SIP) implementation in Cisco IOS 12.2 through 12.4, when VoIP is configured, allows remote attackers to cause a denial of service (memory consumption and voice-service outage) via unspecified valid SIP messages. Devices running Cisco IOS with SIP enabled are prone to multiple denial-of-service vulnerabilities. These issues are tracked by the following Cisco bug IDs and CVEs: CSCse56800 (CVE-2008-3799) CSCsg91306 (CVE-2008-3800) CSCsl62609 (CVE-2008-3801) CSCsk42759 (CVE-2008-3802) An attacker can exploit these issues to deny service to legitimate users.
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.
Successful exploitation requires that the device is configured with Network Address Translation (NAT) SCCP Fragmentation Support.
5) Multiple unspecified errors exist in the processing of SIP messages, which can be exploited to cause a reload of an affected device.
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.
NOTE: This security issue was introduced with CSCee83237.
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. This can be exploited to reload an affected device via a specially crafted UDP packet sent to port 1975.
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.

Affected Products
These vulnerabilities only affect devices running Cisco IOS that have SIP voice services enabled. The only requirement for these vulnerabilities is that the Cisco IOS device processes SIP messages as part of configured voice over IP (VoIP) functionality (this does not apply to processing of SIP messages as part of the NAT and firewall feature sets.) Recent versions of Cisco IOS do not process SIP messages by default, but creating a "dial peer" via the command dial-peer voice will start the SIP processes and cause Cisco IOS to start processing SIP messages. An example of an affected configuration is as follows:
dial-peer voice <Voice dial-peer tag> voip
... Please refer to
http://www.cisco.com/warp/public/707/cisco-sa-20070131-sip.shtml for additional information on Cisco bug ID CSCsb25337. In the following example, the presence of the processes CCSIP_UDP_SOCKET and CCSIP_TCP_SOCKET indicates that the Cisco IOS device is processing SIP messages:
Router#show processes | include SIP
147 Mwe 40F46DF4 12 2 600023468/24000 0 CCSIP_SPI_CONTRO
148 Mwe 40F21244 0 1 0 5524/6000 0 CCSIP_DNS
149 Mwe 40F48254 4 1 400023108/24000 0 CCSIP_UDP_SOCKET
150 Mwe 40F48034 4 1 400023388/24000 0 CCSIP_TCP_SOCKET
Different versions of Cisco IOS have different ways of verifying whether the Cisco IOS device is listening for SIP messages. The show ip sockets, show udp, show tcp brief all, and show control-plane host open-ports commands can be used to determine this, although not all of these commands work on all IOS releases. Since it is not practical in this document to provide a list of commands corresponding to the various releases, users should try the aforementioned commands to determine which ones work for their device. The following is one example of one command that shows a router listening on port 5060 (the SIP port):
router#show control-plane host open-ports
Active internet connections (servers and established)
Prot Local Address Foreign Address Service State
<output removed for brevity>
tcp *:5060 *:0 SIP LISTEN
<outoput removed for brevity>
udp *:5060 *:0 SIP LISTEN
In order to determine the software that runs on a Cisco IOS product, log in to the device and issue the show version command to display the system banner. Cisco IOS software identifies itself as "Internetwork Operating System Software" or simply "IOS." On the next line of output, the image name displays between parentheses, followed by "Version" and the Cisco IOS release name. Other Cisco devices do not have the show version command or give different output.
The following example shows output from a device that runs an IOS image:
router>show version
Cisco IOS Software, 7200 Software (C7200-ADVSECURITYK9-M), Version 12.4(6)T2, RELEASE SOFTWARE (fc1)

Additional information on the Cisco IOS release naming conventions can be found on the document entitled "White Paper: Cisco IOS Reference Guide", which is available at http://www.cisco.com/warp/public/620/1.html
Cisco Unified Communications Manager is also affected by some of these vulnerabilities, although they are tracked by different Cisco bug IDs. A companion security advisory for Cisco Unified Communications Manager is available at http://www.cisco.com/warp/public/707/cisco-sa-20080924-cucm.shtml
Products Confirmed Not Vulnerable +--------------------------------
The SIP Application Layer Gateway (ALG), which is used by the IOS Network Address Translation (NAT) and firewall features of Cisco IOS, is not affected by these vulnerabilities.
With the exception of the Cisco Unified Communications Manager, no other Cisco products are currently known to be vulnerable to the issues described in this advisory.
Details
SIP is a popular signaling protocol 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 is flexible to accommodate for 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 all cases vulnerabilities can be triggered by processing valid SIP messages.
Memory Leak Vulnerability +------------------------
CSCse56800 causes a memory leak in affected devices. This vulnerability has been assigned Common Vulnerabilities and Exposures (CVE) ID CVE-2008-3799.
Device Reload Vulnerabilities +----------------------------
The following vulnerabilities can lead to a reload of the Cisco IOS device while processing some specific and valid SIP messages:
- CSCsg91306, assigned CVE ID CVE-2008-3800
- CSCsl62609, assigned CVE ID CVE-2008-3801
- CSCsk42759, assigned CVE ID CVE-2008-3802
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.

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
If the affected Cisco IOS device needs to provide voice over IP services and therefore SIP cannot be disabled then none of the listed vulnerabilities have workarounds. Users are advised to apply mitigation techniques to limit exposure to the listed vulnerabilities. Mitigation consists of only allowing legitimate devices to connect to the routers. 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 Cisco Applied Mitigation Bulletin companion document for this advisory, which is available at the following link: http://www.cisco.com/warp/public/707/cisco-amb-20080924-sip.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 allow administrators to accomplish this with the following commands:
sip-ua
no transport udp
no transport tcp
Warning: When applying this workaround to devices processing MGCP or H.323 calls, the device will not allow you to 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.
It is recommended that after applying this workaround, the show commands discussed in the Vulnerable Products section be used to confirm that the Cisco IOS device is no longer processing SIP messages.
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. Cisco IOS software releases 12.0S, 12.2SX, 12.2S, 12.3T, 12.4, and 12.4T 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:
!-- 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 drop-sip-traffic
class drop-sip-class
drop
!-- Apply the Policy-Map to the Control-Plane of the
!-- device.
control-plane
service-policy input drop-sip-traffic
Warning: Because SIP can utilize UDP as a transport protocol, it is possible to easily spoof the sender's IP address, which may defeat ACLs that permit communication to these ports from trusted IP addresses.
In the above CoPP example, the access control list 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. Additional information on the configuration and use of the CoPP feature can be found at http://www.cisco.com/en/US/products/ps6642/products_white_paper0900aecd804fa16a.shtml and http://www.cisco.com/en/US/products/sw/iosswrel/ps1838/products_feature_guide09186a008052446b.html

Cisco has released free software updates that address these vulnerabilities. Prior to deploying software, customers should consult their maintenance provider or check the software for feature set compatibility and known issues specific to their environment.
Customers may only install and expect support for the feature sets they have purchased. By installing, downloading, accessing or otherwise using such software upgrades, customers agree to be bound by the terms of Cisco's software license terms found at http://www.cisco.com/en/US/products/prod_warranties_item09186a008088e31f.html or as otherwise set forth at Cisco.com Downloads at http://www.cisco.com/public/sw-center/sw-usingswc.shtml
Do not contact psirt@cisco.com or security-alert@cisco.com for software upgrades.
Customers with Service Contracts +-------------------------------
Customers with contracts should obtain upgraded software through their regular update channels. For most customers, this means that upgrades should be obtained through the Software Center on Cisco's worldwide website at http://www.cisco.com
Customers using Third Party Support Organizations +------------------------------------------------
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)
- +1 408 526 7209 (toll call from anywhere in the world)
- e-mail: tac@cisco.com
Customers should have their product serial number available and be prepared to give the URL of this notice as evidence of entitlement to a free upgrade. Free upgrades for non-contract customers must be requested through the TAC.
Refer to http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml for additional TAC contact information, including localized telephone numbers, and instructions and e-mail addresses for use in various languages.

"data": "Memory leak in the Session Initiation Protocol (SIP) implementation in Cisco IOS 12.2 through 12.4, when VoIP is configured, allows remote attackers to cause a denial of service (memory consumption and voice-service outage) via unspecified valid SIP messages. Devices running Cisco IOS with SIP enabled are prone to multiple denial-of-service vulnerabilities. \nThese issues are tracked by the following Cisco bug IDs and CVEs:\nCSCse56800 (CVE-2008-3799)\nCSCsg91306 (CVE-2008-3800)\nCSCsl62609 (CVE-2008-3801)\nCSCsk42759 (CVE-2008-3802)\nAn attacker can exploit these issues to deny service to legitimate users. \n\n1) An unspecified error exists in the processing of SSL packets\nduring the termination of an SSL session, which can potentially be\nexploited to crash an affected system. \n\n2) Two unspecified errors exist within the processing of Protocol\nIndependent Multicast (PIM) packets, which can be exploited to cause\nan affected device to reload. \n\nSuccessful exploitation requires that the device is configured with\nNetwork Address Translation (NAT) SCCP Fragmentation Support. \n\n5) Multiple unspecified errors exist in the processing of SIP\nmessages, which can be exploited to cause a reload of an affected\ndevice. \n\n6) An unspecified error in the IOS Intrusion Prevention System (IPS)\nfeature when processing certain IPS signatures that use the\nSERVICE.DNS engine can be exploited to cause a DoS via specially\ncrafted network traffic. \n\n7) A security issue exists in the processing of extended communities\nwith Multi Protocol Label Switching (MPLS) Virtual Private Networks\n(VPN), which can lead to traffic leaking from one MPLS VPN to\nanother. \n\nNOTE: This security issue was introduced with CSCee83237. \n\n8) An unspecified error within the Multi Protocol Label Switching\n(MPLS) Forwarding Infrastructure (MFI) can be exploited to cause a\nDoS via specially crafted network packets. \n\nSuccessful exploitation requires access to the MPLS network. \n\n9) An unspecified error within the Application Inspection Control\n(AIC) can be exploited to cause a reload of an affected device via\nspecially crafted HTTP packets. \n\n10) An unspecified error in the processing of Layer 2 Tunneling\nProtocol (L2TP) packets can be exploited to cause an affected device\nto reload via a specially crafted L2TP packets. \n\nSuccessful exploitation requires that the L2TP mgmt daemon process is\nrunning. This process may be enabled e.g. via Layer 2 virtual private\nnetworks (L2VPN), Layer 2 Tunnel Protocol Version 3 (L2TPv3), Stack\nGroup Bidding Protocol (SGBP), or Cisco Virtual Private Dial-Up\nNetworks (VPDN). \n\n11) An unspecified error exists in the processing of IPC messages. \nThis can be exploited to reload an affected device via a specially\ncrafted UDP packet sent to port 1975. \n\n12) A security issue is caused due to the device automatically\nenabling SNMP with a default community string, which can be exploited\nto gain control an affected system. \n\nSuccessful exploitation requires that a device is configured for\nlinecard redundancy. \n\nSOLUTION:\nUpdate to the fixed version (please see the vendor\u0027s advisories for\ndetails). \n\nPROVIDED AND/OR DISCOVERED BY:\nReported by the vendor. \n\nORIGINAL ADVISORY:\nCisco:\nhttp://www.cisco.com/warp/public/707/cisco-sa-20080924-ssl.shtml\nhttp://www.cisco.com/warp/public/707/cisco-sa-20080924-multicast.shtml\nhttp://www.cisco.com/warp/public/707/cisco-sa-20080924-sccp.shtml\nhttp://www.cisco.com/warp/public/707/cisco-sa-20080924-sip.shtml\nhttp://www.cisco.com/warp/public/707/cisco-sa-20080924-iosips.shtml\nhttp://www.cisco.com/warp/public/707/cisco-sa-20080924-vpn.shtml\nhttp://www.cisco.com/warp/public/707/cisco-sa-20080924-mfi.shtml\nhttp://www.cisco.com/warp/public/707/cisco-sa-20080924-iosfw.shtml\nhttp://www.cisco.com/warp/public/707/cisco-sa-20080924-l2tp.shtml\nhttp://www.cisco.com/warp/public/707/cisco-sa-20080924-ipc.shtml\nhttp://www.cisco.com/warp/public/707/cisco-sa-20080924-ubr.shtml\n\n----------------------------------------------------------------------\n\nAbout:\nThis Advisory was delivered by Secunia as a free service to help\neverybody keeping their systems up to date against the latest\nvulnerabilities. \n\nSubscribe:\nhttp://secunia.com/advisories/secunia_security_advisories/\n\nDefinitions: (Criticality, Where etc.)\nhttp://secunia.com/advisories/about_secunia_advisories/\n\n\nPlease Note:\nSecunia recommends that you verify all advisories you receive by\nclicking the link. \nSecunia NEVER sends attached files with advisories. \nSecunia does not advise people to install third party patches, only\nuse those supplied by the vendor. \n\n----------------------------------------------------------------------\n\nUnsubscribe: Secunia Security Advisories\nhttp://secunia.com/sec_adv_unsubscribe/?email=packet%40packetstormsecurity.org\n\n----------------------------------------------------------------------\n\n\n. \n\nCisco has released free software updates that address these\nvulnerabilities. Fixed Cisco IOS software listed in the Software\nVersions and Fixes section contains fixes for all vulnerabilities\naddressed in this advisory. \n\nThere are no workarounds available to mitigate the effects of any of\nthe vulnerabilities apart from disabling the protocol or feature\nitself, if administrators do not require the Cisco IOS device to\nprovide voice over IP services. \n\nThis advisory is posted at \nhttp://www.cisco.com/warp/public/707/cisco-sa-20080924-sip.shtml\n\nNote: The September 24, 2008 IOS Advisory bundled publication\nincludes twelve Security Advisories.

Each\nAdvisory lists the releases that correct the vulnerability described\nin the Advisory. Please reference the following software table to\nfind a release that fixes all published IOS software Advisories as of\nSeptember 24th, 2008:\n\nhttp://www.cisco.com/warp/public/707/cisco-sa-20080924-bundle.shtml\n\nIndividual publication links are listed below:\n\n * http://www.cisco.com/warp/public/707/cisco-sa-20080924-iosips.shtml\n * http://www.cisco.com/warp/public/707/cisco-sa-20080924-ssl.shtml\n * http://www.cisco.com/warp/public/707/cisco-sa-20080924-cucm.shtml\n * http://www.cisco.com/warp/public/707/cisco-sa-20080924-vpn.shtml\n * http://www.cisco.com/warp/public/707/cisco-sa-20080924-mfi.shtml\n * http://www.cisco.com/warp/public/707/cisco-sa-20080924-ipc.shtml\n * http://www.cisco.com/warp/public/707/cisco-sa-20080924-ubr.shtml\n * http://www.cisco.com/warp/public/707/cisco-sa-20080924-multicast.shtml\n * http://www.cisco.com/warp/public/707/cisco-sa-20080924-sccp.shtml\n * http://www.cisco.com/warp/public/707/cisco-sa-20080924-iosfw.shtml\n * http://www.cisco.com/warp/public/707/cisco-sa-20080924-l2tp.shtml\n\nAffected Products\n=================\n\nThese vulnerabilities only affect devices running Cisco IOS that have\nSIP voice services enabled. The only requirement for these\nvulnerabilities is that the Cisco IOS device processes SIP messages\nas part of configured voice over IP (VoIP) functionality (this does\nnot apply to processing of SIP messages as part of the NAT and\nfirewall feature sets.) Recent versions of Cisco IOS do not process\nSIP messages by default, but creating a \"dial peer\" via the command\ndial-peer voice will start the SIP processes and cause Cisco IOS to\nstart processing SIP messages. An example of an affected\nconfiguration is as follows:\n\n dial-peer voice \u003cVoice dial-peer tag\u003e voip\n ... Please refer to \nhttp://www.cisco.com/warp/public/707/cisco-sa-20070131-sip.shtml \nfor additional information on Cisco bug ID CSCsb25337. \nIn the following example, the presence of the processes\nCCSIP_UDP_SOCKET and CCSIP_TCP_SOCKET indicates that the Cisco IOS\ndevice is processing SIP messages:\n\n Router#show processes | include SIP\n 147 Mwe 40F46DF4 12 2 600023468/24000 0 CCSIP_SPI_CONTRO\n 148 Mwe 40F21244 0 1 0 5524/6000 0 CCSIP_DNS\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\nDifferent versions of Cisco IOS have different ways of verifying\nwhether the Cisco IOS device is listening for SIP messages. The show\nip sockets, show udp, show tcp brief all, and show control-plane host\nopen-ports commands can be used to determine this, although not all\nof these commands work on all IOS releases. Since it is not practical\nin this document to provide a list of commands corresponding to the\nvarious releases, users should try the aforementioned commands to\ndetermine which ones work for their device. The following is one\nexample of one command that shows a router listening on port 5060\n(the SIP port):\n\n router#show control-plane host open-ports\n Active internet connections (servers and established)\n Prot Local Address Foreign Address Service State\n \u003coutput removed for brevity\u003e\n tcp *:5060 *:0 SIP LISTEN\n \u003coutoput removed for brevity\u003e\n udp *:5060 *:0 SIP LISTEN\n\nIn order to determine the software that runs on a Cisco IOS product,\nlog in to the device and issue the show version command to display\nthe system banner. Cisco IOS software identifies itself as\n\"Internetwork Operating System Software\" or simply \"IOS.\" On the next\nline of output, the image name displays between parentheses, followed\nby \"Version\" and the Cisco IOS release name. Other Cisco devices do\nnot have the show version command or give different output. \n\nThe following example shows output from a device that runs an IOS\nimage:\n\n router\u003eshow version\n Cisco IOS Software, 7200 Software (C7200-ADVSECURITYK9-M), Version 12.4(6)T2, RELEASE SOFTWARE (fc1)\n Technical Support: http://www.cisco.com/techsupport\n Copyright (c) 1986-2006 by Cisco Systems, Inc. \n Compiled Tue 16-May-06 16:09 by kellythw\n \u003cmore output removed for brevity\u003e\n\nAdditional information on the Cisco IOS release naming conventions\ncan be found on the document entitled \"White Paper: Cisco IOS\nReference Guide\", which is available at \nhttp://www.cisco.com/warp/public/620/1.html\n\nCisco Unified Communications Manager is also affected by some of\nthese vulnerabilities, although they are tracked by different Cisco\nbug IDs. A companion security advisory for Cisco Unified\nCommunications Manager is available at \nhttp://www.cisco.com/warp/public/707/cisco-sa-20080924-cucm.shtml\n\nProducts Confirmed Not Vulnerable\n+--------------------------------\n\nThe SIP Application Layer Gateway (ALG), which is used by the IOS\nNetwork Address Translation (NAT) and firewall features of Cisco IOS,\nis not affected by these vulnerabilities. \n\nWith the exception of the Cisco Unified Communications Manager, no\nother Cisco products are currently known to be vulnerable to the\nissues described in this advisory. \n\nDetails\n=======\n\nSIP is a popular signaling protocol used to manage voice and video\ncalls across IP networks such as the Internet. SIP is responsible for\nhandling all aspects of call setup and termination. Voice and video\nare the most popular types of sessions that SIP handles, but the\nprotocol is flexible to accommodate for other applications that\nrequire call setup and termination. SIP call signaling can use UDP\n(port 5060), TCP (port 5060), or TLS (TCP port 5061) as the\nunderlying transport protocol. In all cases vulnerabilities can be\ntriggered by processing valid SIP messages. \n\nMemory Leak Vulnerability\n+------------------------\n\nCSCse56800 causes a memory leak in affected devices. \nThis vulnerability has been assigned Common Vulnerabilities and\nExposures (CVE) ID CVE-2008-3799. \n\nDevice Reload Vulnerabilities\n+----------------------------\n\nThe following vulnerabilities can lead to a reload of the Cisco IOS\ndevice while processing some specific and valid SIP messages:\n\n * CSCsg91306, assigned CVE ID CVE-2008-3800\n * CSCsl62609, assigned CVE ID CVE-2008-3801\n * CSCsk42759, assigned CVE ID CVE-2008-3802\n\nVulnerability Scoring Details\n=============================\n\nCisco has provided scores for the vulnerabilities in this advisory\nbased on the Common Vulnerability Scoring System (CVSS).

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. \n\n+-------------------------------------------------------------------+\n| Major | Availability of Repaired Releases |\n| Release | |\n|------------+------------------------------------------------------|\n| Affected | | Recommended |\n| 12.0-Based | First Fixed Release | Release |\n| Releases | | |\n|-------------------------------------------------------------------|\n| There are no affected 12.0 based releases |\n|-------------------------------------------------------------------|\n| Affected | | Recommended |\n| 12.1-Based | First Fixed Release | Release |\n| Releases | | |\n|-------------------------------------------------------------------|\n| There are no affected 12.1 based releases |\n|-------------------------------------------------------------------|\n| Affected | | Recommended |\n| 12.2-Based | First Fixed Release | Release |\n| Releases | | |\n|------------+---------------------------------------+--------------|\n| 12.2 | Not Vulnerable | |\n|------------+---------------------------------------+--------------|\n| | | 12.4(15)T7 |\n| 12.2B | Vulnerable;

Users are advised to apply\nmitigation techniques to limit exposure to the listed\nvulnerabilities. Mitigation consists of only allowing legitimate\ndevices to connect to the routers. To increase effectiveness, the\nmitigation must be coupled with anti-spoofing measures on the network\nedge. 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 Cisco Applied Mitigation Bulletin\ncompanion document for this advisory, which is available at the\nfollowing link: \nhttp://www.cisco.com/warp/public/707/cisco-amb-20080924-sip.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 allow administrators to accomplish this\nwith the following commands:\n\n sip-ua\n no transport udp\n no transport tcp\n\nWarning: When applying this workaround to devices processing\nMGCP or H.323 calls, the device will not allow you to stop SIP\nprocessing while active calls are being processed. Under these\ncircumstances, this workaround should be implemented during a\nmaintenance window when active calls can be briefly stopped. \n\nIt is recommended that after applying this workaround, the show\ncommands discussed in the Vulnerable Products section be used to\nconfirm that the Cisco IOS device is no longer processing SIP\nmessages. \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. Cisco IOS software releases 12.0S, 12.2SX, 12.2S,\n12.3T, 12.4, and 12.4T support the CoPP feature. CoPP may be\nconfigured on a device to protect the management and control planes\nto minimize the risk and effectiveness of direct infrastructure\nattacks by explicitly permitting only authorized traffic sent to\ninfrastructure devices in accordance with existing security policies\nand configurations. The following example can be adapted to your\nnetwork:\n\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\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\n\n\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\n !-- Create a Policy-Map that will be applied to the\n !-- Control-Plane of the device. \n\n policy-map drop-sip-traffic\n class drop-sip-class\n drop\n\n\n !-- Apply the Policy-Map to the Control-Plane of the\n !-- device. \n\n control-plane\n service-policy input drop-sip-traffic\n\nWarning: Because SIP can utilize UDP as a transport protocol,\nit is possible to easily spoof the sender\u0027s IP address, which may\ndefeat ACLs that permit communication to these ports from trusted\nIP addresses. \n\nIn the above CoPP example, the access control list entries (ACEs)\nthat 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. Additional information\non the configuration and use of the CoPP feature can be found at\nhttp://www.cisco.com/en/US/products/ps6642/products_white_paper0900aecd804fa16a.shtml\nand http://www.cisco.com/en/US/products/sw/iosswrel/ps1838/products_feature_guide09186a008052446b.html\n\nObtaining Fixed Software\n========================\n\nCisco has released free software updates that address these\nvulnerabilities.
