The best practice approach? Fast vulnerability intelligence, threat handling, and setup in one tool. A workaround exists for this SIP vulnerability. Details ======= Cisco Unified Communications Manager is the call processing component of the Cisco IP Telephony solution that extends enterprise telephony features and functions to packet telephony network devices, such as IP phones, media processing devices, VoIP gateways, and multimedia applications. Continued exploitation of the vulnerability may cause a critical process to fail, which could result in the disruption of voice services. Use the following instructions to disable SIP processing: * Step 1: Log in to the Cisco Unified CM Administration web interface. * Step 3: Change the SIP Interoperability Enabled parameter to False and click "Save". Note: For a SIP processing change to take effect, the Cisco CallManager Service must be restarted. For information on how to restart the service, refer to the "Restarting the Cisco CallManager Service" section of the document at http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/admin/7_1_2/ccmcfg/b03dpi.html#wp1075124 It is possible to mitigate this vulnerability by implementing filtering on screening devices and permitting access to TCP ports 5060 and 5061 and UDP ports 5060 and 5061 only from networks that require SIP access to Cisco Unified Communications Manager servers. Affected devices would need to be configured to process SIP messages for these vulnerabilities to be exploitable. Cisco has released free software updates that address these vulnerabilities. There are no workarounds for devices that must run SIP; however, mitigations are available to limit exposure to the vulnerabilities. This advisory is posted at http://www.cisco.com/warp/public/707/cisco-sa-20110928-sip.shtml. Note: The September 28, 2011, Cisco IOS Software Security Advisory bundled publication includes ten Cisco Security Advisories. Each advisory lists the Cisco IOS Software releases that correct the vulnerability or vulnerabilities detailed in the advisory as well as the Cisco IOS Software releases that correct all vulnerabilities in the September 2011 Bundled Publication. 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_sep11.html Cisco Unified Communications Manager (CUCM) is affected by one of the vulnerabilities described in this advisory. Recent versions of Cisco IOS Software do not process SIP messages by default. Creating a dial peer by issuing the "dial-peer voice" configuration command will start the SIP processes, causing the Cisco IOS device to process SIP messages. In addition, several features in Cisco Unified Communications Manager Express, such as ephones, will automatically start the SIP process when they are configured, which could cause the affected device to start processing SIP messages. An example of an affected configuration follows: dial-peer voice <Voice dial-peer tag> voip ... ! In addition to inspecting the Cisco IOS device configuration for a "dial-peer" command that causes the device to process SIP messages, administrators can also use the "show processes | include SIP" command to determine whether Cisco IOS Software is running the processes that handle SIP messages. 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 Note: Because there are several ways a device running Cisco IOS Software can start processing SIP messages, the "show processes | include SIP" command should 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 two of 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. This feature 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 15.0(1)M1 with an installed image name of C3900-UNIVERSALK9-M: Router> show version Cisco IOS Software, C3900 Software (C3900-UNIVERSALK9-M), Version 15.0(1)M1, RELEASE SOFTWARE (fc1) Technical Support: http://www.cisco.com/techsupport Copyright (c) 1986-2009 by Cisco Systems, Inc. Compiled Wed 02-Dec-09 17:17 by prod_rel_team !--- output truncated Additional information about Cisco IOS Software release naming conventions is available in the white paper Cisco IOS and NX-OS Software Reference Guide available at http://www.cisco.com/web/about/security/intelligence/ios-ref.html. Cisco IOS XE Software is affected by these vulnerabilities. Cisco IOS XR 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 Transport Layer Security (TLS; TCP port 5061) as the underlying transport protocol. These vulnerabilities are triggered when the device that is running Cisco IOS Software processes crafted SIP messages. Only traffic destined to the device can trigger the vulnerabilities; transit SIP traffic is not an exploit vector. Note: In cases where SIP is running over TCP transport, a TCP three-way handshake is necessary to exploit these vulnerabilities. This vulnerability has been assigned Common Vulnerabilities and Exposures (CVE) ID CVE-2011-0939. CSCti48504 may cause memory leaks. This vulnerability has been assigned CVE ID CVE-2011-3275. CSCto88686 may cause memory leaks or reloads of affected devices. This vulnerability has been assigned CVE ID CVE-2011-2072. 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 Cisco has also provided a CVSS calculator to help compute the environmental impact for individual networks at http://intellishield.cisco.com/security/alertmanager/cvss Note that all vulnerabilities in this advisory (CSCth03022, CSCti48504, and CSCto88686) have been scored in an identical manner, assuming a complete denial of service (DoS) condition. * CSCth03022, CSCti48504, CSCto88686 CVSS Base Score - 7.8 Access Vector - Network Access Complexity - Low Authentication - None Confidentiality Impact - None Integrity Impact - None Availability Impact - Complete CVSS Temporal Score - 6.4 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed Impact ====== Successful exploitation of the vulnerabilities in this advisory may result in system instabilities or a reload of an affected device. Repeated exploitation could result in a sustained 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.

Cisco IOS XR System Software +--------------------------- Cisco IOS XR Software is not affected by any of the vulnerabilities in the September 2011 bundled publication. 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 measures against spoofing 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 Multiple Vulnerabilities in Cisco Voice Products" at the following location: http://www.cisco.com/warp/public/707/cisco-amb-20110928-voice.shtml. Disabling 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, when SIP is disabled, 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 display the following message: *Jun 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. Cisco IOS 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 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 Note: Because SIP can use UDP as a transport protocol, it is possible to spoof the source address of an IP packet, which may bypass access control lists that permit communication to these ports from trusted IP addresses. In the preceding CoPP example, the access control entries (ACEs) that match the potential exploit packets with the permit action cause these packets to be discarded by the policy-map drop function, whereas packets that match the deny action (not shown) are not affected by the policy-map drop function.

Obtaining Fixed Software ======================== 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/docs/general/warranty/English/EU1KEN_.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.

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).
