The problem is Bug IDs CSCta20040 and CSCta31358 Problem.Invalid by a third party Refer-To Header is added SIP REFER Denial of service via request (DoS) May be in a state. Cisco Unified Communications Manager is a call processing component in the Cisco IP Telephony solution. When the UDP protocol is used, there is an error in the SIP registration implementation, and special SIP messages can be used to terminate important processes and disrupt voice services. Allow malicious users to conduct denial of service attacks. An attacker can exploit this issue to cause an interruption in voice services or cause the affected device to reload, denying service to legitimate users. This issue is tracked by Cisco Bug IDs CSCta31358 and CSCta20040. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Cisco Security Advisory: Cisco IOS Software Session Initiation Protocol Denial of Service Vulnerabilities Advisory ID: cisco-sa-20100922-sip http://www.cisco.com/warp/public/707/cisco-sa-20100922-sip.shtml Revision 1.0 For Public Release 2010 September 22 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. 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-20100922-sip.shtml Note: The September 22, 2010, Cisco IOS Software Security Advisory bundled publication includes six Cisco 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 September 22, 2010, or earlier: http://www.cisco.com/warp/public/707/cisco-sa-20100922-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_sep10.html Cisco Unified Communications Manager (CUCM) is affected by the vulnerabilities described in this advisory. Two separate Cisco Security Advisories have been published to disclose the vulnerabilities that affect the Cisco Unified Communications Manager at the following locations: http://www.cisco.com/warp/public/707/cisco-sa-20090826-cucm.shtml http://www.cisco.com/warp/public/707/cisco-sa-20100922-cucm.shtml Affected Products ================= These vulnerabilities only affect devices running Cisco IOS Software with SIP voice services enabled. Vulnerable Products +------------------ Cisco devices are affected when they are running affected Cisco IOS Software versions that are configured to process SIP messages. Recent versions of Cisco IOS Software do not process SIP messages by default. In addition, several features within Cisco Unified Communications Manager Express, such as ePhones, will also automatically start the SIP process when they are configured, causing the 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, 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 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. 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) Technical Support: http://www.cisco.com/techsupport Copyright (c) 1986-2008 by cisco Systems, Inc.

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 running Cisco IOS Software processes crafted SIP messages. Note: In cases where SIP is running over TCP transport, a TCP three-way handshake is necessary to exploit these vulnerabilities. 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 CSCta20040 - Device crashes when receiving crafted SIP message 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 CSCsz43987 - IOS coredump when sending crafted packets 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 CSCtf72678 - IOS Coredump Generated when sending crafted packets 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 a reload of the device.

Cisco IOS XR System Software +--------------------------- Cisco IOS XR Software is not affected by the vulnerabilities disclosed in the September 22, 2010, Cisco IOS Software Security Advisory 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 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 Multiple Vulnerabilities in Cisco Voice Products", which is available at the following location: http://www.cisco.com/warp/public/707/cisco-amb-20100922-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 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: *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 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. 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 and http://www.cisco.com/en/US/docs/ios/12_3t/12_3t4/feature/guide/gtrtlimt.html 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.
