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. Five of
the advisories address vulnerabilities in Cisco IOS Software, and one
advisory addresses vulnerabilities in Cisco Unified Communications
Manager. 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

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. Creating a dial peer by issuing the dial-peer voice command
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, 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)

Note: 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
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.
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.
Three vulnerabilities exist in the SIP implementation in Cisco IOS
Software that may allow a remote attacker to cause an affected device
to reload. 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.
These vulnerabilities are addressed by Cisco bug IDs CSCta20040,
CSCsz43987 and CSCtf72678, and have been assigned Common
Vulnerabilities and Exposures (CVE) IDs CVE-2010-2835, CVE-2009-2051
and CVE-2010-2834, respectively.
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.
