Voice Vulnerabilities in Cisco IOS and Cisco Unified Communications Manager
Advisory ID: cisco-sa-20070808-IOS-voice
http://www.cisco.com/warp/public/707/cisco-sa-20070808-IOS-voice.shtml
Revision 1.0
For Public Release 2007 August 08 1600 UTC (GMT)
- -----------------------------------------------------------------------
Summary
=======
Multiple voice-related vulnerabilities are identified in Cisco IOS
software, one of which is also shared with Cisco Unified Communications
Manager. These vulnerabilities pertain to the following protocols or
features:
* Session Initiation Protocol (SIP)
* Media Gateway Control Protocol (MGCP)
* Signaling protocols H.323, H.254
* Real-time Transport Protocol (RTP)
* Facsimile reception
Cisco has made free software available to address these vulnerabilities
for affected customers. Fixed Cisco IOS software listed in the Software
Versions and Fixes section contains fixes for all vulnerabilities
mentioned in this advisory.
There are no workarounds available to mitigate the effects of any of
the vulnerabilities apart from disabling the protocol or feature
itself.
This advisory is posted at
http://www.cisco.com/warp/public/707/cisco-sa-20070808-IOS-voice.shtml.
Note: The August 08, 2007 publication includes four Security Advisories
and one Security Response. The advisories all affect IOS, one
additionally affects Cisco Unified Communications Manager as well. Each
advisory lists the releases that correct the vulnerability described in
the advisory, and the advisories also detail the releases that correct
the vulnerabilities in all four advisories. Individual publication

Affected Products
=================
These vulnerabilities only affect devices running Cisco IOS that have
voice services enabled. The only exception is the vulnerability
documented as Cisco bug ID CSCsi80102, which also exists on Cisco
Unified Communications Manager.
Vulnerable Products
+------------------
To determine the software running on a Cisco IOS product, log in to the
device and issue the "show version" command to display the system banner.
Cisco IOS software will identify itself as "Internetwork Operating
System Software" or simply "IOS." On the next line of output, the image
name will be displayed between parentheses, followed by "Version" and
the Cisco IOS release name. Other Cisco devices will not have the
"show version" command, or will give different output.
The following example shows output from a device running an IOS image:
Router>show version
Cisco IOS Software, 7200 Software (C7200-IK9S-M), Version 12.3(14)T1, RELEASE SOFTWARE (fc1)

SIP-related vulnerabilities
+--------------------------
Any Cisco device that runs a vulnerable version of IOS and supports SIP
processing could be vulnerable. This includes IOS versions 12.3(4)XH,
12.3(4)XQ, 12.3(7)XR, 12.3(7)XS, 12.3(8)JA, 12.3(8)T, 12.3(8)XU, 12.3
(8)XW, 12.3(8)XX, 12.3(8)XY, 12.3(8)YA, 12.3(8)YG, 12.3(8)YH, 12.3(8)
YI, 12.3(8)ZA, 12.4 Mainline and 12.4T onward. Routers that are
configured as SIP Public Switched Telephone Network (PSTN) Gateways and
SIP Session Border Controllers (SBCs) are vulnerable. The CAT6000-CMM
card is also vulnerable.
To determine if the device has SIP enabled, enter the commands
"show ip sockets" and "show tcp brief all". In some newer IOS releases
the command "show ip sockets" is removed. If that is the case use "show udp".
The output is identical to the "show ip sockets" command.
Router#show ip sockets
Proto Remote Port Local Port In Out Stat TTY OutputIF
17 0.0.0.0 0 --any-- 5060 0 0 211 0
17 0.0.0.0 0 192.168.100.2 67 0 0 2211 0
17 0.0.0.0 0 192.168.100.2 2517 0 0 11 0
The first line with UDP Port 5060 shows that UDP SIP is enabled.
Router#show tcp brief all
TCB Local Address Foreign Address (state)
2051E680 *.5060 *.* LISTEN
The above lines with *.5060 show that TCP SIP is enabled.
The device is vulnerable even if it does not have SIP explicitly
configured. If the output of the "show ip sockets" command is showing
that the device is listening to port 5060, then the device is
vulnerable.
MGCP-related vulnerabilities
+---------------------------
To determine whether MGCP is configured on an IOS device, look for
either of the following lines in in the Cisco IOS configuration:
Router#show running config
....
voice-port 1/1/1
!
mgcp
!
dial-peer voice 1 pots
service mgcpapp
port 1/1/1
or
Router#show running config
....
controller T1 1/1
framing sf
linecode ami
pri-group timeslots 1-24 service mgcp
or
Router#show running config
....
controller T1 1/1
framing sf
linecode ami
ds0-group 0 timeslots 1-24 type none service mgcp
The exact port numbers may vary in the configuration.
H.323 signaling-related vulnerabilities
+--------------------------------------
To determine whether H.323 is configured on an IOS device, look for
either of the following lines in the Cisco IOS configuration.
For Cisco bug ID CSCsi60004 this configuration is vulnerable:
Router#show running config | include proxy
proxy h323
For Cisco bug ID CSCsg70474 this configuration is vulnerable:
Router#show running config | include inspect
ip inspect name H323_protocol h323
ip inspect H323_protocol in
Real-time Transport Protocol-related vulnerabilities
+---------------------------------------------------
No particular configuration is required to enable RTP because this
protocol is invoked when audio or video information is transmitted.
H.323, MGCP, SIP, or H.320 protocols must be processing packets for a
router to process RTP packets.
Note: These vulnerabilities only affect sessions terminating or
originating on a device itself, not transit traffic; for example,
traffic that passes through a device, but is destined elsewhere is not
affected.
Facsimile reception vulnerability
+--------------------------------
The IOS device will listen to incoming facsimile transmission by
default if the Digital Signal Processor (DSP) is present. To determine
the presence of DSP on a device, execute the following command:
Note: This vulnerability only affects sessions terminating or
originating on a device itself, not transit traffic; for example,
traffic that passes through a device, but is destined elsewhere is not
affected.
Router#show voice dsp
DSP DSP DSPWARE CURR BOOT PAK TX/RX
TYPE NUM CH CODEC VERSION STATE STATE RST AI VOICEPORT TS ABORT PACK COUNT
==== === == ======== ======= ===== ======= === == ========= == ===== ===========
C542 001 01 None 7.4.1 IDLE idle 0 0 1/1/0 NA 0 598/607
C542 002 01 None 7.4.1 IDLE idle 0 0 1/1/1 NA 0 591/588
The above example shows that DSP is present on the device.
Products Confirmed Not Vulnerable
+--------------------------------
No other Cisco products are currently known to be affected by these
vulnerabilities. The following devices are known not to be affected:
* Cisco Unified Communications Manager (with the exception of
CSCsi80102)
* Cisco IP Phone
Details
=======
Details for vulnerabilities are grouped by category and impact.
SIP-related vulnerabilities
+--------------------------
SIP is a protocol that is used to establish, modify, and terminate
multimedia sessions. Most commonly, SIP is used for Internet telephony.
SIP call signaling can use UDP (User Datagram Protocol) or TCP
(Transport Control Protocol) as an underlying transport protocol. In
all cases vulnerabilities can be triggered by processing a malformed
SIP packet.
A malformed SIP packet may cause a vulnerable device to crash and may
allow arbitrary code to be executed. These vulnerabilities are
documented as the following Cisco Bug IDs:
* CSCsi80749 Crash while processing malformed SIP packet
* CSCsi80102 CUCM - Crash while processing malformed SIP packet
A malformed SIP packet may cause a memory leak and device crash. These
vulnerabilities are documented as the following Cisco Bug IDs:
* CSCsf11855 Crash while processing malformed SIP packet
* CSCeb21064 Crash while processing malformed SIP packet
* CSCse40276 Router crashed by malformed SIP message
* CSCse68355 Router crashed by malformed SIP packet
* CSCsf30058 Memory leak when processing malformed SIP message
* CSCsb24007 Memory corruption and unexpected reload on receiving a
SIP packet
* CSCsc60249 Crash while processing malformed SIP packet
MGCP-related vulnerabilities
+---------------------------
MGCP is a protocol for controlling media gateways from external call
control elements such as Media Gateway Controllers or Call Agents. A
media gateway is typically a network element that provides conversion
between the audio signals carried on telephone circuits and data
packets carried over the Internet or over other packet networks. In a
Cisco environment, a media gateway is used between the Cisco
Communications Manager and the Cisco router and servers as a voice
gateway.
A specially crafted MGCP packet can cause a vulnerable device to crash
or become unresponsive. The unresponsive device will not be able to
establish new telephone calls, and a reboot is required to restore
normal operation. These vulnerabilities are documented as the following
Cisco Bug IDs:
* CSCsf08998 MGCP stop responding after receiving malformed packet
* CSCsd81407 Router crash on receiving abnormal MGCP messages
H.323-signaling related vulnerabilities
+--------------------------------------
H.323 is an ITU (International Telecommunications Union) set of
recommendations for multimedia communication and signaling in networks
that use Internet Protocol.
A malformed H.323 packet can crash a vulnerable device. These
vulnerabilities are documented as the following Cisco Bug IDs:
* CSCsi60004 H323 Proxy Unregistration from Gatekeeper
* CSCsg70474 IOS FW with h323 inspect crashes when malformed H.323
packets received
Real-time Transport Protocol-related vulnerabilities
+---------------------------------------------------
RTP is a protocol that is designed to provide delivery services for
data with real-time characteristics, such as interactive audio and
video.
A malformed RTP packet can cause a vulnerable device to crash. These
vulnerabilities are documented as the following Cisco Bug IDs:
* CSCse68138 Issue in handling specific packets in VOIP RTP Lib
* CSCse05642 I/O memory corruption crash on a router
Facsimile reception vulnerability
+--------------------------------
Reception of a large packet can cause a vulnerable device to crash.
This vulnerability is documented as the following Cisco Bug ID:
* CSCej20505 Router hangs with overly large packet
Vulnerability Scoring Details
+----------------------------
Cisco is providing 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 1.0.
Cisco will provide a base and temporal score. Customers can then
compute environmental scores to assist in determining the impact of the
vulnerability in individual networks.
Cisco PSIRT will set the bias in all cases to normal. Customers are
encouraged to apply the bias parameter when determining the
environmental impact of a particular vulnerability.
CVSS is a standards-based scoring method that conveys vulnerability
severity and helps determine urgency and priority of response.
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

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
===========
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 the application of anti-spoofing
measures on the network edge. This action is required because all
vulnerable voice protocols can use UDP as transport protocol.
None of the listed vulnerabilities can be mitigated on Cisco Unified
Communications Manager. All mitigations must be done on adjacent
devices.
Users are advised to disable affected protocols if not required for
normal device operation. To prevent the router from processing SIP
packets, the user must execute the following commands:
Router(config)#sip-ua
Router(config-sip-ua)#no transport udp
Router(config-sip-ua)#no transport tcp
Router(config-sip-ua)#end
Note: When applying this workaround to devices that are processing
MGCP or H.323 calls, the device will not allow SIP processing to stop
while active calls are being processed. As a result, the workaround
should be implemented during a maintenance period when active calls can
be stopped.
Infrastructure Access Control Lists (iACL)
+-----------------------------------------
Although difficult to block traffic from transiting the network, it is
possible to identify traffic that should not target infrastructure
devices and block such traffic at the network border. Infrastructure
ACLs are considered a network security best practice and should be
considered as a long-term addition to good network security as well as
a workaround for this specific vulnerability. The ACL example shown
below should be included as part of the deployed infrastructure access
list that will protect all devices with IP addresses located within the
infrastructure IP address range.
A sample access list for devices running Cisco IOS is below:
!-- Permit SIP, MGCP, H.323 and RTP services from trusted hosts destined
!-- to infrastructure addresses.
access-list 150 permit tcp TRUSTED_HOSTS MASK INFRASTRUCTURE_ADDRESSES MASK eq 5060
access-list 150 permit tcp TRUSTED_HOSTS MASK INFRASTRUCTURE_ADDRESSES MASK eq 5061
access-list 150 permit udp TRUSTED_HOSTS MASK INFRASTRUCTURE_ADDRESSES MASK eq 5060
access-list 150 permit udp TRUSTED_HOSTS MASK INFRASTRUCTURE_ADDRESSES MASK eq 5061
access-list 150 permit udp TRUSTED_HOSTS MASK INFRASTRUCTURE_ADDRESSES MASK eq 2427
access-list 150 permit tcp TRUSTED_HOSTS MASK INFRASTRUCTURE_ADDRESSES MASK eq 1720
access-list 150 permit tcp TRUSTED_HOSTS MASK INFRASTRUCTURE_ADDRESSES MASK eq 11720
access-list 150 permit udp TRUSTED_HOSTS MASK INFRASTRUCTURE_ADDRESSES MASK eq 2517
access-list 150 permit udp TRUSTED_HOSTS MASK INFRASTRUCTURE_ADDRESSES MASK range 16384 32767
!-- Deny SIP, MGCP, H.323 and RTP packets from all other sources destined
!-- to infrastructure addresses.
access-list 150 deny tcp any INFRASTRUCTURE_ADDRESSES MASK eq 5060
access-list 150 deny tcp any INFRASTRUCTURE_ADDRESSES MASK eq 5061
access-list 150 deny udp any INFRASTRUCTURE_ADDRESSES MASK eq 5060
access-list 150 deny udp any INFRASTRUCTURE_ADDRESSES MASK eq 5061
access-list 150 deny udp any INFRASTRUCTURE_ADDRESSES MASK eq 2427
access-list 150 deny tcp any INFRASTRUCTURE_ADDRESSES MASK eq 1720
access-list 150 deny tcp any INFRASTRUCTURE_ADDRESSES MASK eq 11720
access-list 150 deny udp any INFRASTRUCTURE_ADDRESSES MASK eq 2517
access-list 150 deny udp any INFRASTRUCTURE_ADDRESSES MASK range 16384 32767
!-- Permit all other traffic to transit the device.
access-list 150 permit ip any any
interface serial 2/0
ip access-group 150 in
The white paper entitled "Protecting Your Core: Infrastructure
Protection Access Control Lists" presents guidelines and recommended
deployment techniques for infrastructure protection access lists. This
white paper can be obtained at the following link:
http://www.cisco.com/warp/public/707/iacl.html.
Control Plane Policing
+---------------------
Control Plane Policing (CoPP) can be used to block untrusted SIP (TCP
and UDP ports 5060 and 5061), MGCP (UDP port 2427), H.323 (TCP ports
1720 and 11720 and UDP port 2517), and RTP (UDP ports 16384 to 32767)
access to the device. 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. CoPP
protects the management and control planes by explicitly permitting
only authorized traffic sent to infrastructure devices and in
accordance with existing security policies and configurations. The
following example, which uses 192.168.100.1 to represent a trusted
host, can be adapted to the network:
!-- Deny SIP, MGCP, H.323 and RTP traffic from trusted hosts to all
!-- IP addresses configured on all interfaces of the affected device
!-- so that it will be allowed by the CoPP feature.
access-list 111 deny tcp host 192.168.100.1 any eq 5060
access-list 111 deny tcp host 192.168.100.1 any eq 5061
access-list 111 deny udp host 192.168.100.1 any eq 5060
access-list 111 deny udp host 192.168.100.1 any eq 5061
access-list 111 deny udp host 192.168.100.1 any eq 2427
access-list 111 deny tcp host 192.168.100.1 any eq 1720
access-list 111 deny tcp host 192.168.100.1 any eq 11720
access-list 111 deny udp host 192.168.100.1 any eq 2517
access-list 111 deny udp host 192.168.100.1 any range 16384 32767
!-- Permit all other SIP, MGCP, H.323 and RTP traffic sent to all
!-- IP addresses configured on all interfaces of the affected device
!-- so that it will be policed and dropped by the CoPP feature.
access-list 111 permit tcp any any eq 5060
access-list 111 permit tcp any any eq 5061
access-list 111 permit udp any any eq 5060
access-list 111 permit udp any any eq 5061
access-list 111 permit udp any any eq 2427
access-list 111 permit tcp any any eq 1720
access-list 111 permit tcp any any eq 11720
access-list 111 permit udp any any eq 2517
access-list 111 permit udp any any range 16384 32767
!-- Permit (Police or Drop)/Deny (Allow) all other Layer 3 and Layer 4
!-- 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-voice-class
match access-group 111
!-- Create a Policy-Map that will be applied to the
!-- Control-Plane of the device.
policy-map drop-voice-traffic
class drop-voice-class
drop
!-- Apply the Policy-Map to the Control-Plane of the
!-- device.
control-plane
service-policy input drop-voice-traffic
In the above CoPP example, the access control list entries (ACEs) that
match the potential exploit packets with the "permit" action result in
the exploit packets being discarded by the policy-map "drop" function.
Meanwhile, packets that match the "deny" action (not shown) are not
affected by the policy-map drop function.
Please note that in the 12.2S and 12.0S Cisco IOS trains the policy-map
syntax is different:
policy-map drop-voice-traffic
class drop-voice-class
police 32000 1500 1500 conform-action drop exceed-action drop
Additional information on the configuration and use of the CoPP feature
can be found at
