Cisco Security Advisory: Cisco IOS Software Multicast Source Discovery
Protocol Vulnerability
Advisory ID: cisco-sa-20120328-msdp
Revision 1.0
For Public Release 2012 March 28 16:00 UTC (GMT)
+--------------------------------------------------------------------
Summary
=======
A vulnerability in the Multicast Source Discovery Protocol (MSDP)
implementation of Cisco IOS Software and Cisco IOS XE Software could
allow a remote, unauthenticated attacker to cause a reload of an
affected device. Repeated attempts to exploit this vulnerability could
result in a sustained denial of service (DoS) condition.
Cisco has released free software updates that address this
vulnerability. Workarounds that mitigate this vulnerability are
available. This advisory is available at the following link:
http://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20120328-msdp
Note: The March 28, 2012, Cisco IOS Software Security Advisory bundled
publication includes nine 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 March 2012
bundled publication.
Individual publication links are in "Cisco Event Response: Semi-Annual
Cisco IOS Software Security Advisory Bundled Publication" at the
following link:

Affected Products
=================
Vulnerable Products
+------------------
The following products are affected by this vulnerability:
+ Cisco IOS Software
+ Cisco IOS XE Software
To determine whether a Cisco IOS or Cisco IOS XE Software release 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 12.4(20)T with an installed image name of
C1841-ADVENTERPRISEK9-M:
Router#show version
Cisco IOS Software, 1841 Software (C1841-ADVENTERPRISEK9-M), Version 12.4(20)T, RELEASE SOFTWARE (fc3)

Products Confirmed Not Vulnerable
+--------------------------------
Cisco IOS XR Software is not affected by this vulnerability. No other
Cisco products are currently known to be affected by this vulnerability.
Details
=======
MSDP is the protocol used to connect multiple Protocol Independent
Multicast sparse mode (PIM-SM) domains. MSDP allows multicast sources
for a group to be known to all rendezvous points (RPs) in different
domains. An RP runs MSDP over TCP to discover multicast sources.
An RP in a PIM-SM domain has an MSDP peering relationship with
MSDP-enabled routers in another domain. The peering relationship occurs
over a TCP connection, where primarily a list of sources sending to
multicast groups is exchanged. The TCP connections between RPs are
achieved by the underlying routing system. The receiving RP uses the
source lists to establish a source path.
The purpose of this topology is to have domains discover multicast
sources in other domains. If the multicast sources are of interest to a
domain that has receivers, multicast data is delivered over the normal,
source-tree building mechanism in PIM-SM.
An MSDP packet containing encapsulated Internet Group Management
Protocol (IGMP) data, received from an external MSDP-configured peer
router, can cause an affected device to reload. This vulnerability can
only be exploited if the router is explicitly joined to the multicast
group. The MSDP packet destination address is a unicast address and
can be addressed to any IP address on the affected device, including
loopback addresses.
Transit traffic will not trigger this vulnerability.
A vulnerable interface configuration contains an explicitly joined
multicast group. Some example configurations that permit exploitation of
this vulnerability are:
!--- Interface configured for SAP Listener Support (a common
multicast group)
interface GigabitEthernet0/0
ip address 192.168.0.1 255.255.255.0
ip pim sparse-mode
ip sap listen
!--- Interface configured to join a multicast group
interface GigabitEthernet0/0
ip address 192.168.0.1 255.255.255.0
ip pim sparse-mode
ip igmp join-group 224.2.127.254
You can also use the "show igmp interface" command to determine if an
interface is joined to a multicast group.
RouterA#show ip igmp interface
GigabitEthernet0/0 is up, line protocol is up
Internet address is 192.168.0.1/24
IGMP is enabled on interface
Current IGMP host version is 2
Current IGMP router version is 2
IGMP query interval is 60 seconds
IGMP querier timeout is 120 seconds
IGMP max query response time is 10 seconds
Last member query count is 2
Last member query response interval is 1000 ms
Inbound IGMP access group is not set
IGMP activity: 2 joins, 0 leaves
Multicast routing is disabled on interface
Multicast TTL threshold is 0
Multicast groups joined by this system (number of users):
224.2.127.254(2) 239.255.255.255(1)
This vulnerability is documented in Cisco bug ID CSCtr28857. This
vulnerability has been assigned Common Vulnerabilities and Exposures
(CVE) ID CVE-2012-0382.
Vulnerability Scoring Details
=============================
Cisco has scored the vulnerabilities in this advisory based on the
Common Vulnerability Scoring System (CVSS). The CVSS scoring in this
security advisory is in accordance with CVSS version 2.0.
CVSS is a standards-based scoring method that conveys vulnerability
severity and helps organizations determine the urgency and priority
of a response.
Cisco has provided a base and temporal score. Customers can also compute
environmental scores that help determine the impact of the vulnerability
in their own networks.
Cisco has provided additional information regarding CVSS at the
following link:
http://www.cisco.com/web/about/security/intelligence/cvss-qandas.html
Cisco has also provided a CVSS calculator to compute the environmental
impact for individual networks at the following link:
http://intellishield.cisco.com/security/alertmanager/cvss
* CSCtr28857 ("MSDP-peered Router joined to a multicast group may crash")
CVSS Base Score - 7.1
Access Vector - Network
Access Complexity - Medium
Authentication - None
Confidentiality Impact - None
Integrity Impact - None
Availability Impact - Complete
CVSS Temporal Score - 6.4
Exploitability - Functional
Remediation Level - Workaround
Report Confidence - Confirmed
Impact
======
Successful exploitation of this vulnerability may cause the affected
device to reload. Repeated exploitation may result in a sustained DoS
condition.
Software Versions and Fixes
===========================
When considering software upgrades, customers are advised to
consult the Cisco Security Advisories and Responses archive at
http://www.cisco.com/go/psirt and review subsequent advisories to
determine exposure and a complete upgrade solution.
In all cases, customers should ensure that the devices to be upgraded
contain sufficient memory and confirm that current hardware and
software configurations will continue to be supported properly by the
new release. If the information is not clear, customers are advised
to contact the Cisco Technical Assistance Center (TAC) or their
contracted maintenance providers.
Cisco IOS Software
+-----------------
Each row of the following Cisco IOS Software table corresponds to a
Cisco IOS Software train. If a particular train is vulnerable, the
earliest releases that contain the fix are listed in the First Fixed
Release column. The First Fixed Release for All Advisories in the
March 2012 Bundled Publication column lists the earliest possible
releases that correct all the published vulnerabilities in the Cisco
IOS Software Security Advisory bundled publication. Cisco recommends
upgrading to the latest available release, where possible.
The Cisco IOS Software Checker allows customers to search for Cisco
Security Advisories that address specific Cisco IOS Software
releases. This tool is available on the Cisco Security Intelligence
Operations (SIO) portal at:
