Cisco Security Advisory: Cisco IOS Software Tunnels Vulnerability
Advisory ID: cisco-sa-20090923-tunnels
Revision 1.0
For Public Release 2009 September 23
+---------------------------------------------------------------------
Summary
=======
Cisco devices running affected versions of Cisco IOS Software are
vulnerable to a denial of service (DoS) attack if configured for IP
tunnels and Cisco Express Forwarding.
Cisco has released free software updates that address this
vulnerability.
This advisory is posted at:
http://www.cisco.com/warp/public/707/cisco-sa-20090923-tunnels.shtml
Note: The September 23, 2009, Cisco IOS Security Advisory bundled
publication includes eleven Security Advisories. Ten of the
advisories address vulnerabilities in Cisco IOS Software, and one
advisory addresses a vulnerability in Cisco Unified Communications
Manager. Each advisory lists the releases that correct the
vulnerability or vulnerabilities detailed in the advisory. The
following table lists releases that correct all Cisco IOS Software
vulnerabilities that have been published on September 23, 2009, or
earlier.

Affected Products
=================
Cisco devices are vulnerable when running an affected version of
Cisco IOS Software and configured for Generic Routing Encapsulation
(GRE), IPinIP, Generic Packet Tunneling in IPv6 or IPv6 over IP
tunnels with Cisco Express Forwarding enabled. The Cisco IOS Point to
Point Tunneling Protocol (PPTP) feature creates GRE tunnels that are
transparent to the user. Therefore systems configured for PPTP are
also vulnerable.
The Cisco multicast Virtual Private Network (MVPN) feature also
creates GRE tunnels that are transparent to the user, however MVPN
configurations are not vulnerable, unless there are other tunnels
that are configured explicitly.
Vulnerable Products
+------------------
A Cisco IOS device that is explicitly configured for a tunnel will
have a configuration similar to the following in the output of "show
running-config":
interface tunnel0
ip address [IP-address]
tunnel source [Tunnel-Source]
tunnel destination [Tunnel Destination]
An alternative method to identify devices that are configured for
tunnels is to use the "show interfaces" command. A sample output is
provided below:
Router#show interfaces | include Tunnel
Tunnel0 is up, line protocol is down
Hardware is Tunnel
[...]
Tunnel protocol/transport GRE/IP
!-- output truncated
A Cisco IOS device that is configured for Cisco Express Forwarding
will display the forwarding table in the output of "show ip cef"
output, as in the following example:
Router#show ip cef
Prefix Next Hop Interface
0.0.0.0/0 10.48.64.1 Ethernet0/0
0.0.0.0/32 receive
....
Cisco Express Forwarding is enabled by default in most Cisco IOS
Software versions.
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 7200 series device running
Cisco IOS Software release 12.3(19) with an installed image name of
C7200-JS-M:
7200#show version
Cisco Internetwork Operating System Software
IOS (tm) 7200 Software (C7200-JS-M), Version 12.3(19), RELEASE SOFTWARE
(fc2)

The following example identifies a Cisco 7300 series device running
Cisco IOS Software release 12.3(22) with an installed image name of
C7301-P-M:

Products Confirmed Not Vulnerable
+--------------------------------
Cisco IOS XR Software is not affected.
Cisco IOS XE Software is not affected.
IPsec and Dynamic Multipoint VPN (DMVPN) configurations that are
protected by IPsec are not affected.
MVPN configurations are not affected.
Multiprotocol Label Switching (MPLS) Traffic Engineering (TE) tunnels
are not affected.
No other Cisco products are currently known to be affected by these
vulnerabilities.
Details
=======
A tunnel protocol encapsulates a wide variety of protocol packet
types inside IP tunnels, creating a virtual point-to-point link
between internetworking devices over an IP network.
Cisco Express Forwarding is a Layer 3 IP switching technology. It
improves network performance and scalability for networks with high
and dynamic traffic patterns.
Devices that are running Cisco IOS Software and configured for GRE,
IPinIP, Generic Packet Tunneling in IPv6 or IPv6 over IP tunnels
tunnels and Cisco Express Forwarding may reload upon switching a
specially crafted malformed packets. Please note that using PPTP
creates GRE tunnels that are transparent to the end user so devices
configured for PPTP are vulnerable if they are configured on an
affected software version. Using MVPN also creates GRE tunnels that
are transparent to the end user. However MVPN configurations are not
vulnerable.
These vulnerabilities are addressed by the Cisco Bug IDs CSCsh97579,
CSCsq31776 and CSCsx70889 and have been assigned
Common Vulnerabilities and Exposures (CVE) IDs CVE-2009-2872 and
CVE-2009-2873.
Vulnerability Scoring Details
=============================

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
===========
Disabling Cisco Express Forwarding will mitigate this vulnerability.
It can be disabled in two ways:
Disabling Cisco Express Forwarding Globally
+------------------------------------------
Cisco Express Forwarding can be globally disabled by using the "no ip
cef" global configuration command.
Disabling Cisco Express Forwarding on Tunnel Interfaces
+------------------------------------------------------
Cisco Express Forwarding can also be disabled on individual tunnel
interfaces. To be effective, it must be disabled on all tunnel
interfaces configured on an affected device. Cisco Express Forwarding
can be disabled on individual interfaces as shown in the following
example:
interface Tunnel [interface-ID]
no ip route-cache cef
Note: Disabling Cisco Express Forwarding may have significant
performance impact and is not recommended.
Additional mitigations that can be deployed on Cisco devices in the
network are available in the Cisco Applied Mitigation Bulletin
companion document for this advisory, which is available at the
following link:
http://www.cisco.com/warp/public/707/cisco-amb-20090923-tunnels.shtml
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@xxxxxxxxx or security-alert@xxxxxxxxx for
software upgrades.
Customers with Service Contracts
+-------------------------------
Customers with contracts should obtain upgraded software through
their regular update channels. 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). TAC contacts are as follows.
* +1 800 553 2447 (toll free from within North America)
* +1 408 526 7209 (toll call from anywhere in the world)
* e-mail: tac@xxxxxxxxx
Customers should have their product serial number available and be
prepared to give the URL of this notice as evidence of entitlement to
a free upgrade. Free upgrades for non-contract customers must be
requested through the TAC.
