Cisco Security Advisory: Cisco IOS Next Hop Resolution Protocol Vulnerability

Advisory ID: cisco-sa-20070808-nhrp

http://www.cisco.com/warp/public/707/cisco-sa-20070808-nhrp.shtml

Revision 1.0

For Public Release 2007 August 08 1600 UTC (GMT)

- -----------------------------------------------------------------------

Summary
=======

The Cisco Next Hop Resolution Protocol (NHRP) feature in Cisco IOS
contains a vulnerability that can result in a restart of the device or
possible remote code execution.

NHRP is a primary component of the Dynamic Multipoint Virtual Private
Network (DMVPN) feature.

NHRP can operate in three ways: at the link layer (Layer 2), over
Generic Routing Encapsulation (GRE) and multipoint GRE (mGRE) tunnels
and directly on IP (IP protocol number 54). This vulnerability affects
all three methods of operation.

NHRP is not enabled by default for Cisco IOS.

This vulnerability is addressed by Cisco bug IDs CSCin95836 
for non-12.2 mainline releases and CSCsi23231 for 12.2 mainline releases.

This advisory is posted at 
http://www.cisco.com/warp/public/707/cisco-sa-20070808-nhrp.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
=================

Vulnerable Products
+------------------

Cisco devices running IOS that are configured for NHRP functionality
are affected. NHRP is also used in conjunction with the DMVPN feature.

Affected devices may have the following command in the running
configuration:

                ip nhrp network-id <ID>
                

After the above command is configured, simply removing the command from
the running configuration is not sufficient to disable the NHRP
service. Customers can check the output of the following command to see
if the NHRP process is enabled:

    router#show processes | include NHRP

      42 Mwe   F8B8CC           24         76     315 7836/12000  0 NHRP


If the preceding command displays the NHRP process, NHRP is running on
the IOS device.

Customers who do not have NHRP configured but see the process in the
process table can take the following action to eliminate their
exposure:

Ensure that NHRP is not configured in the device's startup
configuration and reload the device. After the device is restarted with
NHRP removed from the configuration, the NHRP process will not be
running.

Products Confirmed Not Vulnerable
+--------------------------------

  * Cisco devices that do not run Cisco IOS are not affected.
  * Cisco devices that are running Cisco IOS XR are not affected.

No other Cisco devices are known to be affected.

Details
=======

NHRP is a standards-based protocol that is aimed at providing Layer 2
to Layer 3 resolution for Nonbroadcast Multiaccess networks (NBMA).

Network devices and hosts can use NHRP to discover the addresses of
other devices connected to an NBMA network.

For more information on NHRP, see 
http://www.cisco.com/en/US/products/ps6350/products_configuration_guide_chapter09186a0080435815.html

NHRP is an open standard and the public RFC is on the web at:

http://www.rfc-editor.org/rfc/rfc2332.txt 

NHRP has extended uses in DMVPNs, can be carried in GRE and mGRE
tunnels or can be transported directly within IP datagrams as IP
protocol number 54.

Workarounds are available for protecting routers from NHRP packets sent
over GRE or mGRE tunnels or sent as NHRP directly in IP datagrams.

No workarounds exist for blocking Layer 2 NHRP packets. However, Layer
2 NHRP packets are not routable and must be sent by a Layer 2-adjacent
device.

This vulnerability was addressed by two different bug IDs. A Cisco IOS
release only needs to contain one of these bug fixes to be repaired for
this vulnerablility. The bug IDs are CSCin95836 (for non-12.2 mainline 
releases) and CSCsi23231 (for 12.2 mainline releases).

Vulnerability Scoring Details
+----------------------------

Cisco is providing scores for the vulnerability 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 a 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.

Impact
======

Successful exploitation of the vulnerability may result in a restart of
the device or remote code execution. Repeated exploitation may result
in an extended denial of service (DoS) condition.

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.
