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 ( registered customers only) for non-12.2 mainline releases and CSCsi23231 ( registered customers only) 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 links are listed below:

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 ( registered customers only) (for non-12.2 mainline releases) and CSCsi23231 ( registered customers only) (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.
For further information about how Cisco IOS is built, numbered and maintained, please see the following URL: http://www.cisco.com/warp/public/620/1.html.
