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.

Workarounds
===========

Customers who do not need NHRP functionality may disable the NHRP
service and eliminate the exposure to this vulnerability.

For customers who require NHRP functionality, this section provides
some workarounds to help reduce exposure.

If NHRP is required, the only complete resolution to this issue is to
upgrade to a fixed version of software.

Additional mitigations that can be deployed on Cisco devices within the
network are discussed in the Cisco Applied Intelligence companion
document for this advisory, which is available at the following link:

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

Because this attack can be sent from spoofed source addresses,
anti-spoofing techniques are required for the workarounds in this
section to be most effective.

Infrastructure ACLs
+------------------

Although it is often difficult to block traffic transiting the network,
it is possible to identify traffic that should never be allowed to
target infrastructure devices and block that traffic at the border of
the network. 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 following ACL example should be included as part of
the deployed infrastructure access list that will protect all devices
with IP addresses in the infrastructure IP address range.


!--- Permit NHRP/GRE services from trusted hosts destined
!--- to infrastructure addresses.


access-list 150 permit 47 TRUSTED_HOSTS MASK INFRASTRUCTURE_ADDRESSES MASK
access-list 150 permit 54 TRUSTED_HOSTS MASK INFRASTRUCTURE_ADDRESSES MASK


!--- Deny NHRP/GRE packets from all other sources destined
!--- to infrastructure addresses.


access-list 150 deny 47 any INFRASTRUCTURE_ADDRESSES MASK
access-list 150 deny 54 any INFRASTRUCTURE_ADDRESSES MASK


!--- 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 is on the web at

http://www.cisco.com/en/US/tech/tk648/tk361/technologies_white_paper09186a00801a1a55.shtml

Control Plane Policing
+---------------------

Control Plane Policing (CoPP) can be used to block untrusted NHRP (IP
protocol number 54) and GRE (IP protocol number 47) access to the
affected device. Cisco IOS Software releases 12.0S, 12.2SX, 12.2S,
12.3T, 12.4, and 12.4T support the CoPP feature. Administrators can
configure CoPP on a device to help protect the management and control
planes. Configuring CoPP can minimize the risk and effectiveness of
direct infrastructure attacks by explicitly permitting only authorized
traffic sent to infrastructure devices in accordance with existing
security policies and configurations. Administrators can adapt the
following example to their networks.


!--- Deny NHRP (IP protocol number 54) and GRE (IP protocol number 47)
!--- 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 54 TRUSTED_ADDRESSES MASK any
access-list 111 deny 47 TRUSTED_ADDRESSES MASK any

!
!--- Permit all other NHRP (IP protocol number 54) and GRE (IP protocol
!--- number 47) 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 54 any any
access-list 111 permit 47 any any

!
!--- Permit (Police or Drop)/Deny (Allow) all other Layer3
!--- and Layer4 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.

In the preceding CoPP example, the access control list entries (ACEs)
that match the potential exploit packets with the "permit" action
result in the discarding of these packets by the policy-map "drop"
function, whereas 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 Software trains, the policy-map syntax is
different:

policy-map drop-NHRP-traffic
class drop-NHRP-class
police 32000 1500 1500 conform-action drop exceed-action drop

Obtaining Fixed Software
========================

Cisco will make free software available to address this vulnerability
for affected customers. This advisory will be updated as fixed software
becomes available. 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/public/sw-license-agreement.html, or as otherwise
set forth at Cisco.com Downloads at
http://www.cisco.com/public/sw-center/sw-usingswc.shtml.

Do not contact either "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 agreement 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 who do not hold a Cisco
service contract and customers who purchase through third-party vendors
but are unsuccessful at obtaining fixed software through their point of
sale should get their 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

Have your product serial number available and give the URL of this
notice as evidence of your entitlement to a free upgrade. Free upgrades
for non-contract customers must be requested through the TAC.

Refer to http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml
for additional TAC contact information, including special localized
telephone numbers and instructions and e-mail addresses for use in
