Cisco Security Advisory: Cisco IOS Internet Key Exchange Vulnerability
Advisory ID: cisco-sa-20120328-ike
Revision 1.0
For Public Release 2012 March 28 16:00 UTC (GMT)
+--------------------------------------------------------------------
Summary
=======
The Cisco IOS Software Internet Key Exchange (IKE) feature contains a
denial of service (DoS) vulnerability.
Cisco has released free software updates that address this
vulnerability.
This advisory is available at the following link:
http://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20120328-ike
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
+------------------
Cisco devices that are running Cisco IOS Software are vulnerable when
they are configured to use IKE version 1 (IKEv1).
A number of features use IKEv1, including different Virtual Private
Networks (VPN) such as:
* LAN-to-LAN VPN
* Remote access VPN (excluding SSLVPN)
* Dynamic Multipoint VPN (DMVPN)
* Group Domain of Interpretation (GDOI)
There are two methods to determine if a device is configured for IKE:
* Determine if IKE ports are open on a running device
* Determine if IKE features are included in the device
configuration
Determine if IKE Ports are Open on a Running Device
+--------------------------------------------------
The preferred method to determine if a device has been configured for
IKE is to issue the "show ip sockets" or "show udp" exec command. If the
device has UDP port 500, UDP port 4500, UDP port 848, or UDP port 4848
open, it is processing IKE packets.
In the following example, the device is processing IKE packets in UDP
port 500 and UDP port 4500, using either IPv4 or IPv6:
router# show udp
Proto Remote Port Local Port In Out Stat TTY OutputIF
17 --listen-- 192.168.130.21 500 0 0 1001011 0
17(v6) --listen-- UNKNOWN 500 0 0 1020011 0
17 --listen-- 192.168.130.21 4500 0 0 1001011 0
17(v6) --listen-- UNKNOWN 4500 0 0 1020011 0
!--- Output truncated
router#
Determine if IKE Features are included in the Device Configuration
+-----------------------------------------------------------------
To determine if a Cisco IOS device configuration is vulnerable,
the administrator needs to establish whether there is at least one
configured feature that uses IKE. This can be achieved by using the
"show run | include crypto map|tunnel protection ipsec|crypto gdoi"
enable mode command. If the output of this command contains either
crypto map, tunnel protection ipsec, or, crypto gdoi then the device
contains an IKE configuration. The following example shows a device that
has been configured for IKE:
router# show run | include crypto map|tunnel protection ipsec|crypto gdoi
crypto map CM 100 ipsec-isakmp
crypto map CM
router#
Determine the Cisco IOS Software Release
+---------------------------------------
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 product that is running
Cisco IOS Software Release 15.0(1)M1 with an installed image name of
C3900-UNIVERSALK9-M:
Router> show version
Cisco IOS Software, C3900 Software (C3900-UNIVERSALK9-M), Version 15.0(1)M1, RELEASE SOFTWARE (fc1)

Products Confirmed Not Vulnerable
+--------------------------------
Cisco ASA 5500 Series Adaptive Security Appliance is not affected by
this vulnerability.
No other Cisco products are currently known to be affected by this
vulnerability.
Details
=======
The IKE protocol is used in the Internet Protocol Security (IPsec)
protocol suite to negotiate cryptographic attributes that will be
used to encrypt or authenticate the communication session. These
attributes include cryptographic algorithm, mode, and shared keys.
The end result of IKE is a shared session secret that will be used to
derive cryptographic keys.
Cisco IOS Software supports IKE for IPv4 and IPv6 communications.
IKE communication can use any of the following UDP ports:
* UDP port 500
* UDP port 4500, NAT Traversal (NAT-T)
* UDP port 848, Group Domain of Interpretation (GDOI)
* UDP port 4848, GDOI NAT-T
The IKEv1 feature of Cisco IOS Software contains a vulnerability that
could allow an unauthenticated, remote attacker to cause a reload of
an affected device.
An attacker could exploit this vulnerability using either IPv4 or
IPv6 on any of the listed UDP ports. Spoofing of packets that could
exploit this vulnerability is limited because the attacker needs to
either receive or have access to the initial response from the
vulnerable device.
This vulnerability is documented in Cisco bug ID CSCts38429 and has been
assigned Common Vulnerabilities and Exposures (CVE) ID CVE-2012-0381.
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
* CSCts38429 ("Cisco IOS Software IKE DoS vulnerability")
CVSS Base Score - 7.8
Access Vector - Network
Access Complexity - Low
Authentication - None
Confidentiality Impact - None
Integrity Impact - None
Availability Impact - Complete
CVSS Temporal Score - 6.4
Exploitability - Functional
Remediation Level - Official-Fix
Report Confidence - Confirmed
Impact
======
Successful exploitation of the vulnerability may cause the vulnerable
device to reload.
Software Versions and Fixes
===========================
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:
