Affected Products
=================
Vulnerable Products
+------------------
Devices running affected versions of Cisco IOS Software and
configured with Authentication Proxy for HTTP(S) or Web
Authentication or the consent feature are vulnerable.
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 12.3(26) with an installed image name of
C2500-IS-L:
Router#show version
Cisco Internetwork Operating System Software
IOS (tm) 2500 Software (C2500-IS-L), Version 12.3(26), RELEASE SOFTWARE (fc2)

To determine if your device is configured with either Authentication
Proxy for HTTP(S), Web Authentication or the consent feature, log
into the device and issue the "show running-config" command.
The following example identifies firewall authentication proxy
services using the ip auth-proxy under the proxy rule name

Details
=======
The Cisco IOS Firewall authentication proxy feature allows network
administrators to apply specific security policies on a per-user
basis. With the authentication proxy feature, users can log in to the
network or access the Internet via HTTP, and their specific access
profiles are automatically retrieved and applied from a CiscoSecure
ACS, or other RADIUS or TACACS+ authentication server. The user
profiles are active only when there is active traffic from the
authenticated users. Web Authentication feature leverages the
underlying authentication proxy feature.
The consent feature for Cisco IOS routers enables organizations to
provide temporary Internet and corporate access to end users through
their wired and wireless networks by presenting a consent webpage.
The consent feature can be used with or without requesting a username
and password, but still leverages the underlying authentication proxy
feature.
This vulnerability allows a session to be permitted without first
being authenticated by the authentication proxy, or to be permitted
without first acknowledging the consent webpage. At least one
successfully authenticated session or accepted consent session must
exist for the vulnerability to be exposed. When this occurs, the
RADIUS or TACACS+ server will show subsequent users as authenticated,
all with the same username as the initial connection if performing
authentication, regardless of the authentication information provided
by the user and whether it was defined on the AAA server, and
regardless of whether the password was correct.
This vulnerability is caused by a race condition in the code, and
several conditions outside the control of a malicious user and must
be met before this vulnerability could be exploited.

Workarounds
===========
There are no workarounds for this vulnerability.
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@cisco.com or security-alert@cisco.com 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@cisco.com
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.
