  Microsoft IIS Vulnerabilities in Cisco Products
------------------------------------------------------------------------

SUMMARY

This advisory describes a vulnerability that affects Cisco products and
applications that are installed on Microsoft operating systems
incorporating the use of the Internet Information Server (IIS), and is
based on the vulnerability of IIS, not due to a defect of the Cisco
product or application.

A number of vulnerabilities were discovered that enables an attacker to
execute arbitrary code or perform a denial of service against the server.
These vulnerabilities were discovered and publicly announced by Microsoft
in their Microsoft Security Bulletin MS02-018.

All Cisco products and applications that are using Microsoft IIS are
considered vulnerable.

DETAILS

Affected Products:
To determine if a product is vulnerable, review the list below. If the
software versions or configuration information are provided, then only
those combinations are vulnerable.
 * Cisco CallManager 3.0, 3.1, 3.2
 * Cisco ICS 7750
 * Cisco Unity
 * Cisco Building Broadband Service Manager 4.x, 5.x
 * Cisco uOne Enterprise Edition
 * Cisco Network Registrar (CNR)
 * Cisco Intelligent Contact Manager (ICM)

The following Cisco products may be installed on various web servers and
are vulnerable if installed on a Microsoft IIS server:
 * Cisco Collaboration Server (CCS)
 * Cisco Dynamic Content Adapter (DCA)
 * Cisco Media Blender (CMB)
 * TrailHead (Part of the Web Gateway solution)

Various Cisco Network Management products may be installed on Microsoft
platforms that may be running a vulnerable version of IIS. Much older
versions of CiscoWorks 2000 RWAN/CWSI Campus v2.x and Cisco Voice Manager
version 1.x are directly vulnerable because IIS was required as a part of
the installation. Such systems might be offering HTTP services on default
ports. These specific software packages are no longer supported, but are
included in this notice to alert customers who might still be using them.

Details:
Implementations of the Microsoft Internet Information Server are
vulnerable to buffer overflows and denial of service attacks. These
vulnerabilities can be exploited to execute arbitrary code on a computer
system or to disrupt normal operation of the server.

The vulnerabilities have been described in more detail at:
<http://www.microsoft.com/technet/security/bulletin/MS02-018.asp>
http://www.microsoft.com/technet/security/bulletin/MS02-018.asp.

Impact:
By gaining unauthorized access, an attacker can view and modify any part
of the operating system accessible with the privileges assigned to the web
server user possibly leading to a breach of confidentiality and integrity
of the system. By performing a denial of service attack, an attacker can
cause a disruption in availability of the web server.

Software Versions and Fixes:
A table containing a list of affected products and their fixes can be
found at:

Obtaining Fixed Software:
Cisco is offering free software upgrades to address this vulnerability for
all affected customers. Customers may only install and expect support for
the feature sets they have purchased.

Customers with service contracts should contact their regular update
channels to obtain any software release containing the feature sets they
have purchased. For most customers with service contracts, this means that
upgrades should be obtained through the Software Center on Cisco's
Worldwide Web site at <http://www.cisco.com> http://www.cisco.com.

Customers whose Cisco products are provided or maintained through a prior
or existing agreement with third-party support organizations such as Cisco
Partners, authorized resellers, or service providers should contact that
support organization for assistance with obtaining the free software
upgrade(s).

Customers who purchased directly 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 obtain fixed software by contacting the Cisco Technical
Assistance Center (TAC) using the contact information listed below. In
these cases, customers are entitled to obtain an upgrade to a later
version of the same release or as indicated by the applicable row in the
Software Versions and Fixes table (noted above).

Cisco 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

See <http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml>
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 various languages.

Please have your product serial number available and give the URL of this
notice as evidence of your entitlement to a free upgrade.

Please do not contact either "psirt@cisco.com" or
"security-alert@cisco.com" for software upgrades.

Workarounds:
Cisco is not aware of any available workarounds for these vulnerabilities
and strongly suggests the application of the recommended patches.
