Summary
=======

This advisory describes a vulnerability that affects Cisco products and
applications that are installed on Microsoft operating systems incorporating
the use of the Microsoft SQL Server 2000 and is based on the vulnerability of
SQL Server 2000, not due to a defect of the Cisco product or application.

A number of vulnerabilities that have been discovered that enable 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 Bulletins MS02-039, MS02-056, and MS02-061.

All Cisco products and applications that are using unpatched Microsoft SQL
Server 2000 are considered vulnerable.

This advisory is available at
http://www.cisco.com/warp/public/707/cisco-sa-20030126-ms02-061.shtml.

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 3.3(x)
* Cisco Unity 3.x, 4.x
* Cisco Intelligent Contact Management (ICM) 5.0
* Cisco E-Mail Manager (CeM)
* Cisco Building Broadband Service Manager 5.0, 5.1

No other Cisco product is currently known to be affected by this vulnerability.

Details
=======

Implementations of the Microsoft SQL Server 2000 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/MS02-039.asp
http://www.microsoft.com/technet/security/bulletin/MS02-056.asp
http://www.microsoft.com/technet/security/bulletin/MS02-061.asp

Impact
======

According to Microsoft, the vulnerabilities range from an attacker gaining
additional privileges on a SQL server to gaining control over the SQL Server.
Additionally the MS SQL "Sapphire" Worm is known to exploit this same
vulnerability which can result in degraded network performance as the worm
attempts to propagate.

Software Versions and Fixes
===========================

Cisco CallManager

Customers running version 3.3(x) should install Cisco's cumulative SQL 2000
Hotfix, SQL2K-MS02-061.exe, from
http://www.cisco.com/tacpage/sw-center/telephony/crypto/voice-apps/.

Cisco Unity

Customers should install the Microsoft SQL 2000 Service Pack 2 (SP2) and
Security Rollup 1 (SRP1) "Q323875_SQL2000_SP2_en.EXE". Both are available
on the Microsoft website at the following location:
http://support.microsoft.com/default.aspx?scid=kb;en-us;Q316333&sd=tech

Cisco Intelligent Contact Management

This section will be updated within 24 hours with more details on patch
availability.

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

Where Cisco provides the operating system bundled with the product, Cisco is
offering free software upgrades to address these vulnerabilities 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/tacpage/sw-center/.

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: [email protected]

See 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 "[email protected]" or "[email protected]"
for software upgrades.

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

Cisco has published a companion document at
http://www.cisco.com/warp/public/707/cisco-sn-20030125-worm.shtml
which provides network based workarounds to mitigate the effects of these
vulnerabilities. Cisco also recommends applying the software based fixes to
affected devices to completely resolve the vulnerability.
