This advisory describes a vulnerability that affects Cisco products and applications incorporating the use of the Microsoft SQL Server 2000 or the Microsoft SQL Server 2000 Desktop Engine (MSDE 2000).
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 or MSDE 2000 are vulnerable.
This advisory is available at http://www.cisco.com/warp/public/707/cisco-sa-20030126-ms02-061.shtml.
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.
Implementations of the Microsoft SQL Server 2000 and MSDE 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/virus/alerts/slammer.asp 
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
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.
Customers running version 3.3(x) should install Cisco's cumulative SQL
2000 Hotfix, SQL2K-MS02-061.exe, from the following location:
http://www.cisco.com/tacpage/sw-center/telephony/crypto/voice-apps/.
Customers should follow the instructions found in http://www.cisco.com/warp/public/788/AVVID/unity3_4_slamworm.html for upgrading their Cisco Unity servers.
Software is now available on Cisco's website to patch BBSM 5.1. Version 5.0 and 5.2 are not vulnerable.
Before installing the security patch for this vulnerability, customers should install MSFIX1 and MSFIX2. Java Runtime 1.3.1 must also be installed after MSFIX1, but before MSFIX2.
Java Runtime 1.3.1_06 is available here:
http://java.sun.com/j2se/1.3/download.html
The patch is available at this location:
http://www.cisco.com/public/sw-center/sw-netmgmt.shtml
Instructions for installing service patches on BBSM can be found here:

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:
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 "psirt@cisco.com" or "security-alert@cisco.com" for software upgrades.
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.
This issue is being exploited actively and has been discussed in numerous public announcements and messages.
This is a Interim advisory. Although Cisco cannot guarantee the accuracy of all statements in this notice, all of the facts have been checked to the best of our ability.
