Advisory ID: cisco-sa-20030126-ms02-061

http://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20030126-ms02-061

Revision 1.5

For Public Release 2003 January 26 05:30  UTC (GMT)


Summary

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://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20030126-ms02-061.

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.

Vulnerable Products

  • Cisco CallManager 3.3(x)
  • Cisco Unity 3.x, 4.x
  • Cisco Building Broadband Service Manager 5.1

Products Confirmed Not Vulnerable

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

Details

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:

Vulnerability Scoring Details

Cisco has not provided scores for the vulnerabilities in this advisory based on the Common Vulnerability Scoring System (CVSS). At the time of original publication CVSS scoring in Cisco Security publications had not been adopted.

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 the following location:
http://www.cisco.com/tacpage/sw-center/telephony/crypto/voice-apps/.

Cisco Unity

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.

Cisco Building Broadband Service Manager

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 leaving cisco.com

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:

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.

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.
