Microsoft Security Advisory (961040)

Vulnerability in SQL Server Could Allow Remote Code Execution

Published: December 22, 2008

Microsoft is investigating new public reports of a vulnerability that could allow remote code execution on systems with supported editions of Microsoft SQL Server 2000, Microsoft SQL Server 2005, Microsoft SQL Server 2005 Express Edition, Microsoft SQL Server 2000 Desktop Engine (MSDE 2000), Microsoft SQL Server 2000 Desktop Engine (WMSDE), and Windows Internal Database (WYukon). Systems with Microsoft SQL Server 7.0 Service Pack 4, Microsoft SQL Server 2005 Service Pack 3, and Microsoft SQL Server 2008 are not affected by this issue.

Microsoft is aware that exploit code has been published on the Internet for the vulnerability addressed by this advisory. Our investigation of this exploit code has verified that it does not affect systems that have had the workarounds listed below applied. Currently, Microsoft is not aware of active attacks that use this exploit code or of customer impact at this time.

In addition, due to the mitigating factors for default installations of MSDE 2000 and SQL Server 2005 Express, Microsoft is not currently aware of any third-party applications that use MSDE 2000 or SQL Server 2005 Express which would be vulnerable to remote attack. However, Microsoft is actively monitoring this situation to provide customer guidance as necessary.

We are actively working with partners in our Microsoft Active Protections Program (MAPP) and our Microsoft Security Response Alliance (MSRA) programs to provide information that they can use to provide broader protections to customers.

Upon completion of this investigation, Microsoft will take the appropriate action to protect our customers, which may include providing a solution through a service pack, our monthly security update release process, or an out-of-cycle security update, depending on customer needs.

Customers who believe that they have been attacked can obtain security support at Get security support and should contact the national law enforcement agency in their country. Customers in the United States can contact Customer Service and Support at no charge using the PC Safety hotline at 1-866-PCSAFETY. Additionally, customers in the United States should contact their local FBI office or report their situation at Internet Crime Complaint Center.

Mitigating Factors:

This issue does not affect supported editions of Microsoft SQL Server 7.0 Service Pack 4, Microsoft SQL Server 2005 Service Pack 3, and Microsoft SQL Server 2008.

This vulnerability is not exposed anonymously. An attacker would need to either authenticate to exploit the vulnerability or take advantage of a SQL injection vulnerability in a Web application that is able to authenticate.

By default, MSDE 2000 and SQL Server 2005 Express do not allow remote connections. An authenticated attacker would need to initiate the attack locally to exploit the vulnerability.
