Patch Available for "SQL Query Abuse" Vulnerability
Originally Posted: March 08, 2000

Summary
=======
Microsoft has released a patch that eliminates a security vulnerability in
Microsoft® SQL Server 7.0 and Microsoft Data Engine (MSDE) 1.0. The
vulnerability could allow the remote author of a malicious SQL query to
take unauthorized actions on a SQL Server or MSDE database or on the
underlying system that was hosting the SQL Server or MSDE database.

Frequently asked questions regarding this vulnerability and the patch can
be found at

Issue
=====
Microsoft SQL Server 7.0 and MSDE 1.0 perform incomplete argument validation
on certain classes of remotely submitted SQL statements. If a user is able
to submit a particular form of a SQL Select statement to SQL Server or MSDE,
it is possible to take actions on the SQL data base or, if the SQL Server or
MDSE is operating in an account with elevated privileges on the underlying
system, on the underlying operating system itself.

In order to exploit this vulnerability, a user would have to have the right
to submit queries to the SQL Server or MSDE via ODBC, OLE DB, or DB-Library
and be logged on using SQL Server Security. The user would not require any
special privileges beyond the right to submit SQL queries.

Affected Software Versions
==========================

Microsoft SQL Server Version 7.0 and Microsoft Data Engine (MSDE) 1.0.
