Vulnerability Note VU#682620

Original Release Date: 2002-07-25 | Last Revised: 2003-02-06

Overview

The Microsoft SQL Server contains a buffer overflow vulnerability that may allow remote attackers to execute arbitrary code with system privileges.

Description

The Microsoft SQL Server contains a buffer overflow vulnerability in the code used to process "Bulk Insert" queries. Bulk Insert queries allow the SQL user to supply a file containing records to be imported into the SQL database. If an attacker supplies a file with an excessively long filename, it is possible to overflow the application stack and alter the flow of execution, resulting in the execution of arbitrary code. Note that successful exploitation of this vulnerability requires Bulk Administrator or Administrator group privileges.

Impact

This vulnerability may allow remote attackers to execute arbitrary code with system privileges.
