Microsoft SQL Server contains buffer overflows in several Database Consistency Checkers

Vulnerability Note VU#279323

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

Overview

Microsoft SQL Server ships with several administrative tools that allow database users to elevate their administrative privileges from a single database to all databases on the server.

Description

Microsoft SQL Server ships with several utilities known as Database Consistency Checkers (DBCCs). According to Microsoft Security Bulletin MS02-038, "DBCCs are command console utilities that allow maintenance and other operations to be performed on a SQL server." An unspecified subset of the DBCC utilities contain buffer overflows that allow users who have db_owner or db_ddladmin privileges on a single database to elevate their administrative privileges to the entire SQL server.

Impact

This vulnerability allows remote attackers to execute arbitrary code with the privileges of the SQL service account. If the privileges of the service account are elevated via VU#796313, this vulnerability may result in compromise of the server host.
