Description

Microsoft SQL Server is vulnerable to a buffer overflow by calling the function OpenDataSource with long parameter data, such as the following SQL query:

exec(SELECT * FROM OpenDataSource( ''Microsoft.Jet.OLEDB.4.0'',''Data Source=\"c:\'REPLICATE('A',2000);User ID=Admin;Password=;Extended properties=Excel 5.0'')...xactions')

To exploit this vulnerability, the user must first logon to the SQL server. This requires knowledge of a valid user id and password. Once logged on, the malicious user may be able to execute arbitrary commands with the privileges of the account used by the SQL server.
