Detailsinfo

A vulnerability was found in Microsoft SQL Server 7.0/2000 (Database Software) and classified as problematic. This issue affects the function xp_showcolv. The manipulation with an unknown input leads to a memory corruption vulnerability. Using CWE to declare the problem leads to CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. Impacted is availability. The summary by CVE is:

The xp_showcolv function in SQL Server and Microsoft SQL Server Desktop Engine (MSDE) does not properly restrict the length of a buffer before calling the srv_paraminfo function in the SQL Server API for Extended Stored Procedures (XP), which allows an attacker to cause a denial of service or execute arbitrary commands, aka the "Extended Stored Procedure Parameter Parsing" vulnerability.

The weakness was released 01/09/2001 by David Litchfield with Microsoft as not defined posting (Bugtraq). The advisory is shared at marc.theaimsgroup.com. The identification of this vulnerability is CVE-2000-1083. The exploitation is known to be easy. An attack has to be approached locally. No form of authentication is needed for a successful exploitation. Technical details as well as a public exploit are known.

A public exploit has been developed in ANSI C. The exploit is available at securityfocus.com. It is declared as proof-of-concept. We expect the 0-day to have been worth approximately $25k-$100k. The commercial vulnerability scanner Qualys is able to test this issue with plugin 19092 (Microsoft SQL Server Patch Not Installed (MS00-092)).

Upgrading eliminates this vulnerability. Furthermore it is possible to detect and prevent this kind of attack with TippingPoint and the filter 442.
