Detailsinfo

A vulnerability classified as problematic has been found in Microsoft SQL Server 7.0/2000 (Database Software). This affects the function xp_proxiedmetadata. The manipulation with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as 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. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

The xp_proxiedmetadata function in Microsoft SQL Server 2000 and 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 published 01/09/2001 by Chris Anley with Microsoft as not defined posting (Bugtraq). The advisory is shared at marc.theaimsgroup.com. This vulnerability is uniquely identified as CVE-2000-1087. The exploitability is told to be easy. An attack has to be approached locally. No form of authentication is needed for exploitation. Technical details and a public exploit are known.

A public exploit has been developed in ANSI C. The exploit is shared for download at securityfocus.com. It is declared as proof-of-concept.
