Detailsinfo

A vulnerability was found in Microsoft SQL Server 7.0/2000 (Database Software). It has been declared as problematic. Affected by this vulnerability is the function xp_peekqueue. The manipulation with an unknown input leads to a memory corruption vulnerability. The CWE definition for the vulnerability is 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. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

The xp_peekqueue 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 presented 01/09/2001 by Chris Anley with Microsoft as not defined posting (Bugtraq). It is possible to read the advisory at marc.theaimsgroup.com. This vulnerability is known as CVE-2000-1085. The exploitation appears to be easy. Attacking locally is a requirement. The exploitation doesn't need any form of authentication. Technical details and also a public exploit are known.

A public exploit has been developed in ANSI C. It is possible to download the exploit 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 450.

The vulnerability is also documented in the databases at X-Force (5622), Exploit-DB (20457), SecurityFocus (BID 2040†) and Vulnerability Center (SBV-38475†).
