Detailsinfo

A vulnerability was found in Microsoft Windows up to Server 2003 (Operating System) and classified as critical. This issue affects an unknown code of the component LSASS Request Handler. The manipulation with an unknown input leads to a stack-based overflow vulnerability. Using CWE to declare the problem leads to CWE-121. A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function). Impacted is confidentiality, integrity, and availability. The summary by CVE is:

Stack-based buffer overflow in certain Active Directory service functions in LSASRV.DLL of the Local Security Authority Subsystem Service (LSASS) in Microsoft Windows NT 4.0 SP6a, 2000 SP2 through SP4, XP SP1, Server 2003, NetMeeting, Windows 98, and Windows ME, allows remote attackers to execute arbitrary code via a packet that causes the DsRolerUpgradeDownlevelServer function to create long debug entries for the DCPROMO.LOG log file, as exploited by the Sasser worm.

The bug was discovered 04/13/2004. The weakness was shared 04/13/2004 by Yuji Ukai (DiGiT) with eEye Digital Security as MS04-011 as confirmed bulletin (Technet).

No form of authentication is needed for a successful exploitation. Technical details are unknown but a public exploit is available.

A public exploit has been developed in ZIP Archive and been published 3 weeks after the advisory. The exploit is available at users.volja.net. It is declared as highly functional. We expect the 0-day to have been worth approximately $25k-$100k. The vulnerability scanner Nessus provides a plugin with the ID 12205 (MS04-011: Microsoft Hotfix (credentialed check) (835732)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Windows : Microsoft Bulletins and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 90108 (Multiple Microsoft Windows Vulnerabilities (MS04-011)).
