CVE-2003-0533 is a stack-based buffer overflow in certain Active Directory service functions within LSASRV.DLL, part of the Local Security Authority Subsystem Service (LSASS) on multiple Microsoft Windows platforms, including Windows NT 4.0 SP6a, Windows 2000 SP2 through SP4, Windows XP SP1, Windows Server 2003, NetMeeting, Windows 98, and Windows ME. The flaw is triggered via the DCE/RPC interface when a crafted packet causes the DsRolerUpgradeDownlevelServer function to generate overly long debug entries for the DCPROMO.LOG log file, resulting in memory corruption on the stack. Successful exploitation allows remote, unauthenticated attackers to execute arbitrary code. The vulnerability was addressed by Microsoft in bulletin MS04-011 and was notably exploited in the wild by the Sasser worm.

This repository contains a single Metasploit module (Ruby file) that exploits the MS04-011 vulnerability (CVE-2003-0533) in the Microsoft LSASS service on Windows 2000 and Windows XP systems. The exploit leverages a stack buffer overflow in the DsRolerUpgradeDownlevelServer function, accessed via DCERPC over SMB (ports 445 or 139) using the \lsarpc named pipe. The module supports automatic and manual targeting for Windows 2000 and XP (English versions), and allows the user to specify a custom payload (e.g., reverse shell, Meterpreter). The exploit requires network access to the target's SMB service and valid credentials or guest access. If successful, it provides SYSTEM-level code execution on the target. The code is mature, weaponized, and part of the Metasploit framework, making it highly customizable and operationally ready.
