CVE-2006-3439 is a stack-based buffer overflow vulnerability in the Server Service of Microsoft Windows 2000 SP4, XP SP1 and SP2, and Server 2003 SP1. The vulnerability is triggered by a specially crafted RPC message, allowing remote attackers, including unauthenticated users, to execute arbitrary code with SYSTEM privileges. This vulnerability is distinct from CVE-2006-1314 and was actively exploited at the time of disclosure.

This repository contains a single Metasploit module implementing a remote exploit for the MS06-040 vulnerability (CVE-2006-3439) in Microsoft Windows Server Service (NetApi32.dll). The exploit targets a stack buffer overflow in the CanonicalizePathName() function, reachable via the NetpwPathCanonicalize RPC call over SMB. The module is weaponized, supporting customizable payloads (up to 370 bytes) and multiple Windows targets (NT 4.0, 2000 SP0-SP4, XP SP0-SP1, 2003 SP0). It automatically detects the target OS version and adjusts the exploit accordingly. The attack vector is network-based, requiring access to the SMB service (TCP ports 445 or 139). The exploit communicates with the target using DCERPC over named pipes (default: BROWSER or SRVSVC). Successful exploitation results in arbitrary code execution as SYSTEM; failed attempts may cause denial of service or system reboot. The code is written in Ruby and is structured as a standard Metasploit module.
