Loading vulnerability…
A buffer overflow vulnerability exists in the Client Service for NetWare (CSNW) component of Microsoft Windows 2000 SP4, XP SP2, and Server 2003 up to SP1. The vulnerability is triggered when CSNW processes specially crafted messages, leading to memory corruption. This flaw allows remote attackers to execute arbitrary code in the context of the affected service.

This repository contains a single Metasploit exploit module targeting the MS06-066 vulnerability (CVE-2006-4688) in Microsoft Windows XP SP2's NetWare Workstation Service (nwwks.dll). The exploit leverages a stack buffer overflow via DCERPC over SMB, specifically targeting the 'nwwks' named pipe. The module allows the attacker to deliver a customizable payload (up to 1000 bytes) that executes as SYSTEM on the target. The exploit requires the NetWare client service to be running and the SMB service to be accessible. The code is written in Ruby and follows the standard Metasploit module structure, including options for specifying the SMB pipe. The main attack vector is network-based, exploiting a vulnerable DCERPC interface exposed over SMB. The module is operational and can be used to gain remote code execution on vulnerable systems.
This repository contains a single Metasploit module (ms06_066_nwapi.rb) that exploits a stack buffer overflow vulnerability in the nwapi32.dll module of the NetWare client service on Windows XP SP2. The exploit leverages the SMB/DCERPC protocol to deliver a payload via a crafted request to a specific DCERPC interface (UUID e67ab081-9844-3521-9d32-834f038001c0) over a named pipe (default: srvsvc). The module uses an egghunter technique to inject and locate the payload in memory, allowing for arbitrary code execution as SYSTEM. The exploit is operational and allows for customizable payloads up to 296 bytes. The repository is structured as a typical Metasploit exploit module, with all logic contained in a single Ruby file. No external endpoints or hardcoded IPs are present; the exploit targets network-accessible Windows XP SP2 systems running the vulnerable service.
