Loading vulnerability…
Multiple stack-based buffer overflows exist in Novell GroupWise Messenger (GWIM) Client prior to version 2.0.3 HP1 for Windows. The vulnerability is triggered when the client processes spoofed server responses containing an overly long string after the NM_A_SZ_TRANSACTION_ID field name, leading to a stack overflow and potential execution of arbitrary code.

This repository contains a single Metasploit exploit module targeting a stack buffer overflow vulnerability (CVE-2008-2703) in the Novell GroupWise Messenger Client (versions 1.0 and 2.0) on Windows. The exploit works by acting as a malicious server that listens for incoming connections (default port 8300) from vulnerable clients. When a client connects, the module sends a specially crafted HTTP response containing a buffer overflow and a customizable payload. If the client is vulnerable, the payload is executed with the privileges of the client process, allowing for arbitrary code execution. The exploit is operational and allows for any Metasploit payload to be delivered, making it flexible for post-exploitation activities. The code is written in Ruby and follows the standard Metasploit module structure, with all logic contained in a single file.
