Loading vulnerability…
A stack-based buffer overflow exists in the Community Services Multiplexer (StMux.exe) component of IBM Lotus Sametime 7.5.1 CF1 and earlier, and 8.x before 8.0.1. The vulnerability is triggered by a crafted URL, which allows remote attackers to overflow a stack buffer and execute arbitrary code on the affected system. The flaw is present in the handling of incoming URL data by the StMux.exe process.

This repository contains a single Metasploit module targeting a stack buffer overflow vulnerability (CVE-2008-2499) in IBM Lotus Domino Sametime's STMux.exe service. The exploit works by sending a specially crafted POST request to the STMux.exe service (default TCP port 1533), overflowing a stack buffer and overwriting the Structured Exception Handler (SEH), allowing for arbitrary code execution. The module supports multiple versions of Lotus Sametime (7.5, 7.5.1, 8.0.0) on Windows Server 2000 SP4 and Windows Server 2003 SP1/SP2. The payload is customizable via Metasploit and can be up to 1024 bytes, with certain bad characters avoided. The module includes a check method to detect the presence of the vulnerable service by sending HTTP requests and looking for specific responses. The main attack vector is network-based, exploiting the STMux.exe service over TCP port 1533. The repository is structured as a single Ruby file compatible with the Metasploit framework, and all exploit logic is contained within this file.
