Stack-based Buffer Overflow in Cogent DataHub Web Server

This repository contains a single Metasploit module targeting a stack-based buffer overflow vulnerability (CVE-2013-0680) in the HTTP server of Cogent DataHub version 7.3.0 on Windows XP SP3. The exploit works by sending a specially crafted HTTP request with an overly long header, triggering the overflow and allowing arbitrary code execution. The module includes a check method to verify if the target is running the vulnerable service by requesting '/datahub.asp' and looking for a specific HTML title. The exploit method constructs a payload that overwrites the Structured Exception Handler (SEH) and delivers shellcode, leveraging Metasploit's payload system. The only file present is a Ruby script structured as a standard Metasploit exploit module, making use of the framework's HTTP client and SEH exploitation mixins. No hardcoded IPs or domains are present; the exploit targets the service at a user-specified host and port.
