Loading vulnerability…
Belkin Bulldog Plus version 4.0.2 build 1219 contains a stack-based buffer overflow in its web-service authentication handler. An oversized HTTP Authorization header is copied into a fixed-size buffer without adequate length validation, causing memory corruption. A remote unauthenticated attacker may potentially execute code by sending a specially crafted request.

This repository contains a single Metasploit module (modules/exploits/windows/http/belkin_bulldog.rb) that exploits a stack buffer overflow vulnerability in the Belkin Bulldog Plus 4.0.2 build 1219 web service (CVE-2009-20009). The exploit targets systems running Windows XP SP3 English. The module sends a specially crafted HTTP GET request to the vulnerable service, placing the payload in the Authorization header using Basic authentication. The payload is customizable via Metasploit and allows for arbitrary code execution on the target system. The exploit is operational and leverages Metasploit's payload and encoding infrastructure. The only network endpoint involved is the HTTP service exposed by the vulnerable application, with the attack delivered via a raw HTTP request. The repository is structured as a single Ruby file compatible with the Metasploit framework.
