Loading vulnerability…
A buffer overflow vulnerability exists in BlueCoat WinProxy before version 6.1a and in the web console access functionality of ProxyAV before version 2.4.2.3. The vulnerability is triggered by a long Host: header in HTTP requests, which can overflow a buffer and allow remote attackers to execute arbitrary code on the affected system.

This repository contains a single Metasploit exploit module targeting a buffer overflow vulnerability (CVE-2005-4085) in Blue Coat Systems WinProxy (versions <= 6.1 R1a) on Windows. The exploit works by sending a specially crafted HTTP request to the WinProxy service, specifically overflowing the port value in the Host header to trigger a SEH-based buffer overflow. The module allows the attacker to deliver a customizable payload (up to 600 bytes, avoiding specific bad characters) that can result in arbitrary code execution with the privileges of the WinProxy service. The exploit is network-based, targeting TCP port 80, and is operational in maturity, as it provides a working payload mechanism. The only code file is a Ruby Metasploit module, and no additional files or detection scripts are present.
