Loading vulnerability…
A type confusion vulnerability exists in Firefox before 1.0.5, Mozilla before 1.7.9, and Netscape 8.0.2 and 7.2, where the InstallVersion.compareTo function can be called with an object instead of a string. This can lead to an access violation and crash, and potentially allow remote attackers to execute arbitrary code.

This repository contains a single Metasploit module (mozilla_compareto.rb) that exploits a code execution vulnerability (CVE-2005-2265) in Mozilla Firefox (<1.0.5) and Mozilla Suite (<1.7.10) on Windows. The exploit works by serving a malicious HTML/JavaScript page to the victim's browser using Metasploit's built-in HTTP server. The JavaScript performs a heap spray and triggers the vulnerability via the InstallVersion object's compareTo() method, allowing arbitrary code execution. The module allows the attacker to select a payload, which is delivered as shellcode embedded in the served HTML. The exploit is operational and can be used to gain code execution on vulnerable systems when a user visits the attacker's page. The repository is structured as a typical Metasploit module, with the main logic in the on_request_uri and generate_html methods, and references to the official Mozilla advisory and CVE.
