CVE-2014-8636 is a privilege-escalation vulnerability in the XrayWrapper implementation in Mozilla Firefox before 35.0 and SeaMonkey before 2.32. The flaw arises because XrayWrapper does not properly interact with a DOM object that has a named getter. Under unspecified conditions, this improper handling can allow remote attackers to cause arbitrary JavaScript code to execute with chrome privileges rather than normal web-content privileges. In Mozilla terminology, this represents a boundary failure between less-privileged web content and privileged browser chrome context.

This repository contains a single Metasploit module: 'firefox_proxy_prototype.rb', which exploits privilege escalation vulnerabilities in Mozilla Firefox versions 31-34 (CVE-2014-8636, CVE-2015-0802). The exploit abuses a bug in the XPConnect component to gain a reference to the privileged chrome:// window, enabling remote code execution. The attack is delivered via a malicious web page that requires the victim to click anywhere on the page to trigger the vulnerability. The module supports both JavaScript-based and native payloads, targeting multiple platforms (Java, Linux, OSX, Solaris, Windows) through the Firefox browser. The exploit leverages browser-specific endpoints such as 'chrome://browser/content/browser.xul' and 'data:' URLs to achieve code execution. The repository is structured as a single Ruby file compatible with the Metasploit framework, and its primary purpose is to provide a working exploit for the referenced Firefox vulnerabilities.
