Loading vulnerability…
CVE-2011-0065 is a critical use-after-free vulnerability in Mozilla Firefox (before 3.5.19 and 3.6.x before 3.6.17) and SeaMonkey (before 2.0.14), specifically in the handling of the OBJECT element's mChannel property. The flaw resides in the OnChannelRedirect method of nsObjectLoadingContent, where mChannel is weakly referenced and can become a dangling pointer after garbage collection. This allows remote attackers to execute arbitrary code if a user visits a malicious web page that manipulates the OBJECT element, leading to use-after-free and subsequent memory corruption.

This repository contains a single Metasploit module (mozilla_mchannel.rb) that exploits a use-after-free vulnerability (CVE-2011-0065) in Mozilla Firefox 3.6.16 on Windows. The exploit is delivered via a malicious HTML page served by the Metasploit HTTP server. When a vulnerable user visits the page, JavaScript triggers the vulnerability using a crafted OBJECT element and the nsIChannelEventSink interface, leading to a dangling pointer (mChannel) and subsequent code execution. The exploit uses a heap spray and a minimal ROP chain to bypass DEP on Windows XP SP3, and leverages Java 6 for ASLR/DEP bypass on Windows 7. The payload is customizable and generated by Metasploit, allowing for arbitrary code execution (e.g., reverse shell, meterpreter). The module automatically detects the target OS and browser version via the User-Agent string and only attempts exploitation if the target is vulnerable. The only fingerprintable endpoint is the HTTP server that serves the exploit page. The repository is operational and ready for use within the Metasploit framework.
This repository contains a single Metasploit module: 'mozilla_mchannel.rb', which exploits a use-after-free vulnerability (CVE-2011-0065) in Mozilla Firefox 3.6.16 on Mac OS X (versions 10.6.6 through 10.7.3). The exploit is delivered via a malicious HTML page served by the Metasploit HTTP server. When a vulnerable Firefox user on a supported Mac OS X version visits the page, JavaScript triggers the vulnerability, allowing arbitrary shellcode (payload) execution. The module checks the User-Agent to ensure the target is running the correct Firefox and OS X versions. The payload is customizable via Metasploit and is delivered as shellcode embedded in JavaScript. The repository is structured as a single Ruby file implementing the exploit logic, with embedded JavaScript for the browser-based attack. No hardcoded IPs, domains, or external URLs are used for exploitation; the main fingerprintable endpoint is the HTTP server hosting the malicious page.
