CVE-2011-0073 is a critical remote code execution vulnerability in Mozilla Firefox (before 3.5.19 and 3.6.17) and SeaMonkey (before 2.0.14), caused by improper use of nsTreeRange data structures. Specifically, a dangling pointer in the nsTreeRange structure within the XUL nsTreeSelection element could be exploited by remote attackers through crafted web content or files. The vulnerability allowed attackers to control the value of mNext in nsTreeRange, leading to arbitrary code execution. The flaw was present in Firefox 3.6.13 on Windows XP SP3 and required user interaction to trigger, such as visiting a malicious page or opening a malicious file. The exploit could bypass DEP protections but was not 100% reliable. Firefox 4 and trunk versions were not affected due to prior architectural changes and removal of Web XUL support.

This repository contains a single Metasploit module (mozilla_nstreerange.rb) that exploits a dangling pointer vulnerability (CVE-2011-0073) in Mozilla Firefox versions 3.5.x and 3.6.x on Windows. The exploit is delivered via a malicious web page served by Metasploit's HTTP server. When a vulnerable Firefox browser visits the page, JavaScript code triggers the vulnerability in the nsTreeSelection component, leading to use-after-free and remote code execution. The module supports multiple targets, including direct attacks on Windows XP and attacks via Java if enabled, with various offsets for different Java versions. The payload is customizable and supports standard Metasploit shellcode, typically resulting in a remote shell or Meterpreter session. The exploit is weaponized, leveraging Metasploit's framework for payload delivery, session handling, and browser autopwn capabilities. The only fingerprintable endpoint is the HTTP server that serves the exploit to the victim's browser.
