CVE-2013-1347 is a use-after-free / improper object lifetime handling vulnerability in Microsoft Internet Explorer 8. The provided content identifies it as a CGenericElement object use-after-free flaw in which IE8 does not properly handle objects in memory, allowing an attacker to access an object that was either not properly allocated or had already been deleted. By triggering this memory corruption condition via malicious web content, a remote attacker can corrupt process memory and achieve arbitrary code execution. The vulnerability was exploited in the wild in May 2013, including watering-hole and exploit-kit-driven campaigns, and was associated with Microsoft bulletin MS13-038.

This repository contains a single Metasploit module implementing a weaponized exploit for CVE-2013-1347, a use-after-free vulnerability in Microsoft Internet Explorer 8. The exploit is delivered via a malicious HTTP server that serves specially crafted HTML and JavaScript to vulnerable clients. When a user with a vulnerable version of IE8 on Windows XP SP3, Vista, Server 2003, or Windows 7 visits the attacker's page, the exploit triggers a use-after-free in the CGenericElement object, allowing for arbitrary code execution. The module supports multiple targets and uses ROP chains tailored to the OS version. The payload is fully customizable via Metasploit, enabling the attacker to execute arbitrary code (such as a reverse shell or Meterpreter session) in the context of the browser process. The main entry point is the Ruby file 'modules/exploits/windows/browser/ie_cgenericelement_uaf.rb', which leverages Metasploit's HTTP server and browser autopwn capabilities. The only fingerprintable endpoint is the HTTP server hosted by the attacker, which serves the exploit to visiting clients.
