CVE-2014-0307 is a use-after-free vulnerability in Microsoft Internet Explorer 9. The flaw exists due to improper handling of TextRange elements, where a specific sequence of manipulations can result in a dangling pointer. This allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) by enticing a user to visit a malicious web page.

This repository contains a single Metasploit module (ms14_012_textrange.rb) that exploits a use-after-free vulnerability (CVE-2014-0307) in Microsoft Internet Explorer 9 (specific MSHTML builds on Windows). The exploit is delivered via a malicious web page, which uses JavaScript and a crafted HTML structure to trigger the vulnerability and execute a ROP chain and shellcode payload. The module leverages Metasploit's BrowserExploitServer to serve the exploit to victims. The payload is customizable and typically provides remote code execution (such as a reverse shell) on the target system. The only fingerprintable endpoint is the 'ms-help:' protocol, used in the exploit's JavaScript. The repository is structured as a single Ruby file, following Metasploit's exploit module conventions, and is operational in maturity, requiring the victim to browse to the attacker's page with a vulnerable browser.
