CVE-2012-1875 is a use-after-free vulnerability in Microsoft Internet Explorer 8, where the browser does not properly handle objects in memory. Specifically, remote attackers can execute arbitrary code by accessing a deleted object, exploiting the 'Same ID Property' flaw. The vulnerability allows attackers to bypass DEP/ASLR protections and achieve remote code execution via crafted web content. Exploitation in the wild has been observed, with evidence suggesting origins in Hong Kong. The Metasploit module for this vulnerability leverages msvcr71.dll to bypass mitigations.

This repository contains a single Metasploit module (ms12_037_same_id.rb) that exploits a memory corruption vulnerability (CVE-2012-1875) in Microsoft Internet Explorer 8 on Windows XP SP3, Windows 7 SP1, and Windows Vista SP2. The exploit is triggered when a victim visits a malicious web page hosted by the attacker. The module uses JavaScript heap spraying and a ROP chain to bypass DEP and execute arbitrary code (Metasploit payload) in the context of the browser. The exploit is weaponized, allowing the attacker to select and deliver a variety of payloads (such as reverse shells or Meterpreter sessions). The main attack vector is via the browser over HTTP, and the module is designed to be used within the Metasploit framework. The code is well-structured, with clear targeting logic based on the victim's User-Agent, and supports obfuscation of the JavaScript exploit code.
