CVE-2008-4844 is a use-after-free vulnerability in the CRecordInstance::TransferToDestination function within mshtml.dll (and addressed via updates to mshtml.dll/wmshtml.dll) in Microsoft Internet Explorer 5.01, 6, 6 SP1, and 7. The flaw is triggered through Data Source Object (DSO) binding/data binding code paths involving XML Island, XML DSOs, or Tabular Data Control (TDC) when processing a crafted HTML or XML document (e.g., demonstrated with nested SPAN or MARQUEE elements). Exploitation can result in remote arbitrary code execution and was observed exploited in the wild in December 2008.

This repository contains a single Metasploit module: 'ms08_078_xml_corruption.rb', which exploits a memory corruption vulnerability (CVE-2008-4844) in Microsoft Internet Explorer 7 on Windows. The exploit leverages a flaw in the data binding feature of IE, using a sophisticated .NET DLL memory corruption technique to achieve reliable code execution. The module sets up an HTTP server that serves a malicious HTML page and a dynamically generated DLL to the victim. When a vulnerable user visits the attacker's page, JavaScript and ActiveX are used to trigger the vulnerability, resulting in the execution of attacker-supplied shellcode. The payload is fully customizable via Metasploit, allowing for a variety of post-exploitation actions. The code is weaponized, as it is part of the Metasploit framework and supports flexible payload delivery. The main attack vector is through the browser, requiring user interaction (visiting a malicious site). The repository is well-structured, with all exploit logic contained in a single Ruby file following Metasploit conventions.
