CVE-2011-3400 is a type confusion vulnerability in Microsoft OLE (ole32.dll) on Windows XP SP2/SP3 and Windows Server 2003 SP2, specifically in the handling of the VT_VERSIONED_STREAM property in OLE compound files. The flaw allows remote attackers to execute arbitrary code by enticing a user to open or preview a specially crafted file (e.g., PPT, XLS, VSD) via Internet Explorer, Office Viewers, or Windows Explorer with thumbnail preview enabled. The vulnerability is trivial to exploit and does not require advanced exploitation techniques such as heap spraying.

This repository contains a single Metasploit module (ms11_093_ole32.rb) that exploits a type confusion vulnerability (CVE-2011-3400) in the OLE32 component of Microsoft Windows XP SP3. The exploit targets users running Internet Explorer 6 or 7 with Microsoft Visio Viewer 2010 installed. The module sets up a malicious HTTP server that serves a crafted Visio (.vsd) file and an HTML page with JavaScript heap spray. When a victim visits the attacker's page, the browser loads the malicious Visio file, triggering the vulnerability and allowing arbitrary code execution via a customizable Metasploit payload. The exploit is weaponized, allowing for easy payload customization and automated delivery through the Metasploit framework. The main attack vector is browser-based, requiring user interaction (visiting a malicious page), and the exploit leverages both network (HTTP) and file-based (malicious .vsd) endpoints.
