CVE-2013-3897 is a use-after-free vulnerability in the CDisplayPointer class within mshtml.dll in Microsoft Internet Explorer 6 through 11. The flaw is triggered by crafted JavaScript that abuses the onpropertychange event handler, causing Internet Explorer to access freed memory and resulting in memory corruption. Microsoft referred to it as an Internet Explorer Memory Corruption Vulnerability, and reporting in the provided content indicates it was exploited in the wild in 2013 and later incorporated into exploit kits including Sedkit and Grandsoft/Private EK. ESET’s reporting specifically notes Sedkit used this vulnerability against Internet Explorer 8 as part of a targeted exploit chain.

This repository contains a single Metasploit module implementing a browser-based exploit for CVE-2013-3897 (MS13-080), a use-after-free vulnerability in the CDisplayPointer object of Microsoft Internet Explorer 8 (and 7) on Windows XP SP3 and Windows 7. The exploit is delivered via a malicious HTTP server that serves crafted HTML and JavaScript to the victim's browser. The module leverages DOM manipulation and event handler abuse to trigger the vulnerability, allowing arbitrary code execution in the context of the browser process. The exploit supports customizable Metasploit payloads, enabling post-exploitation activities such as remote shells. The main fingerprintable endpoint is the HTTP path '/search?o=<osinfo>&d=<dllinfo>', which is used to deliver the exploit to the victim. The code is operational and weaponized for use within the Metasploit framework, and is not a detection script or fake exploit.
