CVE-2013-3918 is an out-of-bounds write vulnerability in the Microsoft Windows InformationCardSigninHelper ActiveX control. A crafted web page rendered by Internet Explorer can trigger memory corruption, allowing remote code execution or denial of service. Affected products include Windows XP, Windows Server 2003, Windows Vista, Windows Server 2008 and 2008 R2, Windows 7, Windows 8 and 8.1, Windows Server 2012 and 2012 R2, and Windows RT releases listed in Microsoft’s advisory. The vulnerability was exploited in the wild in November 2013.

This repository contains a single Metasploit module targeting CVE-2013-3918 (MS13-090), a vulnerability in the CardSpaceClaimCollection class of the icardie.dll ActiveX control on Windows XP with Internet Explorer 8. The exploit abuses an integer underflow in the remove() method, followed by memory corruption via add(), to achieve arbitrary code execution. The module is designed to be served to a victim's browser, exploiting the vulnerability when the victim visits a malicious web page. The exploit is operational and allows the attacker to execute arbitrary payloads (such as Meterpreter) on the target system. The main fingerprintable endpoints are the icardie.dll file and the CLSID {19916E01-B44E-4E31-94A4-4696DF46157B}. The code is written in Ruby and is structured as a typical Metasploit browser exploit module.
