CVE-2013-3918 is a remote code execution vulnerability in the InformationCardSigninHelper Class ActiveX control implemented in icardie.dll on multiple Microsoft Windows versions. The flaw is an out-of-bounds write that can be triggered when Internet Explorer instantiates the vulnerable ActiveX control while rendering attacker-supplied web content. A specially crafted web page can corrupt memory in the control, leading to application instability or controlled code execution in the context of the logged-in user. The vulnerability was exploited in the wild in 2013 and is also referred to as the InformationCardSigninHelper Vulnerability.

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.
