CVE-2013-7331 is an information disclosure vulnerability in the Microsoft.XMLDOM ActiveX control present in Microsoft Windows 8.1 and earlier. The vulnerability allows remote attackers to determine the existence of local files, UNC share pathnames, intranet hostnames, and intranet IP addresses by analyzing error codes returned by the control, for example when accessing a res:// URL. This vulnerability was exploited in the wild in February 2014.

This repository contains a single Metasploit auxiliary module (ms14_052_xmldom.rb) targeting CVE-2013-7331, an information disclosure vulnerability in Microsoft Internet Explorer 8 and 9 on Windows. The module sets up a malicious HTTP server that serves obfuscated JavaScript to the victim. When a vulnerable version of IE visits the attacker's page, the script uses the Microsoft.XMLDOM ActiveX object to attempt to load XML from attacker-specified file paths on the victim's system. By analyzing error messages, the script can determine if specific files exist. Results are sent back to the attacker's server via a '/receiver/' HTTP endpoint. The attacker must provide a list of absolute file paths to probe. The module is operational and can be used to enumerate the existence of files on a victim's Windows system via a browser-based attack. The code is written in Ruby (Metasploit module) and JavaScript (payload).
