VLC Media Player 2.2.8 MKV Use-After-Free

Posted on 11 October 2018

This Metasploit module exploits a use-after-free vulnerability in VideoLAN VLC versions 2.2.8 and below. The vulnerability exists in the parsing of MKV files and affects both 32 bits and 64 bits. In order to exploit this, this module will generate two files: The first .mkv file contains the main vulnerability and heap spray, the second .mkv file is required in order to take the vulnerable code path and should be placed under the same directory as the .mkv file. This Metasploit module has been tested against VLC v2.2.8. Tested with payloads windows/exec, windows/x64/exec, windows/shell/reverse_tcp, windows/x64/shell/reverse_tcp. Meterpreter payloads if used can cause the application to crash instead.
