Description

This module exploits a php unserialize() vulnerability in Invision IP.Board
code under the context of the webserver user.

The dangerous unserialize() exists in the '/admin/sources/base/core.php' script,
which is called with user controlled data from the cookie. The exploit abuses the
__destruct() method from the dbMain class to write arbitrary PHP code to a file on
the Invision IP.Board web directory.

The exploit has been tested successfully on Invision IP.Board 3.3.4.
