Description

This module exploits a vulnerability found in PhpTax, an income tax report
generator. When generating a PDF, the icondrawpng() function in drawimage.php
does not properly handle the pfilez parameter, which will be used in an exec()
statement, and then results in arbitrary remote code execution under the context
of the web server. Please note: authentication is not required to exploit this
vulnerability.
