# Exploit Title: YouPHPTube <= 7.4 - Remote Code Execution  
# Google Dork: intext:"Powered by YouPHPTube"  
# Date: 29 August 2019  
# Exploit Author: Damian Ebelties (https://zerodays.lol/)  
# Vendor Homepage: https://www.youphptube.com/  
# Version: <= 7.4  
# Tested on: Ubuntu 18.04.1  
  
YouPHPTube before 7.5 does no checks at all if you wanna generate a new  
config file. We can use this to generate our own config file with our  
own (malicious) code.  
  
All you need is a MySQL server that allows remote connections.  
  
Fixed by the following commit:
