# TELSAT marKoni FM Transmitter 1.9.5 Root Command Injection PoC Exploit
#
#
# Vendor: TELSAT Srl
# Product web page: https://www.markoni.it
# Affected version: Markoni-D (Compact) FM Transmitters
# Markoni-DH (Exciter+Amplifiers) FM Transmitters
# Markoni-A (Analogue Modulator) FM Transmitters
# Firmware: 1.9.5
# 1.9.3
# 1.5.9
# 1.4.6
# 1.3.9
#
# Summary: Professional FM transmitters.
#
# Desc: The marKoni FM transmitters are susceptible to unauthenticated
# remote code execution with root privileges. An attacker can exploit
# a command injection vulnerability by manipulating the Email settings'
# WAN IP info service, which utilizes the 'wget' module. This allows
# the attacker to gain unauthorized access to the system with administrative
# privileges by exploiting the 'url' parameter in the HTTP GET request
# to ekafcgi.fcgi.
