# Exploit Title: FLIR AX8 Thermal Camera 1.32.16 - Remote Code Execution
# Author: Gjoko 'LiquidWorm' Krstic @zeroscience
# Date: 2018-10-14
# Vendor: FLIR Systems, Inc.
# Product web page: https://www.flir.com
# Affected version: Firmware: 1.32.16, 1.17.13, OS: neco_v1.8-0-g7ffe5b3, Hardware: Flir Systems Neco Board
# Tested on: GNU/Linux 3.0.35-flir+gfd883a0 (armv7l), lighttpd/1.4.33, PHP/5.4.14
# References:
# Advisory ID: ZSL-2018-5491
# Advisory URL: https://www.zeroscience.mk/en/vulnerabilities/ZSL-2018-5491.php

# Desc: The FLIR AX8 thermal sensor camera suffers from two unauthenticated
# command injection vulnerabilities. The issues can be triggered when calling
# multiple unsanitized HTTP GET/POST parameters within the shell_exec function
# in res.php and palette.php file. This can be exploited to inject arbitrary
# system commands and gain root remote code execution.
