# FLIR Systems FLIR Thermal Camera PT-Series (PT-334 200562) Remote Root Exploit
#
#
# Vendor: FLIR Systems, Inc.
# Product web page: http://www.flir.com
# Affected version: Firmware version: 8.0.0.64
# Software version: 10.0.2.43
# Release: 1.3.4 GA, 1.3.3 GA and 1.3.2
#
# Summary: FLIR's PT-Series of high-performance, multi-sensor pan/tilt cameras
# bring thermal and visible-light imaging together in a system that gives you
# video and control over both IP and analog networks. The PT-Series' precision
# pan/tilt mechanism gives you accurate pointing control while providing fully
# programmable scan patterns, radar slew-to-cue, and slew-to-alarm functions.
# PT-Series cameras define a new standard of performance with five models that
# provide full 640x480 thermal resolution.
#
# Desc: FLIR Camera PT-Series suffers from multiple unauthenticated remote command
# injection vulnerabilities. The vulnerability exist due to several POST parameters
# in controllerFlirSystem.php script when calling the execFlirSystem() function not
# being sanitized when using the shell_exec() PHP function while updating the network
# settings on the affected device. This allows the attacker to execute arbitrary system
# commands as the root user and bypass access controls in place.
