"FLIR AX8 thermal sensor cameras up to and including 1.46.16 are
vulnerable to Directory Traversal due to improper access restriction.
This vulnerability allows an unauthenticated, remote attacker to
obtain arbitrary sensitive file contents by uploading a specially
crafted symbolic link file. NOTE: The vendor has stated that with the
introduction of firmware version 1.49.16 (Jan 2023) the FLIR AX8
should no longer be affected by the vulnerability reported. Latest
firmware version (as of Oct 2025, was released Jun 2024) is 1.55.16.
