Flir Ax8 Firmware: Missing Authentication for Critical Functionality
CVE-2022-37062 is a high-severity missing authentication for critical functionality vulnerability in Flir Ax8 Firmware from Flir, with a CVSS 3.1 base score of 7.5 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. Affected Flir Ax8 Firmware versions: 1.46.16 and earlier. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 3.38% chance of exploitation within 30 days, higher than 89% of scored CVEs.
High severity with no evidence of exploitation so far.
What to do
- Check which version of Flir Ax8 Firmware you run against the affected versions below, and install the vendor's latest release.
- Read the advisory on flir.com for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description
All FLIR AX8 thermal sensor cameras version up to and including 1.46.16 are affected by an insecure design vulnerability due to an improper directory access restriction. An unauthenticated, remote attacker can exploit this by sending a URI that contains the path of the SQLite users database and download it. A successful exploit could allow the attacker to extract usernames and hashed passwords. 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.

The underlying weakness: Missing Authentication for Critical Functionality
The product does not perform any authentication for functionality that requires a provable user identity or consumes a significant amount of resources.
How developers prevent this class of flaw
- For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks entirely. Then, these modified values would be submitted to the server.
- Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid. For example, consider using libraries with authentication capabilities such as OpenSSL or the ESAPI Authenticator.
- When storing data in the cloud (e.g., S3 buckets, Azure blobs, Google Cloud Storage, etc.), use the provider's controls to require strong authentication for users who should be allowed to access the data.
