CVE-2024-0066Network attack vector

Sensitive traffic disclosure via unprotected O3C channel

Published Jun 18, 2024 · Updated Nov 8, 2024

Cleartext transmission in AXIS OS 5.51 through 11.9 allows attackers to read sensitive O3C device-to-server traffic. The O3C feature fails to protect sensitive traffic between the Axis device and O3C server, but Axis has withheld further mechanism details. The flaw is reachable only when O3C is used; it exposes confidentiality without a reported ability to alter traffic or interrupt the device.
