CVE-2025-9524Network attack vector

Authenticated process crashes via malformed port.cgi input

Published Nov 11, 2025 · Updated Nov 14, 2025

Improper input validation in AXIS OS 6.50 through 12.6 allows remote authenticated users to crash VAPIX processes via port.cgi. The port.cgi endpoint accepts improperly validated input before processing it, but Axis has not disclosed the rejected type or parsing operation. A viewer-, operator-, or administrator-privileged service account is required; the bounded impact is a process crash that degrades device usability.
