CVE-2023-21413Network attack vector

Administrator-level code execution via ACAP command injection

Published Oct 16, 2023 · Updated Jun 16, 2025

OS command injection in Axis Communications AB AXIS OS 10.5 through 11.5 allows remote authenticated users to execute arbitrary code. The application handling service incorporates attacker-controlled ACAP installation data into an operating-system command without neutralizing command elements. Exploitation requires an administrator-privileged account and installation of a crafted ACAP application, after which injected commands run on the Axis device.
