Description

The ACAP framework contains a Time-of-Check to Time-of-Use (TOCTOU) race condition, which could potentially lead to privilege escalation. This vulnerability can only be exploited if the Axis device is configured to allow the installation of unsigned ACAP applications, and if an attacker convinces the victim to install a malicious ACAP application.
