No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

A signature verification bypass vulnerability exists in the command line interface of AOS-CX. Successful exploitation could allow an authenticated malicious actor with administrative privileges to execute arbitrary code on the underlying operating system, when certain pre-conditions outside of the attacker’s control are met.
