An OS command injection vulnerability in the management interface allows an authenticated administrator to execute arbitrary OS commands gaining access to the system.
Authenticated web GUI administrator can execute a command on the local system and then escalate privilege to the root user.
However, as by design web GUI administrators are allowed to use ssh keys to gain full console access, this finding has a low impact on our customers.
