A remote unauthenticated attacker may potentially be able to bypass Firewall 
restrictions implemented in EMC Network Configuration Manager by starting a 
rogue Zebedee client that connects to a Zebedee Server residing behind the 
firewall and may potentially be able to run malicious commands on service ports 
that do not provide authentication. 

CVSS v3 Base Score: 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N)
