No, there is no CVE for running several years old firmware, with default or weak passwords and with ports open to the internet. If you had that you should not be managing routers in first place.

@ErrataRob NAT increases complexity of an attack. Instead of a direct connection you depend on the connection starting from the other side. In CVSS perspective this would be User Interaction Required and or Attack Complexity High. I think we can say it may help reduce severity or risk.…

@kevinriggle Hey @kevinriggle , Everyone should update it is a CVSS 10, but not everyone understands how CVSS works so the risk is not the same to all. Unless you opened your UniFi OS firewall to the internet (they are closed by default), the attack can only happen from inside your network.

Password Spray / Brute Force exists and will always exist. You are safe if you use long and strong passwords or even better instead of password you use public keys. if possible and connection only happens from a known network you can have a firewall blocking unknown sources.
