Is this vulnerability remotely exploitable?

It can be, depending on deployment. If the NBI API is exposed to the internet or any untrusted network without additional protections, remote attackers may be able to exploit it without authentication.

What level of access does an attacker need?

An attacker typically only needs network-level access to the NBI endpoint; no valid GenieACS credentials are required if access control is not enforced at the application layer.

What is the safest general fix pattern?

The most robust pattern is to require strong authentication and explicit authorization checks for every NBI API operation, combined with least-privilege roles and constrained network exposure through dedicated management networks or API gateways.
