Is this vulnerability remotely exploitable?

It can be, if the device's management interface is exposed over the network (e.g., via HTTP/HTTPS, SSH, or other protocols) and reachable from untrusted hosts, such as the public internet or guest networks.

What level of access does an attacker need to exploit this?

An attacker needs network or physical access sufficient to reach an authentication interface that accepts the root credentials. No prior authenticated access to the device is required beyond the use of the hardcoded password itself.

What is the safest general fix pattern for this kind of issue?

The safest pattern is to eliminate hardcoded passwords entirely, replacing them with unique per-device credentials, mandatory credential change on first use, or stronger authentication mechanisms such as cryptographic keys or certificates, combined with restricted management exposure.
