Is this vulnerability remotely exploitable?

Yes. It is remotely exploitable through the LibreNMS web interface, but the attacker must be authenticated and able to reach the MAC accounting graph endpoint.

Does this require authentication or special privileges?

An attacker needs a valid LibreNMS user account with access to the MAC accounting graph functionality. No direct database access is required, but the web account must be able to invoke the vulnerable endpoint.

What is the safest general fix pattern?

Replace all string-concatenated SQL using the `sort` parameter with parameterized queries and a strict allowlist of permitted sort fields and directions, ensuring that user input is never directly embedded into SQL syntax.
