Is this vulnerability remotely exploitable over the network?

Yes, but only through the authenticated web interface or API. Exploitation occurs via HTTP requests to functions that accept file paths, so it is remotely reachable within the network perimeter where FUXA is exposed.

Does an attacker need special privileges to exploit this?

Yes. The described scenario requires an authenticated attacker with administrative-level permissions or any role that has the ability to write or manage files on the server via FUXA.

What is the safest general fix pattern for this issue?

The safest pattern is to canonicalize all filesystem paths, ensure they remain within a predefined allowed root directory, and strictly reject any request that attempts to escape that root. Combine this with separation of executable code from user-writable locations and least-privilege filesystem permissions.
