Is this vulnerability remotely exploitable?

Yes, it can be remotely exploitable if the aaPanel upload functionality is exposed over the network and reachable by an attacker, subject to any authentication or access controls in place.

Does an attacker need authenticated access to exploit this?

The requirement for authentication depends on how aaPanel is configured. If upload endpoints are restricted to authenticated users, an attacker would first need to gain or abuse valid credentials; if misconfigured or exposed, uploads may be possible without authentication.

What is the safest general fix pattern for this issue?

The safest pattern is to treat all uploaded files strictly as data: - enforce strong allowlists for file types, - store uploads outside of executable and web-accessible paths, - ensure they cannot be interpreted as code, - and apply least-privilege filesystem permissions to the upload directories.
