Is this vulnerability remotely exploitable?

It can be, depending on network exposure. If the router's web admin interface is reachable from the internet or from an untrusted segment, attackers can exploit it remotely by sending crafted POST requests.

Does an attacker need to be authenticated to exploit this?

The issue sits in the login verification flow, which often processes requests before full authentication is established. In many deployments, an attacker only needs network-level access to the management interface, not valid credentials.

What is the safest general fix pattern for developers and firmware vendors?

Replace any direct use of request parameters in filesystem paths with a safe lookup mechanism, enforce strict validation and canonicalization of all path components, and ensure that file operations are limited to a well-defined, hard-coded directory.
