Is this vulnerability remotely exploitable over the internet?

It can be, if the router's management interface is exposed to the internet (e.g., remote administration enabled or port forwarding in place). If access is restricted to the local network, exploitation typically requires being on the same LAN or otherwise having network-level access.

Does an attacker need valid credentials to exploit this issue?

Not necessarily. Because the flaw lies in how token_id is used for access control, a crafted or replayed token in some cases may be enough to reach restricted functionality without a standard login, depending on the specific deployment and configuration.

What is the safest general fix pattern from a development perspective?

The safest pattern is to centralize authentication and authorization, ensuring all sensitive operations check server-side session state and role-based permissions. Tokens should be opaque, securely generated, bound to a session, and never used as the sole proof of privilege without server-side validation.
