Is this vulnerability remotely exploitable over the internet?

It can be, but only if the router's administrative interface is exposed to the internet (for example, through remote management settings or misconfigured port forwarding). If management access is restricted to a local network, exploitation is typically limited to attackers with local network reach.

What level of access does an attacker need to exploit this issue?

An attacker needs network-level access to any interface that accepts root login (web admin panel, SSH, telnet, or other management protocols). No prior authentication is required beyond the ability to attempt logins using the hardcoded password.

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

Remove all hardcoded administrative credentials and design the device so that each unit either generates unique, strong credentials at manufacturing time or requires the user to set a secure password during initial setup, with no residual backdoor accounts.
