Is this vulnerability remotely exploitable over the internet?

Typically, exploitation is limited to the local network, as the router's web management interface is usually bound to the LAN side. However, if remote management is exposed to the internet or if the router is reachable via some upstream misconfiguration, the risk can extend beyond the local network.

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

The attacker generally only needs IP connectivity to the router's management interface on the local network. No valid administrator credentials are required; connecting via Wi‑Fi (e.g., guest or compromised client) or Ethernet is usually sufficient.

What is the safest general fix pattern for this type of vulnerability?

The safest pattern is to ensure all management and configuration endpoints, including setup and wizard pages, are consistently protected by strong authentication and session management. Additionally, sensitive credentials should never be returned in cleartext in UI or API responses, even to authenticated users, unless absolutely necessary and handled in a tightly controlled way.
