Is this vulnerability remotely exploitable over the internet?

It can be, depending on how the device is deployed. If the web management interface is exposed via port forwarding, remote management, or is reachable from untrusted networks, an external attacker may exploit it. If access is limited to a local network, an attacker must first gain local network access.

Does an attacker need valid credentials to exploit this issue?

No. The core problem is that restricted endpoints do not consistently verify authentication status. An attacker who can reach the management interface can attempt to access administrative URLs directly without valid credentials.

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

The safest approach is to require centralized, server-side authentication and authorization checks for all administrative endpoints. Every management request should be validated for a legitimate, active session and appropriate permissions before any configuration data is returned or modified.
