Is this vulnerability remotely exploitable over the internet?

Yes. If the Customer Support System's `ajax.php` endpoint is exposed to the internet, an attacker anywhere online can send crafted requests to invoke administrative actions without logging in.

Does an attacker need a valid user account to exploit this issue?

No. The issue arises because the dispatcher does not enforce authentication or authorization, so no user account or valid session is required—only network access to the vulnerable endpoint.

What is the safest general fix pattern for this kind of bug?

Introduce a centralized access control layer ensuring that all requests to `ajax.php` (and similar endpoints) are authenticated and that the caller's role is checked against the required privileges before any administrative or state-changing action is executed.
