Is this vulnerability remotely exploitable?

Yes. The vulnerable AJAX endpoint is reachable over the network, and an attacker can send crafted HTTP requests containing malicious ID parameter values without needing local access to the server.

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

An attacker generally needs only the ability to interact with the web interface or directly invoke /ajax.php?action=save_customer over HTTP/S. No prior authentication is explicitly required by the description, though real-world deployments might place this endpoint behind a login.

What is the safest general fix pattern for this vulnerability class?

The most robust fix is to refactor all affected queries to use prepared statements or parameterized queries, ensuring that user input is always bound as typed parameters rather than concatenated into SQL strings. This should be accompanied by input validation and constrained database privileges.
