Is this vulnerability remotely exploitable?

Yes. As described, attackers can exploit the flaw remotely by sending crafted requests to the /register.php endpoint, provided it is reachable over the network.

Does this require authentication or an existing account?

Typically no. Registration endpoints are often publicly accessible, so an attacker usually does not need an existing account to attempt exploitation of the Username parameter.

What is the safest general fix pattern for this issue?

The most robust fix is to replace all dynamically constructed SQL that uses Username with parameterized queries or prepared statements, combined with strict input validation and least-privilege database accounts.
