Is this vulnerability remotely exploitable?

Yes. If the authentication endpoint is network-accessible, an attacker can exploit this vulnerability remotely by scripting large numbers of login attempts.

What level of access does an attacker need?

Only network access to the authentication interface is required; no existing account or prior authentication is necessary to generate a denial-of-service condition or attempt brute-force attacks.

What is the safest general fix pattern?

The most robust pattern is to enforce layered controls: implement server-side rate limiting and lockout or step-up verification on failed attempts, apply progressive delays for repeated failures, and complement these with strong authentication mechanisms such as MFA.
