Is this vulnerability remotely exploitable over the internet?

It is exploitable through the Froxlor web interface or API but typically requires an authenticated customer account with DNS management rights. It is not generally exploitable by unauthenticated external users.

What level of access does an attacker need?

The attacker must have a customer role (or equivalent) with DNS enabled and permission to create or modify DNS records via the `DomainZones.add` endpoint. They do not need direct shell access or file-system access to the DNS server.

What is the safest general fix pattern for this issue?

The most robust fix is to implement strict, per-type validation of DNS record content and to neutralize or forbid characters that have structural meaning in BIND zone files (such as newlines and `$`-prefixed directives) before writing any user-controlled data to zone templates.
