Is this vulnerability remotely exploitable?

Yes. If the inets HTTP server is exposed over the network and has the affected ScriptAlias and directory-rule configuration, an attacker can exploit the issue remotely by sending crafted HTTP requests to CGI endpoints.

Does an attacker need valid credentials to exploit it?

No, in the vulnerable configuration the flaw specifically allows unauthenticated users to access CGI scripts that should be protected by directory-based access rules, bypassing the need for credentials.

What is the safest general fix pattern?

Ensure that authorization checks are performed against the canonical resource path used for script execution, and avoid relying on DocumentRoot-relative directory rules to protect CGI scripts that are mapped via ScriptAlias to external directories. Where possible, apply explicit per-URL or per-script authorization rules that align with the alias configuration.
