Is this vulnerability remotely exploitable?

Yes. If the upload endpoint is reachable over the network and the server executes certain file types from the upload directory, an attacker can typically exploit it remotely by uploading a crafted file and accessing it via HTTP.

What level of access does an attacker need?

The attacker must be able to use the Files Manager's upload functionality. In many deployments this may require a CMS account with file management permissions, but in misconfigured setups the interface could be more broadly exposed. The exact access needed depends on how authentication and roles are configured.

What is the safest general fix pattern?

The safest pattern is to strictly allow only a small set of benign file types, store all uploads in non-executable locations, and ensure that file serving is mediated by the application rather than executed directly by the web server. This should be supported by server configuration that disallows script execution in upload directories.
