Is this vulnerability remotely exploitable over the internet?

Yes, if the OpenEMR instance is exposed over the network and an attacker can obtain valid application credentials, they can potentially exploit the vulnerability remotely via the web interface.

Does exploitation require administrative access?

Not necessarily. Exploitation requires an authenticated user with access to the relevant EtherFax or document disposal functionality; this may or may not be an administrative role depending on how permissions are configured.

What is the safest general fix pattern for this issue?

The safest pattern is to completely remove user control over filesystem paths by using server-side mappings and fixed directories, combined with path canonicalization checks and operating system-level restrictions that prevent writing to executable or sensitive locations.
