Is this vulnerability remotely exploitable?

It can be, if the PDF import functionality is exposed over a network interface or integrated into a service that accepts files from remote users or systems. When file submission is remote, the arbitrary file overwrite capability effectively becomes remotely triggerable.

What level of access does an attacker need?

The attacker needs the ability to influence or provide files to the scanner's import process. This may be via a user account, an integration endpoint, or any workflow that feeds documents into the scanner, but does not typically require direct filesystem or OS-level access.

What is the safest general fix pattern?

The safest pattern is to fully decouple user-controlled input from filesystem paths: restrict all writes to a pre-defined storage directory, generate server-side file names, normalize and validate paths, and ensure the scanner process lacks permissions to write to application binaries, libraries, or system directories.
