Is this vulnerability remotely exploitable?

It can be, if the device's FTP service is reachable from untrusted networks such as a corporate LAN with broad access, a VPN, or the public internet. If access is tightly segmented and restricted, the practical exploitability is reduced.

What level of access does an attacker need?

An attacker needs network connectivity to the device's FTP port. No prior credentials or local physical access are required if the hardcoded password is known and the service is exposed.

What is the safest general fix pattern?

The most robust pattern is to eliminate reliance on hardcoded credentials entirely, moving to per-device, changeable credentials or stronger authentication mechanisms, and to disable non-essential services like FTP when not strictly needed.
