Recommendation: Monitor — no exploitation signal at the moment.

The DMP-5000 file service exposes authenticated arbitrary file upload functionality. There are exposed endpoints which allows authenticated users to upload files of any type without validation. No file extension filtering or content inspection is enforced which allows executable binaries and scripts to be accepted and written directly to the server.
