Technical Details

what runs on :7648

CU-SeeMe was a legacy Internet video-conferencing application associated with traffic on port 7648. IANA lists both TCP and UDP for the bonjour-cuseeme assignment, but that does not establish a single, broadly standardized wire protocol or imply that a current listener will be present. Treat an open port as application-specific and verify the process and traffic rather than assuming it is a modern Bonjour service.

security overview

This is a legacy, uncommon service rather than a port expected on a typical current internet host. If a CU-SeeMe-era application is listening, do not assume its media or signaling is encrypted; restrict access to trusted networks and investigate unexpected exposure. There is no basis here to attribute a specific vulnerability to every listener on this port.
