Technical Details

what runs on :4090

This assignment covers both TCP and UDP for OMA BCAST Service Guide traffic. The payload is service-guide metadata for OMA BCAST deployments, generally exchanged as part of a broadcast-service discovery and provisioning system rather than as a conventional public server protocol. Exact delivery and framing depend on the OMA BCAST profile and deployment, and the port should not be assumed to provide a generic request/response service; service-guide data may be delivered over broadcast-oriented infrastructure or a supporting IP path. OMA BCAST transport-level use does not imply encryption by default.

security overview

This is a specialized, rarely exposed service and is normally expected only within mobile-broadcast infrastructure, not on an internet-facing host. If reachable, an attacker may be able to submit malformed service-guide data or probe for implementation-specific parsing and provisioning weaknesses; restrict it to the required network and rely on the deployment's separate content-protection and authentication mechanisms.
