UDP 41794
Synopsis
- UDP port 41794 is registered for Crestron-CTP (Crestron Control/Terminal Protocol), used by Crestron control systems. In real deployments, Crestron 3‑Series/4‑Series processors (e.g., CP3, CP4, AV3, PRO3, RMC3/MC4R) and TSW-series touch panels, as well as Crestron XPanel and Crestron Toolbox software, use this port for control/management communications (alongside TCP on the same port). You’ll commonly see 41794/udp open on Crestron DMPS3 series presentation systems and other Ethernet-enabled Crestron devices for remote control and programming. Security note: Internet-exposed Crestron control ports (including 41794/udp) have been found via scanning and can be abused for unauthorized control when devices are left with weak or default credentials.
