TCP 18083
Synopsis
- EMQX (formerly EMQ) MQTT broker uses TCP port 18083 by default for its HTTP-based Dashboard and REST management API.
- Real-world examples include EMQX 4.x/5.x installations and the official emqx/emqx Docker image, which expose the admin UI on http://host:18083.
- Security: Attackers commonly scan for exposed EMQX dashboards on 18083; instances left with default credentials or weak authentication have been taken over to control MQTT topics and clients.
