Technical Details

what runs on :5672

AMQP deployments commonly use TCP, although the IANA assignment also lists UDP and SCTP. AMQP 0-9-1 begins with an AMQP protocol header followed by a connection negotiation and framed channels, methods, content headers, and message bodies; AMQP 1.0 uses its own framed connection, session, link, and transfer model. Port 5672 is the conventional unencrypted AMQP listener, while 5671 is commonly used for AMQP over TLS.

security overview

An internet-exposed broker can be targeted for password guessing, unauthorized message publication or consumption, and exploitation of broker-specific vulnerabilities. Non-TLS AMQP can expose credentials and message contents in transit, so this port should normally be restricted to trusted networks or protected with TLS, strong authentication, and authorization.

usage: This is the standard cleartext listener for AMQP message brokers such as RabbitMQ, where applications publish and consume queued messages. Engineers commonly encounter it between application services and brokers; TLS-enabled deployments conventionally use port 5671 instead.
