Technical Details

what runs on :7675

The assignment refers to the Message Queue tunnel component, which carries Message Queue client traffic through an HTTP-based tunnel rather than acting as a general-purpose HTTP service. It was intended for deployments where direct broker connections were blocked by firewalls; HTTPS could be used for a protected tunnel, but encryption should not be assumed by port number alone. IANA lists both TCP and UDP for 7675, though the documented tunneling use is TCP/HTTP-based; do not infer that a UDP listener is present. The ordinary Message Queue broker listener is a separate service, commonly on TCP 7676.

security overview

This is a legacy, uncommon middleware endpoint, so an unexpected listener warrants identifying the process and verifying that it is actually a Message Queue tunnel. If enabled, restrict it to required clients and use an encrypted tunnel configuration; exposing an old broker-facing component publicly can reveal or enable access to messaging services, depending on its authentication and configuration.

Record

iana registry entry

port: :7675
service: Sun Java System Message Queue Tunnel
transport: TCPUDP
encryption: cleartext
assignment: iana registered
risk: 2/10safe
category: Network Services
usage: This is associated with the HTTP tunneling support in Sun Java System Message Queue (iMQ), later known as Oracle GlassFish/Open Message Queue. Engineers are most likely to encounter it in older deployments that used tunneling to let messaging clients reach a broker across restrictive firewalls; it is uncommon today.
