TCP 8500
Synopsis
- HashiCorp Consul uses TCP 8500 by default for its HTTP API and web UI (e.g., http://localhost:8500) in service-discovery deployments.
- Adobe ColdFusion’s built-in development web server (Jetty/cfusion) listens on TCP 8500 by default, serving apps and the ColdFusion Administrator during local installs.
- Flight Message Transfer Protocol (FMTP) is IANA-registered on TCP 8500 and is used in European air-traffic control networks (e.g., EUROCONTROL-compliant ANSP systems) for flight message exchange.
- Security note: Attackers commonly scan port 8500 for exposed Consul APIs (to register malicious services or abuse health checks for code execution) and for vulnerable ColdFusion instances to achieve remote code execution.
