Synopsis

  • Ubiquiti UniFi Network Application (Controller) uses TCP 8843 for the HTTPS guest/captive portal; UniFi APs redirect guests to https://:8843/ for voucher/login on Cloud Key, Dream Machine, and server installs.
  • TP-Link Omada SDN Controller uses TCP 8843 for its HTTPS captive portal for guest Wi‑Fi authentication.
  • Some deployments expose this port publicly; attackers routinely scan for exposed UniFi/Omada controllers and have exploited web‑interface vulnerabilities in the past, so 8843 should be kept internal and systems patched.
