  "title": "Authentication bypass in UgCS server HCI login",
  "summary": "UgCS server versions before 6.2 are affected by an authentication bypass in the HCI login service. An unauthenticated network attacker can gain a privileged session when TCP port 3334 is reachable and the server has exactly one configured user, potentially allowing control of connected drones or changes to flight routes.",
  "mitigation": "Upgrade UgCS to version 6.2 or later. Until the upgrade is complete, restrict TCP port 3334 to trusted management networks and prevent untrusted hosts from reaching it.",
