Summary

WHartTest through 2.8.1 from MGdaasLab contains missing authentication on the /ws/ui/web/ and /ws/ui/actuator/ WebSocket endpoints, because UiAutomationConsumer accepts every connection. An unauthenticated remote attacker can connect to these endpoints and register an actuator with a client-supplied id to intercept other users' test-case payloads. The attacker can also receive broadcast step results and spoof results and screen frames into victim sessions, as CWE-306 describes.
