# WHartTest: missing authentication lets anyone hijack WebSocket test sessions

WHartTest through 2.8.1 accepts WebSocket connections on its UI endpoints without checking identity. An unauthenticated attacker can read other users' test-case payloads and step results, and inject spoofed results and screen frames into victim sessions.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed WHartTest version and confirm whether it is `2.8.1` or earlier.
- Confirm whether the `/ws/ui/web/` and `/ws/ui/actuator/` endpoints are reachable from untrusted networks.
- Look at `UiAutomationConsumer` in the WHartTest source for an authentication check on WebSocket connect.

## Fix

- Upgrade WHartTest past `2.8.1` once a fixed release is published; the sources do not name a fixed version.
- Until patched, block external access to `/ws/ui/web/` and `/ws/ui/actuator/` at the reverse proxy or firewall.

## From the sources

WHartTest through 2.8.1 contains a missing authentication vulnerability that allows unauthenticated attackers to connect to the /ws/ui/web/ and /ws/ui/actuator/ WebSocket endpoints because UiAutomationConsumer accepts every connection. Attackers can register an actuator with a client-supplied id to intercept other users' test-case payloads, receive broadcast step results, and spoof results and screen frames into victim sessions.
