Summary

In Eclipse KUKSA Databroker version 0.6.1, the `kuksa.val.v2.VAL/PublishValue` gRPC handler fails to validate the existence of the optional `data_point` field in `PublishValueRequest`. When a request contains a valid `signal_id` but omits `data_point`, the server calls `unwrap()` on `request.data_point`, causing a panic in the Tokio worker thread. This issue can be triggered by any client holding a valid JWT token.

Risk Assessment

An attacker with a valid JWT token can cause a worker thread panic, resulting in cancellation of a single gRPC call. Although the Databroker process does not terminate, this can disrupt service and affect availability for other requests.

Recommendation

Update Eclipse KUKSA Databroker to a version that fixes the validation of the `data_point` field in the `PublishValue` handler. If an update is not possible, restrict access to the service to trusted clients with valid JWT tokens.

Original NVD description (English source)

In Eclipse KUKSA Databroker version 0.6.1, the kuksa.val.v2.VAL/PublishValue gRPC handler fails to validate the existence of the optional data_point field in PublishValueRequest. When a request contains a valid signal_id but omits data_point, the server directly calls unwrap() on request.data_point, triggering a panic in the Tokio worker thread. This issue can be triggered by any client holding a valid JWT token. Unauthenticated or invalid-token requests are rejected and do not reach the vulnerable path. The panic causes the individual gRPC call to be cancelled but does not terminate the Databroker process, which remains available for subsequent requests.
