VAR-202101-0328

Vulnerability from variot - Updated: 2023-12-18 13:18

The Eclipse Hono AMQP and MQTT protocol adapters do not check whether an authenticated gateway device is authorized to receive command & control messages when it has subscribed only to commands for a specific device. The missing check involves verifying that the command target device is configured giving permission for the gateway device to act on its behalf. This means an authenticated device of a certain tenant, notably also a non-gateway device acting like a gateway, may receive command & control messages targeted at a different device of the same tenant without corresponding permissions getting checked. Eclipse Hono Is vulnerable to a lack of authentication.Information is obtained, information is tampered with, and service is disrupted (DoS) It may be put into a state. Eclipse Hono is a software of the Eclipse Foundation for providing a control interface for connected IOT devices. The software connects a large number of IOT devices and provides a unified access interface for external control
