A weakness has been identified in Sipeed PicoClaw up to 0.2.9. Affected by this issue is some unknown functionality of the file pkg/channels/mqtt/mqtt.go of the component MQTT Channel Handler. This manipulation of the argument client_id causes incorrect authorization. The attack is possible to be carried out remotely. The exploit has been made available to the public and could be used for attacks. The reported GitHub issue was closed automatically due to inactivity.
