Descriptions

In Mosquitto before 1.4.12, pattern based ACLs can be bypassed by clients that set their username/client id to '#' or '+'. This allows locally or remotely connected clients to access MQTT topics that they do have the rights to. The same issue may be present in third party authentication/access control plugins for Mosquitto.

En Mosquitto en versiones anteriores a la 1.4.12, las listas de control de acceso (ACL) basadas en patrones pueden ser omitidas por clientes que establecen su ID de nombre de usuario/cliente como '#' o '+'. Esto permite que los clientes conectados de forma local o remota accedan a temas MQTT a los que no tienen derecho de acceso. Este mismo problema también podría estar presente en plugins de control de autenticación/acceso para Mosquitto.
