Descriptions

RIOT 2019.07 contains a NULL pointer dereference in the MQTT-SN implementation (asymcute), potentially allowing an attacker to crash a network node running RIOT. This requires spoofing an MQTT server response. To do so, the attacker needs to know the MQTT MsgID of a pending MQTT protocol message and the ephemeral port used by RIOT's MQTT implementation. Additionally, the server IP address is required for spoofing the packet.

RIOT versión 2019.07, contiene una desreferencia del puntero NULL en la implementación MQTT-SN (asymcute), lo que permite potencialmente a un atacante bloquear un nodo de red que ejecuta RIOT. Esto requiere falsificar una respuesta del servidor MQTT. Para hacerlo, el atacante necesita conocer el MsgID de MQTT de un mensaje de protocolo MQTT pendiente y el puerto efímero utilizado por la implementación MQTT de RIOT. Adicionalmente, es requerida la dirección IP del servidor para suplantar el paquete.
