Descriptions

In version 6.5 of Microchip MiWi software and all previous versions including legacy products, there is a possibility of frame counters being validated/updated prior to the message authentication. With this vulnerability in place, an attacker may increment the incoming frame counter values by injecting messages with a sufficiently large frame counter value and invalid payload. This results in denial of service/valid packets in the network. There is also a possibility of a replay attack in the stack.

En la versión 6.5 del software Microchip MiWi y en todas las versiones anteriores, incluidos los productos heredados, existe la posibilidad de que los contadores de tramas se validen/actualicen antes de la autenticación del mensaje. Con esta vulnerabilidad, un atacante puede incrementar los valores del contador de tramas entrantes inyectando mensajes con un valor de contador de tramas suficientemente grande y una carga útil no válida. Esto da lugar a la denegación de servicio/paquetes no válidos en la red. También existe la posibilidad de un ataque de repetición en la pila
