Provided the fix in CVE-2020-10059 is applied, the attack requires compromise of the server. See NCC-ZEP-030 This issue affects: zephyrproject-rtos zephyr version 2.1.0 and later versions. version 2.2.0 and later versions.

En la función updatehub_probe, justo después que el análisis JSON es completado, objects\[1] es accedido desde la estructura de salida en dos lugares diferentes. Si el JSON contenía menos de dos elementos, este acceso haría referencia a la memoria de la pila no inicializada. Esto podría resultar en un bloqueo, una denegación de servicio o posiblemente un filtrado de información. Siempre que la corrección en el CVE-2020-10059 sea aplicada, el ataque requiere un compromiso del servidor. Consulte NCC-ZEP-030.
