CVE-2023-4489

The first S0 encryption key is generated with an uninitialized PRNG in Z/IP Gateway products running Silicon Labs Z/IP Gateway SDK v7.18.3 and earlier. This makes the first S0 key generated at startup predictable, potentially allowing network key prediction and unauthorized S0 network access.

Summary		(es) La primera clave de cifrado S0 se genera con un PRNG no inicializado en productos Z/IP Gateway que ejecutan Silicon Labs Z/IP Gateway SDK v7.18.3 y versiones anteriores. Esto hace que la primera clave S0 generada al inicio sea predecible, lo que potencialmente permite la predicción de claves de red y el acceso no autorizado a la red S0.
