CVE-2023-4489
Silicon Labs Z/IP Gateway Predictable S0 Encryption Key Generation Vulnerability
Description
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.
