CVE-2023-4489: Z/IP Gateway Use of Uninitialized PRNG when Generating S0 Encryption Key
First published: Thu Dec 14 2023(Updated: )
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.
