CVE-2023-4489
Last modified
CVE-2023-4489 is a critical-severity vulnerability rated 9.8/10 on the CVSS scale. 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.. EPSS estimates a 0.53% chance of exploitation in the next 30 days.
