GHSA-6JW3-XMJ9-QVCW

Vulnerability from github – Published: 2023-12-15 00:31 – Updated: 2023-12-15 00:31

Details

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.

Severity ?

6.4 (Medium)


                  
                    CVSS:3.1/AV:P/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H
