CVE-2024-58311 | Dormakaba Saflok System 6000 contains a predictable key gene… | CVSS 9.8 CRITICAL

Description

Dormakaba Saflok System 6000 contains a predictable key generation algorithm that allows attackers to derive card access keys from a 32-bit unique identifier. Attackers can exploit the deterministic key generation process by calculating valid access keys using a simple mathematical transformation of the card's unique identifier.
