Last modified

CVE-2024-58311 is a high-severity vulnerability rated 8.7/10 on the CVSS scale. 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.. EPSS estimates a 0.37% chance of exploitation in the next 30 days.
