The Dormakaba Saflok System 6000 is an electronic access control system widely deployed in various sectors including hospitality, corporate offices, and critical infrastructure. CVE-2024-58311 identifies a vulnerability categorized under CWE-1245 (Improper Finite State Machines in Hardware Logic), where the hardware logic responsible for generating card access keys uses a deterministic and predictable algorithm. Specifically, the system generates access keys from a 32-bit unique identifier embedded in each card. Due to the flawed finite state machine design, attackers can mathematically derive valid access keys by applying a straightforward transformation to the card's unique identifier, effectively bypassing the intended cryptographic protections. The vulnerability does not require any authentication, user interaction, or elevated privileges, and can be exploited remotely if the attacker can access the system's communication channels. The CVSS 4.0 score of 8.7 reflects the high impact on confidentiality, integrity, and availability, as unauthorized access compromises physical security and potentially allows malicious actors to enter restricted areas undetected. No patches or firmware updates have been published yet, and while no active exploits are known, the simplicity of the key derivation method suggests that exploitation could be straightforward once the vulnerability is understood. This flaw highlights the risks of hardware-based security relying on weak finite state machine implementations and predictable key generation.

For European organizations, this vulnerability poses a critical risk to physical security controls. Unauthorized derivation of access keys can lead to unauthorized entry into sensitive facilities such as data centers, government buildings, hospitals, and corporate offices. This compromises confidentiality by exposing sensitive information and assets, integrity by allowing tampering or theft, and availability by potentially disrupting operations through unauthorized physical access. The risk is amplified in sectors with high security requirements, including critical infrastructure and financial institutions. Given the widespread use of Dormakaba Saflok System 6000 across Europe, attackers could leverage this vulnerability to conduct espionage, sabotage, or theft. The lack of patches and the ease of exploitation increase the urgency for organizations to implement compensating controls. Additionally, the vulnerability could undermine trust in electronic access control systems, leading to costly security overhauls and reputational damage.

1. Immediately restrict network access to the Dormakaba Saflok System 6000 management interfaces, ensuring they are not exposed to untrusted networks or the internet. 2. Implement strict physical security controls around access control hardware to prevent attackers from obtaining card unique identifiers or intercepting communication. 3. Monitor access logs for anomalous patterns indicating potential unauthorized key derivation or use of cloned cards. 4. Employ multi-factor authentication for critical access points where possible, combining electronic access with biometric or PIN verification. 5. Engage with Dormakaba for firmware updates or patches and apply them promptly once available. 6. Conduct a thorough inventory of all deployed Saflok System 6000 devices and assess exposure levels. 7. Consider temporary use of alternative access control methods or additional physical locks until the vulnerability is remediated. 8. Train security personnel to recognize signs of physical security breaches related to this vulnerability. 9. Collaborate with industry peers and national cybersecurity centers to share threat intelligence and mitigation strategies. 10. Evaluate the feasibility of replacing vulnerable hardware with more secure alternatives in the medium term.
