CVE-2024-58311
📋 TL;DR
The Dormakaba Saflok System 6000 uses a predictable key generation algorithm that allows attackers to derive valid card access keys from a 32-bit unique identifier. This enables unauthorized physical access to secured areas by creating cloned access cards. Organizations using this physical access control system are affected.

⚠️ Risk & Real-World Impact
Worst Case
Complete physical security compromise allowing attackers unrestricted access to all secured areas controlled by the system, potentially enabling theft, sabotage, or unauthorized entry to sensitive locations.
Likely Case
Attackers create cloned access cards to gain unauthorized entry to buildings, rooms, or secured areas, potentially leading to theft, espionage, or safety breaches.
If Mitigated
With proper monitoring and layered security controls, unauthorized access attempts can be detected and responded to before significant damage occurs.
🎯 Exploit Status
Exploitation requires physical proximity to read card identifiers, but the key derivation itself is simple mathematical transformation.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not applicable - requires hardware/firmware replacement
Vendor Advisory: https://www.dormakaba.com/
Restart Required: No
Instructions:
Contact Dormakaba for hardware replacement or firmware upgrade options. This vulnerability requires replacing the cryptographic algorithm implementation.
🔧 Temporary Workarounds
Enhanced Physical Monitoring
allIncrease physical security monitoring and implement additional access control layers
Card Rotation Policy
allImplement frequent card replacement to limit window of opportunity for cloned cards
🧯 If You Can't Patch
- Implement multi-factor authentication for sensitive areas (biometrics, PIN codes)
- Deploy security personnel or surveillance systems to monitor access points
