| Vulnerability | Description | |---------------|-------------| | | Scanning a QR code containing SQL injection can validate authentication and open doors; embedding too much data causes device reboot | | Weak network protocol authentication | The proprietary protocol on TCP port 4370 uses passwords between 0–999999 (easily brute-forced); default value is zero | | Reversible authentication codes | Message authentication code (MAC) uses reversible operations, making network traffic analysis viable | | SSH credential exposure | Root and zkteco user passwords can be recovered from device memory | | Remote user data manipulation | Attackers can remotely download photos, upload new users, exclude legitimate employees, and inject Unix shell commands | | Buffer overflow exploitation | Vulnerabilities in firmware update commands allow arbitrary code execution |
