CVE-2025-15128Public exploitNetwork attack vector

Credential disclosure via cleartext safe-setting response

Published Dec 28, 2025 · Updated Dec 28, 2025

Credential disclosure in ZKTeco BioTime 9.0.0 through 9.0.4 and 9.5.0 through 9.5.2 allows remote attackers to read encryption passwords. The /base/safe_setting/ endpoint renders backup_encryption_password_decrypt and export_encryption_password_decrypt values in cleartext HTML password fields. Tested 9.0.3 and 9.5.2 builds require no login, while tested 9.0.4 requires a low-privilege session; disclosure exposes backup and export credentials.
