CVE-2020-10876 Information

Description

The OKLOK (3.1.1) mobile companion app for Fingerprint Bluetooth Padlock FB50 (2.3) does not correctly implement its timeout on the four-digit verification code that is required for resetting passwords nor does it properly restrict excessive verification attempts.
