Description
An issue was discovered on MECO USB Memory Stick with Fingerprint MECOZiolsamDE601 devices. The fingerprint authentication requirement for data access can be bypassed. An attacker with physical access can send a static packet to a serial port exposed on the PCB to unlock the key and get access to the data without possessing the required fingerprint.
