Does this matter?

Lower severity and a low EPSS score (0.13%). Track it; it rarely justifies an emergency change on its own.

Description

This vulnerability exists in ZKTeco WL20 due to storage of Wi-Fi credentials, configuration data and system data in plaintext within the device firmware. An attacker with physical access could exploit this vulnerability by extracting the firmware and reverse engineer the binary data to access the plaintext sensitive data stored in the targeted device. Successful exploitation of this vulnerability could allow the attacker to gain unauthorized network access, retrieve and manipulate data on the targeted device.
