Threat database

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.

EPSS 0.1%VulnerabilityZKTeco Co#cwe-312Germany+9

This vulnerability exists in ZKTeco WL20 due to hard-coded private key stored in plaintext within the device firmware. An attacker with physical access could exploit this vulnerability by extracting the firmware and analyzing the binary data to retrieve private key stored in the firmware of the targeted device. Successful exploitation of this vulnerability could allow the attacker to perform unauthorized decryption of sensitive data and Man-in-the-Middle (MitM) attacks on the targeted device.

EPSS 0.2%VulnerabilityZKTeco Co#cwe-798Germany+9

This vulnerability exists in ZKTeco WL20 due to hard-coded MQTT credentials and endpoints stored in plaintext within the device firmware. An attacker with physical access could exploit this vulnerability by extracting the firmware and analyzing the binary data to retrieve the hard-coded MQTT credentials and endpoints from the targeted device. Successful exploitation of this vulnerability could allow the attacker to gain unauthorized access to the MQTT broker and manipulate the communications of the targeted device.

EPSS 0.2%VulnerabilityZKTeco Co#cwe-798Germany+9

This vulnerability exists in ZKTeco WL20 due to storage of admin and user credentials without encryption in 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 unencrypted credentials stored in the firmware of targeted device.
