This vulnerability exists in SyroTech SY-GPON-1110-WDONT Router due to storing of default username and password credentials in plaintext within the router's firmware/ database. An attacker with physical access could exploit this by extracting the firmware and reverse engineer the binary data to access the plaintext default credentials on the vulnerable system. Successful exploitation of this vulnerability could allow the attacker to gain unauthorized access to the targeted system.

This vulnerability exists in SyroTech SY-GPON-1110-WDONT Router due to storing of FTP credentials in plaintext within the SquashFS-root filesystem associated with the router's firmware. An attacker with physical access could exploit this by extracting the firmware and reverse engineer the binary data to access the plaintext FTP credentials from the vulnerable system. Successful exploitation of this vulnerability could allow the attacker to gain unauthorized access to the FTP server associated with the targeted system.

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.

An unauthorized user is able to gain access to sensitive data, including credentials, by physically retrieving the hard disk of the product as the data is stored in clear text.
