Zmm220 Default Telnet Password Updated ((new)) -
Leaving these default passwords active is considered a significant security risk. Researchers have demonstrated that access via these default credentials can allow for or unauthorized data backups. It is highly recommended to disable the Telnet service entirely or update the internal configuration to use a unique, strong password if the device allows.
These devices are known to store credentials in a plain-text configuration file named ZKConfig.cfg within a tar archive that can often be downloaded via the web interface. It is highly recommended to change these default passwords and disable Telnet if it is not required for your operations, as it is an unencrypted protocol.
systemctl disable telnetd systemctl stop telnetd
