Festo: Multiple Festo products contain an unsafe default Codesys configuration

view advisory published 2022-11-29

The products are shipped with an unsafe configuration of the integrated CODESYS Runtime environment. In this case no default password is set to the CODESYS PLC and therefore access without authentication is possible. With a successful established connection to the CODESYS Runtime the PLC-Browser commands are available. Thus granting the possibilities to e.g. read and modify the configuration file(s), start/stop the application and reboot the device.
