Descriptions

The programming protocol allows for a previously entered password and lock state to be read by an attacker. If the previously entered password was successful, the attacker can then use the password to unlock Automation Direct CLICK PLC CPU Modules: C0-1x CPUs with firmware prior to v3.00.

El protocolo de programación permite que un atacante lea la contraseña introducida previamente y el estado de bloqueo. Si la contraseña introducida previamente fue satisfactoria, el atacante puede usar la contraseña para desbloquear los módulos de CPU del PLC de Automation Direct CLICK: CPUs C0-1x con versiones de firmware anteriores a v3.00
