Remediations

• CVE-2022-2004: While automation networks and systems have built-in password protection schemes, this is only one step in securing the affected systems. Automation control system networks must incorporate data protection and security measures at least as robust as a typical business computer system. AutomationDirect recommends users of PLCs, HMI products, and other SCADA system products perform independent network security analysis to determine the proper level of security required for the application.
• CVE-2022-2004: Secure physical access.
• CVE-2022-2004: Isolate and air gap networks when possible.
• CVE-2022-2004: Consider some of the AutomationDirect newer PLC families.
• CVE-2022-2004: Users can refer to the following link for supporting information related to security considerations.
• For CVE-2022-2003: Update all D0-06 series CPUs to firmware version 2.72 or later
• For CVE-2022-2003: Update all DL05 series CPUs to firmware version 5.41 or later
• For CVE-2022-2003: D2-240/250 is obsolete and cannot be upgraded. AutomationDirect recommends upgrading to a newer PLC (D2-262 or newer PLC families; CLICK, Do-more/BRX and Productivity Series).
• For CVE-2022-2003: Update D2-250-1 to firmware version 4.91 or later
