Fixes

Solution

AutomationDirect recommends users upgrade to firmware Version 2.72 or later for all DL06 CPUs for CVE-2022-2002. Additional brute force mitigation for password access has also been added. Three incorrect password entries will result in a three hour lock out of password entry. Power cycle will allow subsequent password attempts. Please see the security network practices below for 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. AutomationDirect has identified the specific mitigation actions listed below: Secure physical access. Isolate and air gap networks when possible. Consider some of the AutomationDirect newer PLC families.
