Vendor Solution
AutomationDirect recommends that users update C-MORE EA9 HMI software and firmware to V6.80 https://support.automationdirect.com/firmware/historydetail.php .
Vendor Workaround
If an immediate update is not feasible, AutomationDirect recommends considering the following interim steps until the programming software can be updated: * Isolate the HMI Workstation: Disconnect the HMI from external networks (e.g., internet or corporate LAN) to limit exposure to external threats. * Use dedicated, secure internal networks or air-gapped systems for communication with programmable devices. * Control Access: Restrict physical and logical access to the HMI to authorized personnel only. * Implement Whitelisting: Use application whitelisting to allow only pre-approved and trusted software to execute on the HMI. Block untrusted or unauthorized applications. * Apply Endpoint Security Measures: Use antivirus or endpoint detection and response (EDR) tools to monitor for and mitigate threats. Ensure that host-based firewalls are properly configured to block unauthorized access. * Monitor and Log Activity: Enable logging and monitoring of system activities to detect potential anomalies or unauthorized actions. Regularly review logs for suspicious activity. * Use Secure Backup and Recovery: Regularly back up the workstation and its configurations to a secure location. Test recovery procedures to ensure minimal downtime in the event of an incident. * Conduct Regular Risk Assessments: Continuously assess the risks posed by the outdated software and adjust mitigation measures as necessary.
