Weakness
Affected products
AutomationDirect · Productivity Suite
- affected ≤ v4.6.2.2
- unaffected v4.7.0.47
What to do
Solution: AutomationDirect recommends that users update Productivity suite to v4.7.0.47 and above https://www.automationdirect.com/support/software-downloads
Workaround: If the update cannot be applied right away, the following compensating controls are recommended until the upgrade can be performed. * Disconnect the engineering workstation from external networks (e.g., the internet or corporate LAN) to reduce exposure. * Use only trusted, dedicated internal networks or air-gapped systems for device communication. * Restrict both physical and logical access to authorized personnel only. * Configure whitelisting so that only trusted, pre-approved applications are allowed to run. Block any unauthorized software. * Use antivirus or EDR tools and configure host-based firewalls to block unauthorized access attempts. * Enable and regularly review system logs to detect suspicious or unauthorized activity. * Maintain secure, tested backups of the PLC and its configurations to minimize downtime in case of an incident. * Continuously evaluate risks associated with running outdated firmware and adjust compensating measures accordingly.
