CVE-2025-67652
AutomationDirect CLICK Programmable Logic Controller Weak Encoding for Password
- Published
- Updated
- Reserved
- Assigned by
- icscert
Description
An attacker with access to the project file could use the exposed credentials to impersonate users, escalate privileges, or gain unauthorized access to systems and services. The absence of robust encryption or secure handling mechanisms increases the likelihood of this type of exploitation, leaving sensitive information more vulnerable.

What to do
Solution: AutomationDirect recommends that users update CLICK PLUS and firmware to V3.90.
Workaround: If the update cannot be applied right away, the following compensating controls are recommended until the upgrade can be performed: * Network Isolation – Disconnect the CLICK PLUS PLC from external networks (e.g., the internet or corporate LAN) to reduce exposure. * Secure Communications – Use only trusted, dedicated internal networks or air-gapped systems for device communication. * Access Control – Restrict both physical and logical access to authorized personnel only. * Application Whitelisting – Configure whitelisting so that only trusted, pre-approved applications are allowed to run. Block any unauthorized software. * Endpoint Protection – Use antivirus or EDR tools and configure host-based firewalls to block unauthorized access attempts. * Logging & Monitoring – Enable and regularly review system logs to detect suspicious or unauthorized activity. * Backup & Recovery – Maintain secure, tested backups of the PLC and its configurations to minimize downtime in case of an incident. * Ongoing Risk Assessment – Continuously evaluate risks associated with running outdated firmware and adjust compensating measures accordingly.
