02 Description

AutomationDirect CLICK PLUS Use of Hard-coded Cryptographic Key

03 Exploitation and scoring

Exploitation
Assessed, none found. CISA's assessment recorded neither public exploit code nor evidence of exploitation when it was made.
SSVC decision
  • ExploitationnoneCISA recorded no public exploit code and no evidence of exploitation.
  • AutomatableyesAn attacker can reliably automate reconnaissance through exploitation, so this scales.
  • Technical ImpactpartialSuccessful exploitation gives limited control of the vulnerable component.
CISA publishes the decision points, not a final SSVC decision. The decision also depends on mission and well-being impact, which is a property of your deployment rather than of the vulnerability.
EPSS probability
0.26% probability of exploitation activity in the next 30 days.
EPSS percentile
Equal to or higher than the score of 17.7% of scored records. A rank, not a probability.
NVD base score
6.9 (CVSS v4.0), scored by the NVD independently of the CNA.

NVD analysis status
Deferred. NVD last modified this record on 2026-10-18.
Red Hat severity
No Red Hat rating. Red Hat rates the CVEs that affect its products.

Exploit-prediction scores from FIRST. Independent scoring and analysis status from the NVD. Vendor severity from Red Hat. Exploitation assessment and catalog membership from CISA.

07 Remediation

AutomationDirect recommends that users update CLICK PLUS and firmware to V3.80. https://www.automationdirect.com/support/software-downloads 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.
