CVE-2025-58069 — AutomationDirect CLICK PLUS Use of Hard-coded Cryptographic Key

The use of a hard-coded cryptographic key was discovered in firmware version 3.60 of the Click Plus PLC. The vulnerability relies on the fact that the software contains a hard-coded AES key used to protect the initial messages of a new KOPS session.

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.
How the score was calculated
  • EPSS 0.3% (30-day exploitation probability)+3
  • Technical severity (medium)+3
  • Automatable exploitation (SSVC)+3

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Remediation

Fixes and mitigations documented by the sources — linked to the original advisory.

No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

  1. Identify exposed assets running the affected vendor/product/version combinations (AutomationDirect CLICK PLUS C0-0x CPU firmware, AutomationDirect CLICK PLUS C0-1x CPU firmware, AutomationDirect CLICK PLUS C2-x CPU firmware).
  2. The attack is network-based and needs no privileges: restrict exposure (ACLs, VPN, WAF) until patched.
  3. No fix documented in the sources: reduce exposure and monitor the vendor advisory.
  4. Search available logs for exploit probes, errors and authentication anomalies.

Affected scope

Vendor, product and versions as the sources word them.

What should defenders know first?

CVE-2025-58069 is "AutomationDirect CLICK PLUS Use of Hard-coded Cryptographic Key", rated Medium. It affects CLICK PLUS C0-0x CPU firmware (AutomationDirect); versions are in the scope table. It is not in CISA KEV, which does not rule out exploitation. CVSS 5.3 describes technical severity. EPSS 0.26% estimates the probability of exploitation in 30 days; neither replaces your asset context. First verify whether exposed or business-critical assets run the affected versions, apply vendor fixes or mitigations, and preserve logs for review.
