02 Description

AutomationDirect DirectLOGIC with Ethernet Communication Uncontrolled Resource Consumption

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

1.03% probability of exploitation activity in the next 30 days.

EPSS percentile

Equal to or higher than the score of 63.5% of scored records. A rank, not a probability.

NVD base score

7.5 (CVSS v3.x), scored by the NVD independently of the CNA.

NVD analysis status

Modified. NVD last modified this record on 2026-06-17.

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 users upgrade to firmware Version 2.72 or later for all DL06 CPUs for CVE-2022-2002. Additional brute force mitigation for password access has also been added. Three incorrect password entries will result in a three hour lock out of password entry. Power cycle will allow subsequent password attempts. Please see the security network practices below for CVE-2022-2004. While automation networks and systems have built-in password protection schemes, this is only one step in securing the affected systems. Automation control system networks must incorporate data protection and security measures at least as robust as a typical business computer system. AutomationDirect recommends users of PLCs, HMI products, and other SCADA system products perform independent network security analysis to determine the proper level of security required for the application. AutomationDirect has identified the specific mitigation actions listed below: Secure physical access. Isolate and air gap networks when possible. Consider some of the AutomationDirect newer PLC families.
