Three incorrect password entries will result in a three hour lock out of password entry. Power cycle will allow subsequent password attempts.\n\nPlease see the security network practices below for CVE-2022-2004.\nWhile 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.\n\nAutomationDirect has identified the specific mitigation actions listed below:\n\nSecure physical access.\nIsolate and air gap networks when possible.\nConsider some of the AutomationDirect newer PLC families."

Three incorrect password entries will result in a three hour lock out of password entry. Power cycle will allow subsequent password attempts.\n\nPlease see the security network practices below for CVE-2022-2004.\nWhile 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.\n\nAutomationDirect has identified the specific mitigation actions listed below:\n\nSecure physical access.\nIsolate and air gap networks when possible.\nConsider some of the AutomationDirect newer PLC families."

Detection rules are retrieved from Rulezet.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
