CVE-2024-25138Network attack vector

Credential disclosure via plaintext on-device storage

Published Mar 26, 2024 · Updated Aug 2, 2024

Plaintext credential storage in AutomationDirect C-MORE EA9 HMI 6.77 and earlier allows remote authenticated users to read credentials. The platform writes credentials to device storage without encryption; public advisories identify neither the storage locus nor the retrieval interface. Network access with low privileges is required, and the reported consequence is limited to credential disclosure without data modification or service interruption.
