CVE-2026-73174

Sensitive metadata disclosure via cleartext management traffic

Published Sep 16, 2026 · Updated Sep 16, 2026

Cleartext transmission in Advantech EKI-1242EIMS and EKI-1242IEIMS 1.06.01 and earlier allows attackers to read management metadata. The edgserver management protocol sends sensitive device identity and network metadata without transport encryption. A network-adjacent attacker must observe management traffic; the demonstrated consequence is metadata disclosure, not device modification or service interruption.
