Overview
CVE-2026-73177 is a known-severity vulnerability. It was published on September 16, 2026.
Technical description
Nozomi Networks Labs identified a CWE-345: Insufficient Verification of Data Authenticity vulnerability in the firmware upgrade mechanism of the Advantech EKI-1242EIMS in firmware version V1.06.01. The device accepts firmware images through the authenticated web management interface without performing any cryptographic signature or certificate verification. An authenticated administrator-level attacker can install arbitrary modified firmware on the device, enabling full persistent compromise of the platform.
