HMS Networks Ewon Flexy 202

An attacker with network access to an Ewon Flexy 202 device could intercept and steal user credentials, potentially gaining access to remote management capabilities and sensitive plant data. Compromised credentials could enable unauthorized remote access to industrial control systems and process networks.

Water authorities, electric utilities, and other industrial facilities using HMS Networks Ewon Flexy 202 remote access gateways for secure connectivity to PLCs, RTUs, HMIs, and other control systems. The Ewon Flexy 202 is commonly deployed at the boundary between corporate and industrial networks to enable remote engineering access and diagnostics.

An attacker positioned on the same network segment as the Ewon Flexy 202 (or on the path between the device and its management interface) can perform packet capture or man-in-the-middle techniques to intercept network traffic. If the device transmits credentials in cleartext, the attacker can extract valid user credentials from the captured traffic and use them to gain unauthorized access to the device or connected systems.
