EG4 Electronics EG4 Inverters Cleartext Transmission of Sensitive Information

The MOD3 command traffic between the monitoring application and the
inverter is transmitted in plaintext without encryption or obfuscation.
This vulnerability may allow an attacker with access to a local network
to intercept, manipulate, replay, or forge critical data, including
read/write operations for voltage, current, and power configuration,
operational status, alarms, telemetry, system reset, or inverter control
commands, potentially disrupting power generation or reconfiguring
inverter settings.
