Detection & IOCsextracted from sources · hover to see the quote
- →Authentication bypass via specially crafted URL targeting the EMG12 web interface — look for anomalous or malformed URL patterns in HTTP requests to the device's web management interface ↗
- →Credentials or session tokens may be exposed in HTTP GET query strings on the EMG12 web interface — monitor for GET requests containing authentication parameters that could be replayed for impersonation ↗
- →Target scope: Entes EMG12 Ethernet Modbus Gateway running firmware version 2.57 or prior — identify and prioritize these devices in network asset inventory for monitoring ↗
- ·No known public exploits specifically target these vulnerabilities at time of advisory publication — threat may be lower but the CVSS v3 score of 9.8 reflects unauthenticated remote exploitability ↗
- ·Both CVE-2018-14826 (auth bypass) and CVE-2018-14822 (query string info exposure) affect the same web interface on the same device — detections should account for both attack vectors simultaneously ↗
