CVE-2018-17924
HighCVSS 8.6Summary
Kontrolery Rockwell Automation MicroLogix 1400 oraz moduły komunikacyjne 1756 ControlLogix są podatne na atak zdalny, który pozwala nieautoryzowanemu podmiotowi wysłać żądanie połączenia CIP. Po nawiązaniu połączenia, atakujący może zmienić konfigurację IP urządzenia, co prowadzi do utraty komunikacji z systemem.
Risk Assessment
Organizacja narażona jest na poważne zakłócenia w komunikacji systemowej, co może prowadzić do awarii operacyjnych i utraty kontroli nad urządzeniami. Tego rodzaju atak może również wpłynąć na bezpieczeństwo całego systemu.
Recommendation
Zaleca się wdrożenie odpowiednich środków zabezpieczających, takich jak ograniczenie dostępu do urządzeń oraz monitorowanie ruchu sieciowego, aby zminimalizować ryzyko nieautoryzowanych zmian konfiguracji.

Original NVD description (English source)
Rockwell Automation MicroLogix 1400 Controllers and 1756 ControlLogix Communications Modules An unauthenticated, remote threat actor could send a CIP connection request to an affected device, and upon successful connection, send a new IP configuration to the affected device even if the controller in the system is set to Hard RUN mode. When the affected device accepts this new IP configuration, a loss of communication occurs between the device and the rest of the system as the system traffic is still attempting to communicate with the device via the overwritten IP address.
