CVE-2018-25112
HighSummary
Podatność CVE-2018-25112 pozwala nieautoryzowanemu zdalnemu atakującemu na wykorzystanie niekontrolowanego zużycia zasobów w programie IEC 61131, co prowadzi do przeciążenia urządzenia. Atakujący może generować dużą ilość ruchu sieciowego, który musi być obsłużony przez ILC.
Risk Assessment
Ryzyko dla organizacji polega na możliwości wystąpienia ataku typu Denial-of-Service, co może prowadzić do niedostępności urządzeń i zakłócenia operacji. Tego typu atak może wpłynąć na ciągłość działania systemów przemysłowych.
Recommendation
Zaleca się monitorowanie ruchu sieciowego oraz wdrożenie mechanizmów ograniczających ilość obsługiwanych połączeń, aby zminimalizować ryzyko ataku. Należy również rozważyć aktualizację oprogramowania do najnowszej wersji, jeśli to możliwe.

Original NVD description (English source)
An unauthenticated remote attacker may use an uncontrolled resource consumption in the IEC 61131 program of the affected products by creating large amounts of network traffic that needs to be handled by the ILC. This results in a Denial-of-Service of the device.
