CVE-2018-7798
HighSummary
W urządzeniach Modicon M221, we wszystkich wersjach, występuje podatność związana z niewystarczającą weryfikacją autentyczności danych (CWE-345). Może to prowadzić do zmiany konfiguracji IPv4 (adres IP, maska i brama) podczas zdalnego połączenia z urządzeniem.
Risk Assessment
Podatność ta może umożliwić atakującym zdalną zmianę krytycznych ustawień sieciowych, co może prowadzić do utraty kontroli nad urządzeniem oraz potencjalnych przerw w działaniu systemu.
Recommendation
Zaleca się wdrożenie dodatkowych mechanizmów weryfikacji autentyczności danych oraz monitorowanie zdalnych połączeń z urządzeniem, aby zminimalizować ryzyko nieautoryzowanych zmian.
