CVE-2026-21643
CriticalCVSS 9.8KEVSummary
W Fortinet FortiClientEMS w wersji 7.4.4 występuje podatność na wstrzykiwanie SQL z powodu niewłaściwego neutralizowania specjalnych elementów używanych w poleceniach SQL. Atakujący, który nie jest uwierzytelniony, może wykonać nieautoryzowany kod lub polecenia za pomocą specjalnie przygotowanych żądań HTTP.
Risk Assessment
Podatność ta stwarza ryzyko dla organizacji, umożliwiając atakującym zdalne wykonanie kodu, co może prowadzić do utraty danych lub przejęcia kontroli nad systemem. Niezabezpieczone aplikacje mogą stać się celem ataków, co zagraża integralności i poufności informacji.
Recommendation
Zaleca się aktualizację Fortinet FortiClientEMS do najnowszej wersji, aby usunąć tę podatność. Dodatkowo, warto wdrożyć mechanizmy zabezpieczające, takie jak filtrowanie wejścia i monitorowanie ruchu sieciowego.
