CVE-2020-37126
CriticalSummary
Free Desktop Clock 3.0 zawiera podatność na przepełnienie stosu w polu wejściowym nazwy strefy czasowej, co pozwala atakującym na nadpisanie rejestrów Structured Exception Handler (SEH). Wykorzystując złośliwe dane wejściowe w formacie Unicode, atakujący mogą wywołać naruszenie dostępu i potencjalnie wykonać dowolny kod.
Risk Assessment
Podatność ta stwarza ryzyko wykonania złośliwego kodu, co może prowadzić do przejęcia kontroli nad systemem. Organizacje powinny być świadome możliwości wykorzystania tej luki przez atakujących.
Recommendation
Zaleca się aktualizację oprogramowania Free Desktop Clock do najnowszej wersji, aby usunąć tę podatność. Dodatkowo, warto monitorować i ograniczać dostęp do aplikacji, aby zminimalizować ryzyko ataku.
