CVE-2024-13962
HighSummary
Podatność CVE-2024-13962 dotyczy usługi TuneupSvc w programie Avast Cleanup Premium w wersji 24.2.16593.17810 na systemie Windows 10 Pro x64. Umożliwia lokalnym atakującym eskalację uprawnień i wykonanie dowolnego kodu w kontekście SYSTEM poprzez stworzenie symbolicznego linku i wykorzystanie ataku TOCTTOU (czas sprawdzenia do czasu użycia).
Risk Assessment
Zagrożenie dla organizacji polega na możliwości eskalacji uprawnień przez lokalnych atakujących, co może prowadzić do nieautoryzowanego dostępu do systemu i wykonania szkodliwego kodu. To stwarza ryzyko poważnych naruszeń bezpieczeństwa i utraty danych.
Recommendation
Zaleca się aktualizację oprogramowania Avast Cleanup do najnowszej wersji, aby usunąć tę podatność. Dodatkowo, warto monitorować i ograniczać dostęp do systemów, aby zminimalizować ryzyko lokalnych ataków.
