CVE-2021-47960
MediumSummary
W podatności CVE-2021-47960 w kliencie Synology SSL VPN przed wersją 1.4.5-0684, zewnętrzni napastnicy mogą uzyskać dostęp do plików w katalogu instalacyjnym poprzez lokalny serwer HTTP związany z interfejsem loopback. Wykorzystując interakcję użytkownika z przygotowaną stroną internetową, napastnicy mogą uzyskać wrażliwe pliki, takie jak pliki konfiguracyjne, certyfikaty i logi.
Risk Assessment
Ta podatność może prowadzić do ujawnienia poufnych informacji, co stwarza poważne ryzyko dla bezpieczeństwa danych organizacji. Ujawnienie takich plików może umożliwić atakującym dalsze działania w sieci wewnętrznej.
Recommendation
Zaleca się aktualizację klienta Synology SSL VPN do najnowszej wersji, aby usunąć tę podatność. Dodatkowo, warto ograniczyć dostęp do lokalnych serwerów HTTP oraz monitorować interakcje użytkowników z zewnętrznymi stronami internetowymi.
