CVE-2012-3039
HighSummary
Urządzenia Moxa OnCell Gateway G3111, G3151, G3211 i G3251 z firmware przed wersją 1.4 nie wykorzystują wystarczającego źródła entropii do generowania kluczy SSH i SSL. To ułatwia zdalnym atakującym uzyskanie dostępu, wykorzystując wiedzę o kluczu z innej instalacji produktu.
Risk Assessment
Organizacja narażona jest na ryzyko nieautoryzowanego dostępu do urządzeń, co może prowadzić do poważnych incydentów bezpieczeństwa. Atakujący mogą wykorzystać znane klucze do przejęcia kontroli nad systemem.
Recommendation
Zaleca się aktualizację firmware urządzeń do wersji 1.4 lub nowszej, aby poprawić bezpieczeństwo generowania kluczy SSH i SSL. Dodatkowo, warto rozważyć zmianę kluczy na nowe, aby zminimalizować ryzyko związane z istniejącymi kluczami.

A vulnerability in the ash_authentication library (Elixir) allows an attacker who can plant a remember-me cookie in a victim's browser to replace the victim's authenticated session with one for the attacker's own account. The issue stems from a mismatch between the session keys used by the guard and the reader, causing remember-me sign-in to run on every request.
Original NVD description (English source)
Moxa OnCell Gateway G3111, G3151, G3211, and G3251 devices with firmware before 1.4 do not use a sufficient source of entropy for SSH and SSL keys, which makes it easier for remote attackers to obtain access by leveraging knowledge of a key from a product installation elsewhere.
