CVE-2012-0352
HighSummary
Podatność w systemie Cisco NX-OS przed wersją 4.2(1)SV1(5.1) na przełącznikach serii Nexus 1000v oraz przed wersją 5.0(2)N1(1) na przełącznikach serii Nexus 5000, a także przed wersjami 4.2.8, 5.0.5 i 5.1.1 na przełącznikach serii Nexus 7000, pozwala zdalnym atakującym na wywołanie odmowy usługi poprzez wadliwy pakiet IP, co prowadzi do awarii procesu netstack i ponownego uruchomienia urządzenia.
Risk Assessment
Atakujący mogą wykorzystać tę podatność do zakłócenia działania sieci, co może prowadzić do przestojów w usługach i utraty dostępności krytycznych zasobów.
Recommendation
Zaleca się aktualizację systemu NX-OS do najnowszej wersji, aby usunąć tę podatność oraz monitorowanie ruchu sieciowego w celu wykrywania potencjalnych ataków.
