CVE-2013-4783
HighSummary
Dell iDRAC6 z firmware 1.x przed 1.92 oraz 2.x i 3.x przed 3.42, a także iDRAC7 z firmware przed 1.23.23, pozwala zdalnym atakującym na ominięcie uwierzytelnienia i wykonanie dowolnych poleceń IPMI, wykorzystując zestaw szyfrów 0 (znany jako cipher zero) oraz dowolne hasło.
Risk Assessment
Atakujący mogą uzyskać nieautoryzowany dostęp do systemu zarządzania, co może prowadzić do poważnych naruszeń bezpieczeństwa i utraty kontroli nad urządzeniami. Istnieje ryzyko, że atakujący będą mogli manipulować ustawieniami sprzętu lub uzyskać dostęp do wrażliwych danych.
Recommendation
Zaleca się aktualizację firmware'u iDRAC do najnowszej wersji, aby usunąć tę podatność. Dodatkowo, należy umieścić urządzenia DRAC w odseparowanej sieci zarządzania, aby zminimalizować ryzyko ataków z Internetu.

Original NVD description (English source)
The Dell iDRAC6 with firmware 1.x before 1.92 and 2.x and 3.x before 3.42, and iDRAC7 with firmware before 1.23.23, allows remote attackers to bypass authentication and execute arbitrary IPMI commands by using cipher suite 0 (aka cipher zero) and an arbitrary password. NOTE: the vendor disputes the significance of this issue, stating "DRAC's are intended to be on a separate management network; they are not designed nor intended to be placed on or connected to the Internet."
