CVE-2008-4404
HighSummary
Implementacja protokołu odkrywania sąsiadów IPv6 (NDP) na serwerach IBM zSeries nie weryfikuje pochodzenia wiadomości odkrywania sąsiadów, co pozwala zdalnym atakującym na spowodowanie odmowy usługi (utrata łączności) lub odczytanie prywatnego ruchu sieciowego za pomocą sfałszowanej wiadomości, która modyfikuje bazę informacji o trasach (FIB).
Risk Assessment
Atakujący mogą wykorzystać tę podatność do zakłócenia działania sieci lub przechwytywania poufnych danych, co może prowadzić do poważnych konsekwencji dla bezpieczeństwa organizacji.
Recommendation
Zaleca się aktualizację oprogramowania serwera oraz wdrożenie mechanizmów weryfikacji wiadomości NDP, aby zminimalizować ryzyko związane z tą podatnością.

Original NVD description (English source)
The IPv6 Neighbor Discovery Protocol (NDP) implementation on IBM zSeries servers does not validate the origin of Neighbor Discovery messages, which allows remote attackers to cause a denial of service (loss of connectivity) or read private network traffic via a spoofed message that modifies the Forward Information Base (FIB), a related issue to CVE-2008-2476.
