CVE-2008-3809
HighSummary
Cisco IOS w wersjach od 12.0 do 12.4 na urządzeniach Gigabit Switch Router (routery serii 12000) umożliwia zdalnym atakującym spowodowanie awarii urządzenia poprzez wysłanie źle sformatowanego pakietu Protocol Independent Multicast (PIM).
Risk Assessment
Atakujący mogą wykorzystać tę podatność do zdalnego wywołania awarii urządzenia, co prowadzi do przerwy w dostępności usług sieciowych.
Recommendation
Zaleca się aktualizację oprogramowania Cisco IOS do najnowszej wersji, aby usunąć tę podatność oraz monitorowanie ruchu sieciowego w celu wykrywania potencjalnych ataków.
