CVE-2008-3805
HighSummary
Cisco IOS w wersjach od 12.0 do 12.4 na urządzeniach serii Cisco 10000, uBR10012 i uBR7200 obsługuje zewnętrzne pakiety UDP wysyłane do adresów 127.0.0.0/8, które są przeznaczone do komunikacji IPC wewnątrz urządzenia. To umożliwia zdalnym atakującym spowodowanie odmowy usługi poprzez odpowiednio skonstruowane pakiety UDP.
Risk Assessment
Atakujący mogą zdalnie wywołać przeładowanie urządzenia lub karty linii, co prowadzi do przerwy w dostępności usług. To może wpłynąć na ciągłość działania organizacji.
Recommendation
Zaleca się aktualizację oprogramowania Cisco IOS do najnowszej wersji, aby zniwelować ryzyko związane z tą podatnością. Dodatkowo, warto monitorować ruch UDP i wprowadzić odpowiednie reguły zapory sieciowej.

Original NVD description (English source)
Cisco IOS 12.0 through 12.4 on Cisco 10000, uBR10012 and uBR7200 series devices handles external UDP packets that are sent to 127.0.0.0/8 addresses intended for IPC communication within the device, which allows remote attackers to cause a denial of service (device or linecard reload) via crafted UDP packets, a different vulnerability than CVE-2008-3806.
