CVE-2008-3806
HighSummary
Cisco IOS w wersjach od 12.0 do 12.4 na urządzeniach 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 pozwala zdalnym atakującym na spowodowanie odmowy usługi poprzez odpowiednio skonstruowane pakiety UDP.
Risk Assessment
Atakujący mogą doprowadzić do przeładowania urządzenia lub karty linii, co skutkuje przerwaniem usług i potencjalnymi stratami dla organizacji.
Recommendation
Zaleca się aktualizację oprogramowania do najnowszej wersji, aby zniwelować ryzyko związane z tą podatnością oraz monitorowanie ruchu UDP w celu wykrywania potencjalnych ataków.

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-2008-3805.
