CVE-2011-2578
HighSummary
W systemach Cisco IOS 15.1 i 15.2 występuje wyciek pamięci, który pozwala zdalnym atakującym na spowodowanie odmowy usługi poprzez wysyłanie źle sformatowanych pakietów SIP na interfejsie NAT. Problem ten jest znany jako Bug ID CSCts12366.
Risk Assessment
Atakujący mogą wykorzystać tę podatność do wyczerpania zasobów pamięci, co prowadzi do niedostępności usług. Może to wpłynąć na ciągłość działania organizacji i jej infrastrukturę sieciową.
Recommendation
Zaleca się aktualizację systemów Cisco IOS do najnowszej wersji, aby usunąć tę podatność. Dodatkowo, monitorowanie ruchu SIP na interfejsach NAT może pomóc w wykrywaniu i zapobieganiu potencjalnym atakom.
