CVE-2008-3799
HighSummary
W implementacji protokołu SIP w Cisco IOS w wersjach od 12.2 do 12.4 występuje wyciek pamięci, który może wystąpić, gdy skonfigurowany jest VoIP. Zdalni atakujący mogą spowodować odmowę usługi poprzez wysyłanie nieokreślonych, prawidłowych wiadomości SIP.
Risk Assessment
Organizacja może doświadczyć przerwy w świadczeniu usług głosowych oraz zwiększonego zużycia pamięci, co może prowadzić do awarii systemu. To może wpłynąć na dostępność usług VoIP i zaufanie użytkowników.
Recommendation
Zaleca się aktualizację systemu Cisco IOS do najnowszej wersji, aby usunąć tę podatność oraz monitorowanie ruchu SIP w celu wykrywania potencjalnych ataków.
