CVE-2008-4543
HighSummary
Podatność w Cisco Unity 4.x przed wersją 4.2(1)ES161, 5.x przed wersją 5.0(1)ES53 oraz 7.x przed wersją 7.0(2)ES8, związana z używaniem anonimowej autoryzacji, umożliwia zdalnym atakującym spowodowanie odmowy usługi poprzez wyczerpanie sesji za pomocą dużej liczby połączeń.
Risk Assessment
Organizacja może doświadczyć przerw w dostępności usług, co może prowadzić do zakłóceń w komunikacji i operacjach biznesowych.
Recommendation
Zaleca się aktualizację Cisco Unity do najnowszej wersji oraz rozważenie wprowadzenia silniejszych metod autoryzacji, aby zminimalizować ryzyko ataków typu denial of service.
