CVE-2010-2835
HighSummary
Podatność w Cisco IOS oraz Cisco Unified Communications Manager umożliwia zdalnym atakującym spowodowanie awarii usługi (przeładowanie urządzenia lub przerwa w usługach głosowych) poprzez wysłanie żądania SIP REFER z nieprawidłowym nagłówkiem Refer-To. Dotyczy to wersji IOS od 12.2 do 12.4 oraz 15.0 do 15.1, a także różnych wersji CUCM.
Risk Assessment
Organizacje mogą doświadczyć przerw w dostępności usług głosowych, co może prowadzić do zakłóceń w komunikacji i potencjalnych strat finansowych. Atakujący mogą wykorzystać tę podatność do destabilizacji systemów telekomunikacyjnych.
Recommendation
Zaleca się aktualizację urządzeń do najnowszych wersji oprogramowania, które eliminują tę podatność. Należy również monitorować ruch SIP w celu wykrywania podejrzanych żądań.
