CVE-2008-2441
HighSummary
Cisco Secure ACS w wersjach 3.x przed 3.3(4) Build 12 patch 7, 4.0.x, 4.1.x przed 4.1(4) Build 13 Patch 11 oraz 4.2.x przed 4.2(0) Build 124 Patch 4 nieprawidłowo obsługuje pakiet EAP Response, w którym wartość pola długości przekracza rzeczywistą długość pakietu. To umożliwia zdalnym uwierzytelnionym użytkownikom spowodowanie awarii usługi (crash) CSRadius i CSAuth lub potencjalne wykonanie dowolnego kodu za pomocą spreparowanego pakietu RADIUS.
Risk Assessment
Podatność ta może prowadzić do odmowy usługi, co wpływa na dostępność systemu oraz może umożliwić wykonanie złośliwego kodu, co stanowi poważne zagrożenie dla bezpieczeństwa organizacji.
Recommendation
Zaleca się aktualizację Cisco Secure ACS do najnowszej wersji, która zawiera poprawki bezpieczeństwa, aby zminimalizować ryzyko związane z tą podatnością.
