CVE-2008-2734
HighSummary
W urządzeniach Cisco Adaptive Security Appliance (ASA) 5500 występuje wyciek pamięci w funkcjonalności kryptograficznej, co może prowadzić do awarii usługi. Problem dotyczy wersji 7.2 przed 7.2(4)2, 8.0 przed 8.0(3)14 oraz 8.1 przed 8.1(1)4, gdy są skonfigurowane jako punkt końcowy VPN SSL bez klienta.
Risk Assessment
Zdalni atakujący mogą wykorzystać tę podatność do spowodowania odmowy usługi, co prowadzi do zużycia pamięci i zawieszenia VPN. Może to wpłynąć na dostępność usług w organizacji.
Recommendation
Zaleca się aktualizację urządzeń do najnowszych wersji oprogramowania, aby usunąć tę podatność. Należy również monitorować ruch SSL i HTTP w celu wykrywania potencjalnych ataków.
