CVE-2008-5023
HighSummary
Firefox w wersjach 3.x przed 3.0.4, 2.x przed 2.0.0.18 oraz SeaMonkey w wersjach 1.x przed 1.1.13 umożliwiają zdalnym atakującym obejście mechanizmu ochrony dla zasad kodu i wykonanie dowolnego skryptu za pomocą właściwości CSS -moz-binding w podpisanym pliku JAR.
Risk Assessment
Atakujący mogą wykorzystać tę podatność do uruchomienia złośliwego kodu w kontekście zaufanego źródła, co może prowadzić do kradzieży danych lub przejęcia kontroli nad systemem użytkownika.
Recommendation
Zaleca się aktualizację przeglądarek Firefox i SeaMonkey do najnowszych wersji, aby usunąć tę podatność oraz wprowadzenie dodatkowych środków bezpieczeństwa, takich jak monitorowanie i ograniczenie użycia podpisanych plików JAR.
