CVE-2008-5538
HighSummary
Prevx Prevx1 w wersji 2, przy użyciu Internet Explorera 6 lub 7, umożliwia zdalnym atakującym ominięcie wykrywania złośliwego oprogramowania w dokumencie HTML poprzez umieszczenie nagłówka MZ na początku oraz modyfikację nazwy pliku, aby miała (1) brak rozszerzenia, (2) rozszerzenie .txt lub (3) rozszerzenie .jpg.
Risk Assessment
Organizacja może być narażona na ataki z wykorzystaniem złośliwego oprogramowania, które nie zostanie wykryte przez systemy zabezpieczeń, co może prowadzić do utraty danych lub kompromitacji systemów.
Recommendation
Zaleca się aktualizację przeglądarek internetowych do najnowszych wersji oraz wdrożenie dodatkowych mechanizmów zabezpieczeń, aby zminimalizować ryzyko związane z wykrywaniem złośliwego oprogramowania.
