CVE-2008-5546
HighSummary
VirusBlokAda VBA32 w wersji 3.12.8.5, przy użyciu Internet Explorera 6 lub 7, pozwala zdalnym atakującym na ominięcie wykrywania złośliwego oprogramowania w dokumencie HTML. Możliwe jest to poprzez umieszczenie nagłówka MZ na początku oraz modyfikację nazwy pliku, aby nie miała rozszerzenia, miała rozszerzenie .txt lub .jpg.
Risk Assessment
Organizacja może być narażona na ataki z wykorzystaniem złośliwego oprogramowania, które nie zostanie wykryte przez oprogramowanie zabezpieczające. To może prowadzić do utraty danych lub kompromitacji systemów.
Recommendation
Zaleca się aktualizację oprogramowania VirusBlokAda do najnowszej wersji oraz monitorowanie i skanowanie wszystkich dokumentów HTML przed ich otwarciem. Warto również rozważyć użycie alternatywnych przeglądarek internetowych.
