CVE-2008-5524
HighSummary
CAT-QuickHeal w wersji 10.00 oraz prawdopodobnie 9.50, w przypadku użycia Internet Explorer 6 lub 7, umożliwia zdalnym atakującym ominięcie wykrywania złośliwego oprogramowania w dokumencie HTML. Atakujący mogą to osiągnąć, umieszczając nagłówek MZ na początku oraz modyfikując nazwę pliku, aby miała brak rozszerzenia, rozszerzenie .txt lub .jpg.
Risk Assessment
Organizacje mogą być narażone na ataki z wykorzystaniem złośliwego oprogramowania, które nie zostanie wykryte przez oprogramowanie zabezpieczające. To może prowadzić do kompromitacji systemów i utraty danych.
Recommendation
Zaleca się aktualizację oprogramowania CAT-QuickHeal do najnowszej wersji oraz monitorowanie i skanowanie dokumentów HTML pod kątem nietypowych nagłówków i rozszerzeń plików.

Original NVD description (English source)
CAT-QuickHeal 10.00 and possibly 9.50, when Internet Explorer 6 or 7 is used, allows remote attackers to bypass detection of malware in an HTML document by placing an MZ header (aka "EXE info") at the beginning, and modifying the filename to have (1) no extension, (2) a .txt extension, or (3) a .jpg extension, as demonstrated by a document containing a CVE-2006-5745 exploit.
