CVE-2008-5544
HighSummary
Hacksoft The Hacker w wersjach 6.3.1.2.174 i prawdopodobnie 6.3.0.9.081, w połączeniu z Internet Explorer 6 lub 7, umożliwia zdalnym atakującym ominięcie wykrywania złośliwego oprogramowania w dokumencie HTML. Atakujący mogą to osiągnąć, umieszczając nagłówek MZ na początku dokumentu i modyfikując nazwę pliku, aby nie miała rozszerzenia lub miała rozszerzenie .txt lub .jpg.
Risk Assessment
Organizacje mogą być narażone na ataki z wykorzystaniem złośliwych dokumentów, które mogą przejść niezauważone przez systemy zabezpieczeń. To może prowadzić do infekcji systemów i wycieku danych.
Recommendation
Zaleca się aktualizację oprogramowania do najnowszej wersji oraz wdrożenie dodatkowych mechanizmów wykrywania złośliwego oprogramowania, które mogą identyfikować takie techniki omijania zabezpieczeń.

Original NVD description (English source)
Hacksoft The Hacker 6.3.1.2.174 and possibly 6.3.0.9.081, 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.
