CVE-2020-1563
HighSummary
W Microsoft Office występuje podatność na zdalne wykonanie kodu, gdy oprogramowanie nieprawidłowo obsługuje obiekty w pamięci. Atakujący, który skutecznie wykorzysta tę podatność, może uruchomić dowolny kod w kontekście aktualnego użytkownika, co w przypadku użytkownika z uprawnieniami administratora może prowadzić do przejęcia kontroli nad systemem.
Risk Assessment
Organizacja narażona jest na poważne ryzyko, ponieważ atakujący może instalować programy, zmieniać lub usuwać dane oraz tworzyć nowe konta z pełnymi uprawnieniami. Użytkownicy z ograniczonymi uprawnieniami mogą być mniej narażeni, ale nadal istnieje ryzyko.
Recommendation
Zaleca się natychmiastowe zastosowanie dostępnych aktualizacji zabezpieczeń dla Microsoft Office oraz edukację użytkowników na temat otwierania plików z nieznanych źródeł.

Original NVD description (English source)
A remote code execution vulnerability exists in Microsoft Office software when the software fails to properly handle objects in memory. An attacker who successfully exploited the vulnerability could run arbitrary code in the context of the current user. If the current user is logged on with administrative user rights, an attacker could take control of the affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights. Exploitation of the vulnerability requires that a user open a specially crafted file with an affected version of Microsoft Office. In an email attack scenario, an attacker could exploit the vulnerability by sending the specially crafted file to the user and convincing the user to open the file.
