CVE-2020-1555
HighSummary
W Microsoft Edge (oparty na HTML) występuje podatność na zdalne wykonanie kodu, związana z obsługą obiektów w pamięci przez silnik skryptowy. Atakujący może wykorzystać tę podatność do wykonania dowolnego kodu w kontekście aktualnego użytkownika, co może prowadzić do przejęcia kontroli nad systemem.
Risk Assessment
Podatność stwarza poważne ryzyko dla organizacji, ponieważ atakujący może uzyskać te same uprawnienia co aktualny użytkownik, a w przypadku użytkownika z uprawnieniami administratora, może całkowicie przejąć kontrolę nad systemem.
Recommendation
Zaleca się aktualizację Microsoft Edge do najnowszej wersji, aby usunąć tę podatność oraz wdrożenie dodatkowych środków bezpieczeństwa, takich jak filtrowanie treści i edukacja użytkowników na temat zagrożeń związanych z odwiedzaniem nieznanych stron internetowych.

Original NVD description (English source)
A remote code execution vulnerability exists in the way that the scripting engine handles objects in memory in Microsoft Edge (HTML-based). The vulnerability could corrupt memory in such a way that an attacker could execute arbitrary code in the context of the current user. An attacker who successfully exploited the vulnerability could gain the same user rights as the current user. If the current user is logged on with administrative user rights, an attacker who successfully exploited the vulnerability could take control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. In a web-based attack scenario, an attacker could host a specially crafted website that is designed to exploit the vulnerability through Microsoft Edge (HTML-based) and then convince a user to view the website. The attacker could also take advantage of compromised websites and websites that accept or host user-provided content or a
