CVE-2017-0037
HighCVSS 8.1KEVSummary
W przeglądarkach Microsoft Internet Explorer 10 i 11 oraz Microsoft Edge występuje problem z myleniem typów w funkcji Layout::MultiColumnBoxBuilder::HandleColumnBreakOnColumnSpanningElement w pliku mshtml.dll. Umożliwia to zdalnym atakującym wykonanie dowolnego kodu za pomocą specjalnie przygotowanej sekwencji tokenów CSS oraz skryptu JavaScript działającego na elemencie TH.
Risk Assessment
Podatność ta stwarza ryzyko zdalnego wykonania kodu, co może prowadzić do przejęcia kontroli nad systemem użytkownika. Atakujący mogą wykorzystać tę lukę do wprowadzenia złośliwego oprogramowania lub kradzieży danych.
Recommendation
Zaleca się aktualizację przeglądarek Internet Explorer i Edge do najnowszych wersji, aby usunąć tę podatność. Dodatkowo, warto rozważyć wdrożenie filtrów zabezpieczających przed złośliwym kodem JavaScript.

Original NVD description (English source)
Microsoft Internet Explorer 10 and 11 and Microsoft Edge have a type confusion issue in the Layout::MultiColumnBoxBuilder::HandleColumnBreakOnColumnSpanningElement function in mshtml.dll, which allows remote attackers to execute arbitrary code via vectors involving a crafted Cascading Style Sheets (CSS) token sequence and crafted JavaScript code that operates on a TH element.
