Omschrijving
Microsoft heeft een groot aantal kwetsbaarheden verholpen in Windows.
Een kwaadwillende kan de kwetsbaarheden misbruiken om aanvallen uit te voeren die kunnen leiden tot diverse categorieën schade, zoals omschreven in onderstaande tabellen.
Tussen deze kwetsbaarheden zitten een zestal zeer ernstige, welke door Microsoft zijn ingeschaald met een CVSS score van 9 en hoger. Deze kwetsbaarheden bevinden zich in diverse componenten van Windows die bereikbaar en benaderbaar zijn vanaf netwerkverbindingen, zoals http.sys, DHCP, de Kernel en TCP/IP. Door de externe bereikbaarheid en de mogelijkheden tot uitvoer van willekeurige code, is het risico op grootschalig misbruik op korte termijn aanwezig. Op dit moment wordt (nog) geen actief misbruik waargenomen en is (nog) geen publieke Proof-of-Concept (PoC) of exploit bekend, maar het NCSC verwacht deze wel op korte termijn en adviseert daarom deze updates met spoed in te zetten.
