Feiten

Microsoft heeft kwetsbaarheden verholpen in Windows.

Interpretaties

Een kwaadwillende kan de kwetsbaarheden misbruiken om aanvallen uit te voeren die kunnen leiden tot de volgende categorieën schade: - Denial-of-Servie (DoS) - Verkrijgen van verhoogde rechten - Omzeilen van beveiligingsmaatregel - Spoofing - Uitvoer van willekeurige code (Gebruikersrechten) Van de kwetsbaarheden met kenmerk CVE-2025-21391 en CVE-2025-21418 meldt Microsoft informatie te hebben dat deze beperkt zijn misbruikt. Deze kwetsbaarheden bevinden zich respectievelijk in Windows Storage en WinSOCK. Succesvol misbruik vereist wel dat de kwaadwillende lokale toegang heeft tot het kwetsbare systeem. Van de kwetsbaarheid met kenmerk CVE-2025-21377 geeft Microsoft aan informatie te hebben dat deze de aandacht heeft van onderzoekers, maar er is (nog) geen publieke Proof-of-Concept (PoC) of exploit bekend. Deze kwetsbaarheid bevindt zich in de wijze waarop omgegaan wordt met NTLMv2. ``` Windows Disk Cleanup Tool: |----------------|------|-------------------------------------| | CVE-ID | CVSS | Impact |
