Feiten
Microsoft heeft kwetsbaarheden verholpen in Microsoft Exchange Server.
Interpretaties
De kwetsbaarheden in Microsoft Exchange Server zijn het gevolg van onjuiste invoervalidatie en de onjuiste behandeling van speciale elementen, waardoor ongeautoriseerde aanvallers gegevens kunnen manipuleren en communicatie kunnen vervalsen. Dit kan leiden tot ongeautoriseerde toegang, manipulatie van gegevens en blootstelling van gevoelige informatie, wat de integriteit en vertrouwelijkheid van het systeem in gevaar brengt. ``` Microsoft Exchange Server: |----------------|------|-------------------------------------| | CVE-ID | CVSS | Impact | |----------------|------|-------------------------------------| | CVE-2025-33051 | 7.50 | Toegang tot gevoelige gegevens | | CVE-2025-53786 | 8.00 | Verkrijgen van verhoogde rechten | | CVE-2025-25005 | 6.50 | Manipuleren van data | | CVE-2025-25006 | 5.30 | Voordoen als andere gebruiker | | CVE-2025-25007 | 5.30 | Voordoen als andere gebruiker | |----------------|------|-------------------------------------| ```
