Omschrijving

Microsoft heeft kwetsbaarheden verholpen in diverse Office producten.

Een kwaadwillende kan de kwetsbaarheden misbruiken om willekeurige code uit te voeren in de context van het slachtoffer en daarmee mogelijk toegang krijgen tot gevoelige gegevens.

De kwetsbaarheid met kenmerk CVE-2025-29794 in Microsoft SharePoint stelt een kwaadwillende in staat om willekeurige code over een netwerk uit te voeren. Een geauthenticeerde kwaadwillende kan deze kwetsbaarheid misbruiken, en hiervoor zijn geen verhoogde rechten vereist.

De kwetsbaarheid met kenmerk CVE-2025-29822 in Microsoft OneNote stelt een kwaadwillende in staat om lokaal een beveiligingsfunctie te omzeilen. Voor succesvol misbruik moet de kwaadwillende het slachtoffer misleiden om een malafide bestand te openen en vervolgens op een speciaal vervaardigde URL te klikken.
