Omschrijving
Microsoft heeft kwetsbaarheden verholpen in diverse Azure componenten.
Een kwaadwillende kan de kwetsbaarheden misbruiken om een Denial-of-Service te veroorzaken, beveiligingsmaatregelen te omzeilen of zich verhoogde rechten toe te kennen en zo mogelijk toegang te krijgen tot gegevens waartoe de kwaadwillende aanvankelijk niet is geautoriseerd.
De ernstigste kwetsbaarheden bevonden zich in de OpenAI agent en Entra provisioning. Deze kwetsbaarheden zijn echter door Microsoft centraal reeds verholpen en slechts opgenomen ter informatie. Er zijn voor deze kwetsbaarheden geen acties vereist.
