Feiten
Veeam heeft kwetsbaarheden verholpen in Veeam Backup & Replication.
Interpretaties
De kwetsbaarheden bevinden zich in de Mount service van Veeam Backup & Replication en de Backup Server, die beide kwetsbaar zijn voor remote code execution (RCE) door geauthenticeerde domeingebruikers. Dit kan leiden tot ongeautoriseerde toegang en manipulatie van gevoelige gegevens binnen de back-upomgeving. Daarnaast is de Veeam Agent voor Microsoft Windows kwetsbaar voor Local Privilege Escalation, wat kan worden misbruikt als een systeembeheerder wordt misleid om een kwaadaardig bestand te herstellen, waardoor een aanvaller verhoogde privileges kan verkrijgen.
Oplossingen
Veeam heeft updates uitgebracht om de kwetsbaarheden te verhelpen. Zie bijgevoegde referenties voor meer informatie.
