CVE-2024-42453Network attack vector

Virtual infrastructure disruption via unchecked management methods

Published Dec 4, 2024 · Updated Dec 4, 2024

Improper authorization in Veeam Backup & Replication 12.2.0.334 and earlier allows remote authenticated users to alter connected hosts. Management-service methods fail to enforce role permissions before accepting host-configuration changes from limited Viewer or Operator accounts. A limited backup-server role is sufficient to power off virtual machines, delete storage files, and change virtual-infrastructure settings.
