Synopsis

The version of Veeam Backup and Replication installed on the remote Windows host is affected by an authentication bypass vulnerability.

Description

The version of Veeam Backup and Replication installed on the remote Windows host is prior to 11.0.1.1261 P20230227 or 12.x prior to 12.0.0.1420 P20230223.
