Veeam Backup Enterprise Manager Vulnerability
(CVE-2024-40715)
This article documents a vulnerability discovered in Veeam Backup Enterprise Manager (VBEM), a supplementary application customers may deploy to manage Veeam Backup & Replication (VBR) using a web console.
Deploying VBEM is optional; not all environments will have it installed. As such, if VBEM was not deployed in your environment, that environment would not be impacted by this vulnerability.
Tip: You can identify if VBEM is installed by checking for the Veeam Backup Enterprise Manager service or by running the following PowerShell command on the Veeam Backup Server to see if VBR reports that it is managed by a VBEM deployment.
