Veeam Software Security Commitment

Veeam® is committed to ensuring its products protect customers from potential risks. As part of that commitment, we operate a Vulnerability Disclosure Program (VDP) for all Veeam products and perform extensive internal code audits. When a vulnerability is identified, our team promptly develops a patch to address and mitigate the risk. In line with our dedication to transparency, we publicly disclose the vulnerability and provide detailed mitigation information. This approach ensures that all potentially affected customers can quickly implement the necessary measures to safeguard their systems. It's important to note that once a vulnerability and its associated patch are disclosed, attackers will likely attempt to reverse-engineer the patch to exploit unpatched deployments of Veeam software. This reality underscores the critical importance of ensuring that all customers use the latest versions of our software and install all updates and patches without delay.

Article Applicability

This article documents vulnerabilities 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 wouldnot be impacted by these vulnerabilities.

---

Tip: You can identify if VBEM is installed by checking for theVeeam 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.

Vulnerability testing was only performed against actively supported versions of Veeam Backup & Replication.

Solution

All vulnerabilities documented in this article were fixed in Veeam Backup Enterprise Manager 12.1.2.172, which is****packaged with:

• Veeam Backup & Replication 12.1.2 (build 12.1.2.172)

More Information

Vulnerability Mitigation

For customers who are unable to upgrade Veeam Backup Enterprise Manager to 12.1.2.172 immediately, consider the following:

• This vulnerability can be mitigated by halting the Veeam Backup Enterprise Manager software.
  To do this, stop and disable the following services:
  Note: Disabling the services will not prevent installation of the 12.1.2 update. However, after updating, you’ll need to reset the services back to Automatic startup.

  • VeeamEnterpriseManagerSvc (Veeam Backup Enterprise Manager)
  • VeeamRESTSvc (Veeam RESTful API Service)
    **Note:**On servers where both VBEM and VBR are installed, there will be two services with similar names. The service named ‘Veeam Backup Server RESTful API Service’ belongs to the Veeam Backup & Replication software and does not need to be stopped as part of this mitigation.
    This can be achieved using the following PowerShell commands:

  Set-Service -StartupType Disabled VeeamEnterpriseManagerSvc
  Set-Service -StartupType Disabled VeeamRESTSvc
  Stop-Service VeeamEnterpriseManagerSvc
  Stop-Service VeeamRESTSvc

Copy

• Veeam Backup Enterprise Manager can be upgraded to version 12.1.2.172 without the need to upgrade Veeam Backup & Replication immediately. Veeam Backup Enterprise Manager is compatible with managing Veeam Backup & Replication servers running an older version than Veeam Backup Enterprise Manager.
  **
  Limitation: **Although a newer build of VBEM can manage an older VBR build, so long as that VBR server remains on an older build, you cannot edit jobs that are managed by backup servers of earlier versions using the VBEM web console. This limitation also affects the ability to create and modify existing jobs via the self-service portal.
• Veeam Backup Enterprise Manager can be uninstalled if it is not in use.
