Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Veeam Backup Enterprise Manager allows unauthenticated users to log in as any user to enterprise manager web interface.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

Veeam Backup Enterprise Manager contains an authentication bypass vulnerability that allows unauthenticated remote attackers to gain access to the web interface by impersonating any existing user account. This critical flaw enables complete compromise of the backup management platform without requiring valid credentials.

MitigationApply the vendor-provided security patch immediately. Until patching is possible, restrict network access to the Enterprise Manager web interface to only trusted management networks and monitor for unauthorized access attempts.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Confirm Veeam Backup Enterprise Manager is installed
    Check installed programs or services for Veeam Backup Enterprise Manager. On Windows, review installed applications via Control Panel > Programs and Features, or run: Get-Service | Where-Object {$_.DisplayName -like '*Veeam*'}
    Affected if The software is present on the system
  2. Identify installed Veeam Backup & Replication version
    Open Veeam Backup & Replication console, or check the version via registry at HKLM\SOFTWARE\Veeam\Veeam Backup and Replication\Version, or run: (Get-ItemProperty 'HKLM:\SOFTWARE\Veeam\Veeam Backup and Replication').Version
    Affected if Version number returned is lower than 12.1.2.172
  3. Confirm Enterprise Manager component is deployed
    In Veeam Backup & Replication console, navigate to Inventory > Enterprise Manager, or check services for 'VeeamBackupEnterpriseManager' service status
    Affected if Enterprise Manager service or component is installed and running
  4. Check if Enterprise Manager web interface is network-accessible
    Review firewall rules or network configuration to determine if TCP port 9443 (default Enterprise Manager web UI) is open to untrusted networks. Run: netsh advfirewall firewall show rule name=all | findstr "9443"
    Affected if Port 9443 or the Enterprise Manager web UI is exposed to untrusted/non-management networks
