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
A vulnerability allowing remote code execution (RCE) on the Backup Server by an authenticated domain user.

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 · moderate confidence

This is a remote code execution vulnerability in a Backup Server product that allows an authenticated domain user to execute arbitrary code on the server. The vulnerability requires prior authentication, meaning the attacker needs valid domain credentials, but once authenticated they can inject and execute malicious code on the backup server infrastructure.

MitigationApply vendor-provided patches immediately and restrict backup server access to only necessary authenticated personnel. Review and audit domain user permissions to ensure the principle of least privilege is enforced.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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. Locate Veeam Backup & Replication installation path
    Check default installation directory C:\Program Files\Veeam\Backup and Replication\Backup\ or search for Veeam.Backup.Manager.exe in Program Files
    Affected if Veeam installation found - proceed to version check
  2. Determine installed Veeam version
    Run Veeam Backup & Replication console and navigate to Help > About, or use PowerShell with command 'Get-VBRServerInfo' after importing VeeamPSSnapin
    Affected if Cannot determine - no Veeam installation found
  3. Compare version to affected range
    Record the full version number shown (format: xx.x.x.xxxx) and compare: affected if version is 12.0.0.1402 or higher AND version is lower than 12.3.2.4165
    Affected if Version falls within 12.0.0.1402 to 12.3.2.4164 inclusive

Environment is affected if Veeam Backup & Replication version is 12.0.0.1402 or higher but lower than 12.3.2.4165, and the server accepts authenticated domain user connections.
