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 · uneditedVeeam Backup Enterprise Manager allows account takeover via NTLM relay.
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 confidenceVeeam Backup Enterprise Manager contains a vulnerability that allows attackers to perform NTLM relay attacks, potentially leading to unauthorized account takeover. The vulnerability exploits the NTLM authentication mechanism used by the application, enabling an attacker to intercept and relay authentication credentials to gain unauthorized access to user accounts.

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 checksWork through these to decide whether this CVE applies to you.
-
Confirm Veeam Backup Enterprise Manager is installedOpen Windows Programs and Features (appwiz.cpl) and look for 'Veeam Backup Enterprise Manager' or check if port 9396/9397 (typical EM ports) is listening on the serverAffected if The application is not installed, the vulnerability does not apply
-
Identify the installed Veeam versionOpen Veeam Backup & Replication console, go to Help > About, or run 'Get-VBRServer' in PowerShell, or check registry: HKLM\SOFTWARE\Veeam\Veeam Backup & Replication\VersionAffected if Version is 12.1.2.172 or higher, the vulnerability is patched; any version below 12.1.2.172 is affected
-
Verify NTLM authentication is enabledCheck Windows Local Security Policy (secpol.msc) > Security Options > Network security: LAN Manager authentication level, or check registry: HKLM\SYSTEM\CurrentControlSet\Control\Lsa\LmCompatibilityLevelAffected if NTLMv1 or NTLMv2 with LM compatibility is enabled and the server accepts NTLM authentication, the relay vector exists
If Veeam Backup Enterprise Manager is installed with a version below 12.1.2.172 and the server accepts NTLM authentication, the environment is vulnerable to NTLM relay attacks.

dbcve · scoped12.1.2.172
Apply the vendor-provided security update for Veeam Backup Enterprise Manager. Additionally, implement network-level protections such as SMB signing and Extended Protection for Authentication (EPA) to mitigate NTLM relay vectors.
Veeam Backup & Replication 12.1.2.172
- Verify current Veeam Backup & Replication version is below 12.1.2.172
- Download Veeam Backup & Replication version 12.1.2.172 or later from the official Veeam download portal
- Review Veeam Upgrade Guide for version 12.1.2.172 for pre-upgrade requirements
- Create a full backup of the Veeam configuration database
- Stop all Veeam services if required by upgrade procedure
