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 in Veeam Backup & Replication allows a low-privileged user with certain roles to perform remote code execution (RCE) by updating existing jobs. These jobs can be configured to run pre- and post-scripts, which can be located on a network share and are executed with elevated privileges by default. The user can update a job and schedule it to run almost immediately, allowing arbitrary code execution on the server.

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

In Veeam Backup & Replication, low-privileged users with certain roles can modify existing backup jobs to add or alter pre- and post-scripts. These scripts run from network shares with elevated privileges, and by scheduling the modified job to run immediately, an attacker can achieve arbitrary code execution on the server.

MitigationRestrict or disable the ability for low-privileged users to modify backup job scripts and schedule configurations. Apply vendor patches when available and audit existing user roles for excessive permissions.

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. Identify the installed Veeam Backup & Replication version
    Check the installed version of Veeam Backup & Replication in the product UI or registry, or use the Veeam PowerShell cmdlet Get-VBRVersion or the About section in the console
    Affected if The installed version is 12.0.0.1402 or higher but lower than 12.3.0.310
  2. Review user role assignments
    In the Veeam console, navigate to Users and Roles or use Get-VBRRoleAssignment to list all users and their assigned roles. Identify accounts that are not Domain Admins or equivalent high-privilege users
    Affected if Any low-privileged user account is assigned a role that permits modification of backup job settings
  3. Enumerate backup jobs with pre- or post-scripts configured
    In the Veeam console, review each backup job's Properties and look for the Scripts section in the Guest Processing settings, or use PowerShell to query jobs with Get-VBRJob and inspect the ScriptConfiguration
    Affected if Any backup job has pre-script or post-script paths configured pointing to custom scripts
  4. Verify low-privileged user access to job modification
    Attempt to modify a backup job configuration using a low-privileged test account, or review role permissions to confirm which roles include Job Edit or Job Configure rights
    Affected if Users with low-privileged roles can successfully edit backup job properties including script configurations

You are affected if your Veeam version is 12.0.0.1402 through 12.3.0.310 and any non-admin user has a role permitting backup job modification, especially if jobs have custom pre/post scripts configured.

Interim mitigation

Restrict or disable the ability for low-privileged users to modify backup job scripts and schedule configurations. Apply vendor patches when available and audit existing user roles for excessive permissions.

Recommended fix High confidence

Veeam Backup & Replication 12.3.0.310 or later

  1. 1. Ensure you have a complete backup of your Veeam Backup & Replication configuration and verify your disaster recovery plan.
  2. 2. Download Veeam Backup & Replication version 12.3.0.310 or later from the official Veeam download portal (www.veeam.com).
  3. 3. Review the Veeam Upgrade Guide for version 12.3 to understand any prerequisites and ensure your environment meets the requirements.
  4. 4. Run the Veeam Backup & Replication installer and select the Upgrade option.
  5. 5. Follow the on-screen prompts to complete the upgrade process.
  6. 6. After upgrade, verify that the Veeam services start successfully and the console is accessible.
  7. 7. Confirm that low-privileged users can no longer modify job scripts without proper authorization by testing with a limited-role account.
