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
An issue was discovered in Veritas NetBackup before 10.4. The Multi-Threaded Agent used in NetBackup can be leveraged to perform arbitrary file deletion on protected files.

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

The Multi-Threaded Agent component in Veritas NetBackup versions before 10.4 contains a vulnerability that allows authenticated attackers to bypass intended file protection mechanisms and perform arbitrary file deletion on files that should be protected by the backup system.

MitigationUpgrade NetBackup to version 10.4 or later to address this vulnerability. As a backup system, ensure proper access controls and monitoring are in place until the upgrade can be performed.

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. Confirm NetBackup installation
    Check for NetBackup installation directories (typically /opt/veritas on Linux/Unix or C:\Program Files\Veritas on Windows) or look for nbup.exe, nbemm, or nbrmms processes running
    Affected if NetBackup is installed and running
  2. Identify NetBackup version
    Run command: /opt/veritas/netbackup/bin/nbversion -version (Linux/Unix) or check Add/Remove Programs for version (Windows), or use: nbgetconfig -M hostname (requires admin access)
    Affected if Installed version is lower than 10.4 (e.g., 10.3.x, 10.2.x, 10.1.x, etc.)
  3. Verify Multi-Threaded Agent is enabled
    Check NetBackup configuration for nbpem or nbrb processes (Policy Execution Manager and Resource Broker - components of the Multi-Threaded Agent), or review bp.conf (Linux/Unix) or registry (Windows) for related settings
    Affected if Multi-Threaded Agent processes (nbpem, nbrb) are running or enabled in the configuration
  4. Check file protection policies
    Review NetBackup backup policies to identify any file-level protection settings (file lists, exclude lists, or protected file paths configured in the policy attributes)
    Affected if Any backup policies with protected file paths or file exclusion rules are defined

User is affected if NetBackup version is confirmed to be below 10.4 AND the Multi-Threaded Agent component is enabled with active backup policies containing protected file configurations.

Upgrade available Upgrade to 10.4 or later
Fixed in 10.4
Interim mitigation

Upgrade NetBackup to version 10.4 or later to address this vulnerability. As a backup system, ensure proper access controls and monitoring are in place until the upgrade can be performed.

Recommended fix Moderate confidence

NetBackup 10.4

  1. 1. Identify the current NetBackup version by running 'nbmenu' or checking the NetBackup administration console, or by running '/usr/openv/netbackup/bin/nbversion' on the master server
  2. 2. If version is below 10.4, plan for an upgrade to NetBackup 10.4 or later
  3. 3. Review Veritas NetBackup 10.4 release notes and upgrade documentation at www.veritas.com for comprehensive upgrade procedures
  4. 4. Perform a full backup of the NetBackup environment before initiating the upgrade
  5. 5. Execute the upgrade following Veritas recommended practices, ensuring the Multi-Threaded Agent component is properly updated
  6. 6. After upgrade, verify the NetBackup version is 10.4 or later using the version check command
  7. 7. Validate that the Multi-Threaded Agent is functioning correctly and that the arbitrary file deletion vulnerability is remediated
Caveat Review release notes for any configuration changes or deprecated features between your current version and 10.4; test upgrades in a staging environment first
