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
In Veritas NetBackup 8.0 and earlier and NetBackup Appliance 3.0 and earlier, there is unauthenticated file copy and arbitrary remote command execution using the 'bprd' process.

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

Veritas NetBackup 8.0 and earlier and NetBackup Appliance 3.0 and earlier contain an unauthenticated remote code execution vulnerability in the bprd (NetBackup Request Daemon) process, allowing attackers to copy files and execute arbitrary commands without any authentication.

MitigationUpgrade to patched versions of NetBackup and NetBackup Appliance. Until patched, restrict network access to the bprd service port (typically 13782/tcp) via firewall or disable external access.

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. Identify NetBackup installation
    Check for NetBackup installation directories (e.g., /usr/openv/netbackup on Linux/Unix, or C:\Program Files\Veritas\NetBackup on Windows) and look for bprd binary or running processes
    Affected if NetBackup software is present on the system
  2. Determine NetBackup version
    Run command 'bp_get_config -version' or check version file in installation directory (version.txt or similar), or use 'bpminlicense -h' to retrieve version information
    Affected if Installed version is 8.0 or lower for NetBackup, or 3.0 or lower for NetBackup Appliance
  3. Verify bprd process is running
    Check for bprd process: on Linux/Unix run 'ps -ef | grep bprd', on Windows check services or tasklist for bprd.exe
    Affected if bprd daemon process is active and listening
  4. Check network exposure of bprd port
    Verify if port 13782/tcp is listening and accessible from network: run 'netstat -an | grep 13782' or 'nmap -p 13782 <target>' from external perspective
    Affected if Port 13782/tcp is open and exposed to untrusted networks

The environment is affected if NetBackup or NetBackup Appliance version 8.0 or below (or 3.0 or below for Appliance) is installed with bprd service accessible on port 13782/tcp.

dbcve · scoped
Upgrade available Upgrade to a release after 8.0
Interim mitigation

Upgrade to patched versions of NetBackup and NetBackup Appliance. Until patched, restrict network access to the bprd service port (typically 13782/tcp) via firewall or disable external access.

Recommended fix Moderate confidence

NetBackup 8.1 or later; NetBackup Appliance 3.1 or later (or latest available stable releases)

  1. 1. Identify the current NetBackup version by running 'nbversion' or checking the /usr/openv/netbackup/version file
  2. 2. Identify the current NetBackup Appliance version by accessing the Appliance Web Console or running 'nbac --version'
  3. 3. For NetBackup: Schedule an upgrade to NetBackup 8.1 or later (recommended: latest available 8.x release)
  4. 4. For NetBackup Appliance: Schedule an upgrade to NetBackup Appliance 3.1 or later (recommended: latest available 3.x release)
  5. 5. Download the appropriate upgrade package from Veritas Support (https://www.veritas.com/support/en_US.html)
  6. 6. Review Veritas NetBackup Upgrade Guide for detailed upgrade procedures specific to your environment
  7. 7. Perform a full backup of the NetBackup catalog and configuration before upgrading
  8. 8. Apply the upgrade during a scheduled maintenance window following Veritas documented procedures
Caveat Review Veritas compatibility lists and upgrade guide for any compatibility changes with existing backup policies, operating systems, or database agents before upgrading
