CVE-2017-8856
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 · uneditedIn Veritas NetBackup 8.0 and earlier and NetBackup Appliance 3.0 and earlier, there is unauthenticated, 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 · moderate confidenceUnauthenticated remote code execution vulnerability in the bprd (NetBackup Request Daemon) process of Veritas NetBackup 8.0 and earlier and NetBackup Appliance 3.0 and earlier. An attacker can execute arbitrary commands on the target system without any authentication credentials, gaining full system compromise.

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.
-
Identify if NetBackup is installedLook for NetBackup installation directories (typically /usr/openv or C:\Program Files\Veritas) or check for bprd process running via 'ps aux | grep bprd' on Unix or 'tasklist | findstr bprd' on WindowsAffected if NetBackup software is present and bprd process is running
-
Determine NetBackup versionRun 'bpgetconfig' command if available, check /usr/openv/netbackup/version on Unix or registry keys under HKEY_LOCAL_MACHINE\SOFTWARE\Veritas\NetBackup\CurrentVersion on WindowsAffected if Installed version is 8.0 or earlier for NetBackup, or 3.0 or earlier for NetBackup Appliance
-
Verify bprd service is exposedCheck if bprd is listening on network ports (default port 13722) using 'netstat -anp | grep 13722' or 'nmap -p 13722 <target>'Affected if bprd daemon is bound to a network interface and accessible remotely
-
Check network accessibility of bprd portReview firewall rules and network ACLs to determine if port 13722 (or custom configured bprd port) is open to untrusted networksAffected if bprd port is exposed to external/untrusted networks without restriction
A system is affected if NetBackup or NetBackup Appliance version 8.0/3.0 or earlier is installed with the bprd daemon running and accessible over the network.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedUpgrade to a patched version of NetBackup and NetBackup Appliance beyond the affected versions. As a temporary measure, restrict network access to bprd service ports and implement network segmentation to limit exposure.
NetBackup 8.1 or later (or latest available stable release); NetBackup Appliance 3.1 or later
- 1. Identify the current NetBackup version by running 'bpgetconfig' or checking the About section in the NetBackup Administration Console
- 2. Consult the Veritas Support website (support.veritas.com) or release notes to obtain the latest NetBackup version for your platform
- 3. Download the appropriate upgrade package for NetBackup or NetBackup Appliance from Veritas Electronic Software Distribution (ESD)
- 4. Review the Veritas NetBackup Upgrade Guide for your specific version for pre-upgrade requirements such as catalog backups
- 5. Execute the upgrade following the documented upgrade procedure, ensuring proper backups are taken first
- 6. After upgrade, verify the 'bprd' process permissions have been corrected and the service is running correctly
- 7. Confirm the version has been updated by checking 'bpgetconfig' or the Administration Console
