CVE-2015-6551
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 · uneditedVeritas NetBackup 7.x through 7.5.0.7 and 7.6.0.x through 7.6.0.4 and NetBackup Appliance through 2.5.4 and 2.6.0.x through 2.6.0.4 do not use TLS for administration-console traffic to the NBU server, which allows remote attackers to obtain sensitive information by sniffing the network for key-exchange packets.
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 confidenceVeritas NetBackup administration console traffic to the NBU server does not use TLS encryption, allowing remote attackers to intercept sensitive information (credentials, administrative commands) via network sniffing of key-exchange packets.

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 NetBackup product typeDetermine whether the system is running NetBackup Appliance or NetBackup server software. On the appliance, log in to the management interface or run 'nbversion' if available. On the server, run 'bpgetconfig' or check the installation directory for version files.Affected if The installed product and version match any of the versions listed in the affected products and versions for CVE-2015-6551 (appliance 1.1.0.1 through 2.6, or NetBackup 7.0 through 7.5.0.7).
-
Locate the administration console serviceIdentify if the NetBackup Administration Console (typically using Java GUI or nbadmin web interface) is configured. Check for listening services on ports commonly used by NetBackup: 1556 (bpcd), 13722, 13724, or 443/80 for web-based consoles. Use 'netstat -an | grep -E "1556|13722|13724"' or similar network scanning from the server.Affected if The administration console service is running and listening on network ports, making it reachable for remote connection attempts.
-
Verify TLS configuration for admin trafficExamine the NetBackup configuration for encryption settings. Check the 'bprd.conf' or 'bp.conf' files (typically in /usr/openv/netbackup on Unix or C:\Program Files\VERITAS\NetBackup\ on Windows) for ENCRYPTION and USE_TLS directives. On the appliance, access the security settings via the management GUI or CLI.Affected if The configuration does not enforce TLS encryption for administrative sessions, or USE_TLS is set to disabled or not configured at all for the administration console traffic.
-
Capture test traffic to confirm encryption statusUse a packet capture tool (such as tcpdump or Wireshark) on the network interface servicing the admin console traffic while performing administrative actions (like logging in). Examine the captured packets for plain-text credentials or unencrypted command traffic.Affected if Network packets show plaintext credentials, administrative commands, or session data without TLS/SSL wrapping (no port 443 or STARTTLS indicators, and no encryption in the payload).
A system is affected if it runs any of the listed vulnerable versions AND the administration console is network-accessible AND TLS encryption is not enforced for admin traffic.

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.
From vendor dataEnable TLS encryption for NetBackup administration console traffic, or upgrade to a patched version (7.5.0.8+, 7.6.0.5+, or appliance versions 2.5.5+, 2.6.0.5+) that includes mandatory TLS. Network segmentation can serve as a compensating control.
