CVE-2019-15021
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 · uneditedA security vulnerability exists in the Zingbox Inspector versions 1.294 and earlier, that can allow an attacker to easily identify instances of Zingbox Inspectors in a local area network.
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 confidenceZingbox Inspector versions 1.294 and earlier contain a vulnerability that allows remote attackers on the same local area network to easily discover/identify instances of the Zingbox Inspector service. This is likely due to predictable network behavior, default ports, or identifiable service responses that make network enumeration trivial.

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 Zingbox Inspector is installedCheck system services or running processes for Zingbox Inspector, or look for Zingbox installation directories on the systemAffected if Zingbox Inspector is present on the system
-
Determine the installed versionUse the product's built-in version check command, about dialog, or configuration file to obtain the exact version numberAffected if The version is 1.294 or any earlier version
-
Identify open network ports used by the serviceUse netstat, ss, or a network port scanner to list listening ports on the system where Zingbox Inspector is installedAffected if The service is listening on any network port accessible from other hosts
-
Verify network accessibility from untrusted segmentsFrom a host on a different network segment (or non-management VLAN), attempt to reach the Zingbox Inspector service ports using telnet, nc, or curlAffected if The service responds to requests from network segments that contain untrusted or attacker-accessible hosts
You are affected if Zingbox Inspector version 1.294 or earlier is installed and the service is network-accessible from any untrusted network segment or VLAN.

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 dataMitigate by implementing network segmentation to isolate the Zingbox Inspector from untrusted network segments, applying firewall rules to restrict access to the inspector service from unauthorized network endpoints, and upgrading to a patched version if available.
