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
A SQL injection vulnerability in /client/api/json/v2/nfareports/compareReport in Zoho ManageEngine NetFlow Analyzer 12.3 allows attackers to execute arbitrary SQL commands via the DeviceID parameter.

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

A SQL injection vulnerability exists in Zoho ManageEngine NetFlow Analyzer 12.3 within the /client/api/json/v2/nfareports/compareReport API endpoint. The DeviceID parameter is not properly sanitized, allowing attackers to inject arbitrary SQL commands. With a CVSS score of 9.8, this critical vulnerability can lead to full database compromise and potentially remote code execution.

MitigationApply the vendor patch for CVE-2019-12196 immediately. If no patch is available, implement input validation and parameterized queries for the DeviceID parameter as an interim mitigation, and consider restricting network access to the affected API endpoint.

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 NetFlow Analyzer installation
    Locate the Zoho ManageEngine NetFlow Analyzer application on the system and verify its presence
    Affected if The application is installed and running
  2. Check installed version
    Use the product's built-in version check mechanism or examine the application metadata to determine the exact version number
    Affected if The installed version is exactly 12.3
  3. Verify API endpoint exposure
    Check if the web interface exposes the /client/api/json/v2/nfareports/compareReport endpoint
    Affected if The endpoint is accessible over the network

A system is affected if Zoho ManageEngine NetFlow Analyzer version 12.3 is installed and the compareReport API endpoint is exposed, allowing unauthenticated injection through the DeviceID parameter.
