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
Zoho ManageEngine OpManager, OpManager Plus, OpManager MSP, Network Configuration Manager, NetFlow Analyzer, Firewall Analyzer, and OpUtils before 2022-07-27 through 2022-07-28 (125657, 126002, 126104, and 126118) allow unauthenticated attackers to obtain a user's API key, and then access external APIs.

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

Unauthenticated attackers can obtain a user's API key in affected Zoho ManageEngine products (OpManager, OpManager Plus, OpManager MSP, Network Configuration Manager, NetFlow Analyzer, Firewall Analyzer, and OpUtils) due to an authentication bypass flaw. The stolen API key can then be used to access external APIs without proper authorization.

MitigationApply the vendor-released patches (build versions 126118 and later for the mentioned builds) to affected products immediately, as this is an unauthenticated vulnerability with high severity.

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 the installed ManageEngine product
    Access the web interface or check the product name in the application server. Look at the login page or header to confirm which product from the list (OpManager, OpManager Plus, OpManager MSP, Network Configuration Manager, NetFlow Analyzer, Firewall Analyzer, or OpUtils) is running.
    Affected if The product is any of the seven affected products listed in the CVE.
  2. Check the product version number
    Locate the version information in the application's About page, Help menu, or footer of the web interface. The affected versions are 12.5 and 12.6.
    Affected if The installed version is exactly 12.5 or exactly 12.6.
  3. Verify the build version
    Check the build or build number in the application's About or version details section. Vulnerable builds are those prior to build 126118.
    Affected if The build number is below 126118 for versions 12.5 or 12.6.
  4. Assess network exposure of the web interface
    Determine if the application's web interface is accessible from untrusted networks or the internet. This is an unauthenticated vulnerability, so remote attackers can exploit it without any credentials.
    Affected if The web interface is exposed to the internet or untrusted networks without proper network segmentation or authentication proxies.
  5. Review access logs for unusual API key requests
    Examine server access logs for suspicious requests to API endpoints, particularly those that may indicate attempts to bypass authentication or retrieve API keys without valid credentials.
    Affected if There are unauthorized API requests in the logs or evidence of API key exfiltration.

You are affected if you are running any of the seven ManageEngine products at version 12.5 or 12.6 with a build number below 126118, especially if the web interface is network-accessible.
