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 Oracle Enterprise Manager Base Platform version
    Run 'emctl status agent' or check the Oracle Enterprise Manager administration console to retrieve the installed version of the Base Platform
    Affected if The installed version matches 13.5.0.0 or 24.1.0.0.0 exactly
  2. Verify Metadata Plugin is deployed
    Access the Enterprise Manager console, navigate to the Plugins section, or run 'emcli list_plugins' to confirm whether the Metadata Plugin is installed
    Affected if The Metadata Plugin appears in the list of installed plugins
  3. Confirm Metadata Plugin is enabled
    In the Enterprise Manager console, check the Metadata Plugin status under the Extensibility or Plugins management section
    Affected if The Metadata Plugin status shows as enabled or running
  4. Check network accessibility of Enterprise Manager console
    Review network configuration or firewall rules to determine if the Enterprise Manager HTTPS interface is exposed to network attackers
    Affected if The Enterprise Manager console is reachable over HTTPS from untrusted or external networks

The environment is affected if Oracle Enterprise Manager Base Platform version 13.5.0.0 or 24.1.0.0.0 is running with the Metadata Plugin enabled and the console is network-accessible.
