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 if Oracle WebCenter Sites is installed
    Check for running processes or installed services containing 'WebCenter Sites' or 'Fatwire'. On Windows, review installed programs in Programs and Features. On Linux, check application directories or packaging systems.
    Affected if Oracle WebCenter Sites software is present on the system
  2. Determine the installed version
    Locate version documentation or configuration files within the WebCenter Sites installation directory. Common locations include: [install_dir]/config/version.properties, [install_dir]/about.html, or check the product help/about interface. Alternatively, examine HTTP response headers from the WebCenter Sites web interface.
    Affected if The installed version matches 12.2.1.4.0 or 14.1.2.0.0 exactly
  3. Verify HTTP network accessibility
    Test connectivity to the WebCenter Sites HTTP endpoints from external network locations. Use curl or a browser to access the main application URL without authentication credentials.
    Affected if The WebCenter Sites HTTP interface is reachable over the network without authentication

A user is affected if Oracle WebCenter Sites version 12.2.1.4.0 or 14.1.2.0.0 is installed and its HTTP interface is network-accessible without authentication.
