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. Locate WebLogic Server installation
    Check common installation directories such as $ORACLE_HOME, /u01/oracle/weblogic, or C:\Oracle\Middleware, and look for the wlserver directory structure.
    Affected if WebLogic Server is installed in any directory on the system.
  2. Identify installed WebLogic Server version
    In the installation directory, locate the file PRODUCT_HOME/wlserver_14.1.1.0/server/lib/weblogic.jar or check the inventory file for the exact version string. Run: java -jar wlserver_14.1.1.0/server/lib/weblogic.jar -version
    Affected if The installed version is exactly 12.2.1.4.0 or exactly 14.1.1.0.0.
  3. Verify Console component is enabled
    Check the WebLogic Server configuration file config.xml in the domain directory for a <console-enabled>true</console-enabled> entry under the Administration Server configuration, or attempt to access the Console URL (typically port 7001/7002 at /console
    Affected if The Console is enabled and accessible on the network.
  4. Confirm network exposure of Console
    Review the Administration Server network listen address in config.xml. Check if the listen-address is set to 0.0.0.0 or a publicly accessible IP, and verify firewall rules allow access to the Console port from untrusted networks.
    Affected if The Console listens on all interfaces (0.0.0.0) or is accessible from untrusted network segments.

A system is affected if it runs Oracle WebLogic Server version 12.2.1.4.0 or 14.1.1.0.0 with the Console component enabled and network accessible to attackers.
