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
Vulnerability in the Oracle WebLogic Server product of Oracle Fusion Middleware (component: Sample apps). Supported versions that are affected are 12.1.3.0.0, 12.2.1.3.0, 12.2.1.4.0 and 14.1.1.0.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle WebLogic Server. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle WebLogic Server, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle WebLogic Server accessible data as well as unauthorized read access to a subset of Oracle WebLogic Server accessible data. CVSS 3.1 Base Score 6.1 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N).

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

Oracle WebLogic Server contains vulnerable sample applications that can be exploited via HTTP by unauthenticated attackers. The vulnerability allows unauthorized read and limited write/delete access to WebLogic Server data, and due to scope changes, may impact additional products in the environment. Exploitation requires human interaction.

MitigationRemove or disable the sample applications from the Oracle WebLogic Server deployment, or apply the relevant Oracle Critical Patch Update for this CVE. Restrict network access to sample app endpoints if removal is not immediately possible.

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 WebLogic Server installation
    Locate WebLogic installation directory by checking ORACLE_HOME or BEA_HOME environment variables, or search for wlserver or WebLogic Server executable files such as startWebLogic.sh or startWebLogic.cmd
    Affected if WebLogic Server is not installed on this system
  2. Determine installed WebLogic Server version
    Check the version of the WebLogic Server installation. Common locations include: the registry file in the installation directory, the manifest in the wlserver.jar file, or the product version displayed when starting the server. Compare your version against these exact values: 12.1.3.0.0, 12.2.1.3.0, 12.2.1.4.0, or 14.1.1.0.0
    Affected if The installed version matches exactly one of the four affected versions (12.1.3.0.0, 12.2.1.3.0, 12.2.1.4.0, or 14.1.1.0.0)
  3. Verify presence of sample applications
    Inspect the WebLogic installation for sample application directories or WAR files. Common sample app locations include: wlserver/samples/server, or look for directories named 'samples', 'examples', or 'demos' within the WebLogic home directory. Also check the Administration Console for deployed sample applications
    Affected if Sample applications or sample application directories exist in the WebLogic deployment
  4. Check network exposure of sample app endpoints
    Test HTTP access to known sample application URLs such as /sample/, /examples/, or /console.help/. Use curl or a browser to attempt access to these endpoints over HTTP from an unauthenticated perspective. Also review the deployment descriptors (weblogic.xml) for any url-pattern mappings to sample applications
    Affected if Sample application HTTP endpoints are accessible without authentication

Your environment is affected if you have Oracle WebLogic Server version 12.1.3.0.0, 12.2.1.3.0, 12.2.1.4.0, or 14.1.1.0.0 deployed with sample applications still present and accessible via HTTP.
