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: Samples). Supported versions that are affected are 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 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 6.5 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/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 a vulnerability in its Samples component (versions 12.2.1.4.0 and 14.1.1.0.0) that allows unauthenticated attackers via HTTP to perform unauthorized read, insert, update, or delete operations on a subset of accessible data. The attack requires network access but needs no authentication or user interaction.

MitigationRemove or disable the Samples application from production WebLogic Server deployments, as sample applications are not required in production environments and represent unnecessary attack surface.

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 WebLogic Server installation
    Locate the WebLogic Server installation directory. Common paths include $ORACLE_HOME/wlserver or C:\Oracle\Middleware\wlserver. Check for the presence of the WebLogic installation and its version file or use the WebLogic Administration Console.
    Affected if WebLogic Server is not installed - the check does not apply
  2. Verify the exact WebLogic Server version
    Check the version of the installed WebLogic Server. This can typically be found in the product inventory, installation logs, or by inspecting the manifest file in the wlserver directory. The version must be exactly 12.2.1.4.0 or exactly 14.1.1.0.0 to be affected.
    Affected if The installed version is not 12.2.1.4.0 or 14.1.1.0.0 - the environment is not vulnerable to this specific CVE
  3. Confirm the Samples application is deployed
    Check if the WebLogic Server has the Samples application deployed. This can be done through the WebLogic Administration Console under Deployments, or by checking the deployment configuration files in the domain config directory for a Samples application entry.
    Affected if The Samples application is not deployed - the vulnerability is not present in the environment even if the version matches
  4. Verify the Samples application is accessible
    Confirm the Samples application is in an active or running state and accessible over the network. Check the deployment status in the console or via WLST (WebLogic Scripting Tool). Also verify the HTTP listener is enabled for the admin server or managed servers.
    Affected if The Samples application is not running or not network-accessible - the exploitation vector is not available

The environment is affected by CVE-2022-21252 only if WebLogic Server version is exactly 12.2.1.4.0 or 14.1.1.0.0 AND the Samples application is deployed and accessible over the network.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Remove or disable the Samples application from production WebLogic Server deployments, as sample applications are not required in production environments and represent unnecessary attack surface.

Recommended fix High confidence

Apply Oracle Critical Patch Update (CPU) January 2022 or later; or upgrade to latest WebLogic Server 12.2.1.x or 14.1.x stable release

  1. Check Oracle Critical Patch Updates for the January 2022 release which addresses this vulnerability
  2. Apply the latest Oracle Critical Patch Update (CPU) for WebLogic Server
  3. If running in a production environment, test the patch in a non-production environment first
  4. Verify the Samples component has been updated or removed as part of the patch
  5. After applying the patch, restart the WebLogic Server to ensure the fix takes effect
  6. Validate that the Samples component is no longer accessible or has been secured
Caveat CPU patches are generally low-risk but should be tested in non-production first; some older sample applications may need migration if removed
