CVE-2022-21292
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 · uneditedVulnerability 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 access to critical data or complete access to all Oracle WebLogic Server accessible data. CVSS 3.1 Base Score 7.5 (Confidentiality impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/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 confidenceOracle WebLogic Server contains an unauthenticated information disclosure vulnerability in its Samples component. An attacker with network access via HTTP can exploit this to gain unauthorized access to critical or all accessible data on the server. The CVSS vector indicates no authentication required and high confidentiality impact with low attack complexity.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify WebLogic Server versionCheck the installed Oracle WebLogic Server version using the Oracle Inventory or by inspecting the weblogic.Server class version (typically found in $ORACLE_HOME/wlserver/server/lib/weblogic.jar or via the WebLogic Administration Console under 'Servers' > 'Monitoring' > 'General'). Compare against affected versions 12.2.1.4.0 and 14.1.1.1.0.Affected if The installed version exactly matches 12.2.1.4.0 or 14.1.1.0.0 (these are the only affected versions listed).
-
Determine if Samples component is deployedCheck if the WebLogic Samples application is deployed. This is typically located under $ORACLE_HOME/wlserver/samples/server/examples/build or accessed via the WebLogic Administration Console under 'Deployments' > 'Samples'. Inspect the deployment configuration files and check for an active Samples application ear/war.Affected if The Samples application is deployed and in an 'Active' or 'Running' state in WebLogic.
-
Verify Samples endpoint accessibilityAttempt to access the Samples component endpoints via HTTP. Common paths include /examples/ or /sample-app/ under the server's HTTP port. Check if the HTTP listener on the WebLogic port (default 7001) responds to requests targeting sample-related URL paths without requiring authentication.Affected if The HTTP port is externally accessible and the Samples endpoint responds without authentication.
-
Check network exposure of WebLogic HTTP portReview firewall rules, network ACLs, and WebLogic network channel configurations to determine if the HTTP port (typically 7001) is bound to a publicly accessible network interface or is reachable from untrusted networks.Affected if The WebLogic HTTP port is reachable from untrusted network segments or exposed to the internet.
You are affected only if you run WebLogic Server version 12.2.1.4.0 or 14.1.1.0.0, the Samples component is deployed and active, and the HTTP port hosting Samples is network-accessible to untrusted users.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedDisable or remove the Samples component from production Oracle WebLogic Server deployments. Apply Oracle's official patch when available. If Samples are required, restrict network access to trusted networks only.
Oracle WebLogic Server 12.2.1.4.0 and 14.1.1.0.0 should be upgraded to the latest available patched versions as specified in Oracle's CPU advisory containing CVE-2022-21292
- 1. Check Oracle's Critical Patch Update (CPU) advisory for January 2022 or subsequent CPUs for CVE-2022-21292 patch availability
- 2. Download the applicable security patch from Oracle Support (My Oracle Support) using the patch ID referenced in the CPU advisory
- 3. Review Oracle's workaround documentation - consider disabling or removing the 'Samples' component if not in use
- 4. Apply the patch in a test environment first following Oracle's standard patching procedures
- 5. Verify the patch was applied successfully and the vulnerability is remediated
- 6. Deploy the patched version to production
