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: Console). Supported versions that are affected are 10.3.6.0.0, 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 of this vulnerability can result in takeover of Oracle WebLogic Server. CVSS 3.1 Base Score 9.8 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).

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

A critical unauthenticated remote code execution vulnerability in Oracle WebLogic Server's Console component allows remote attackers to completely compromise the server via HTTP requests without any authentication or user interaction, achieving full confidentiality, integrity, and availability impact.

MitigationApply Oracle's quarterly security patches for CVE-2020-14750 (or upgrade to a patched version) and restrict network access to WebLogic Console/admin interfaces via firewall or authentication mechanisms.

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 version
    Locate the WebLogic installation and determine the exact version number. Check for version files in the installation directory, the Oracle inventory file, or query the server using WLST (WebLogic Scripting Tool) with 'getMajorVersion()' and 'getMinorVersion()' commands. The console about page also displays the version if accessible.
    Affected if The installed version is 10.3.6.0.0, 12.1.3.0.0, 12.2.1.3.0, 12.2.1.4.0, or 14.1.1.0.0 exactly
  2. Confirm WebLogic Console is deployed
    Verify that the WebLogic Console application is deployed and running in your domain. Check the deployed-applications configuration in your domain's config.xml, or query the WebLogic Administration interface, or use WLST to list deployed applications and look for 'console' in the name.
    Affected if The Console application (console.war/console.ear) is deployed and active
  3. Check Console network exposure
    Identify the port the WebLogic Console is listening on (default 7001 for admin console). Review network firewall rules, load balancer settings, and the ListenAddress configuration in config.xml to determine if this port is accessible from network segments outside the trusted admin network.
    Affected if The Console port is reachable from untrusted or external network locations via HTTP

You are affected if your WebLogic Server version matches exactly 10.3.6.0.0, 12.1.3.0.0, 12.2.1.3.0, 12.2.1.4.0, or 14.1.1.0.0, the Console is deployed, and the Console HTTP port is network-accessible without proper segmentation.

Recommended fix High confidence

Apply Oracle October 2020 Critical Patch Update (CPU) to affected versions, or upgrade to WebLogic Server 14.1.1.0.0 with latest CPU applied

  1. Download and apply Oracle Critical Patch Update (CPU) October 2020 which addresses CVE-2020-14750 from Oracle's official patch repository
  2. For Oracle WebLogic Server 10.3.6.0.0: Apply patch following Oracle's README instructions for WLS 10.3.6
  3. For Oracle WebLogic Server 12.1.3.0.0: Apply patch following Oracle's README instructions for WLS 12.1.3
  4. For Oracle WebLogic Server 12.2.1.3.0: Apply patch following Oracle's README instructions for WLS 12.2.1.3
  5. For Oracle WebLogic Server 12.2.1.4.0: Apply patch following Oracle's README instructions for WLS 12.2.1.4
  6. For Oracle WebLogic Server 14.1.1.0.0: Apply patch following Oracle's README instructions for WLS 14.1.1
  7. After applying the patch, restart all WebLogic Server instances to ensure the fix takes effect
  8. Verify the patch was applied successfully by checking the WebLogic Server version and testing the Console functionality
Caveat Applying CPU patches may require downtime for WebLogic Server restarts; test patches in non-production environment first to ensure compatibility with existing applications
