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 WebCenter Content product of Oracle Fusion Middleware (component: Content Server). Supported versions that are affected are 12.2.1.4.0 and 14.1.2.0.0. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Oracle WebCenter Content. While the vulnerability is in Oracle WebCenter Content, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in takeover of Oracle WebCenter Content. CVSS 3.1 Base Score 9.9 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/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

This is a critical vulnerability in Oracle WebCenter Content's Content Server component that allows low-privileged attackers with network access via HTTP to achieve complete takeover of the affected system. The 'scope change' (S:C) in the CVSS vector indicates the vulnerability enables attacks that extend beyond the vulnerable component to impact additional products in the Oracle Fusion Middleware environment.

MitigationApply the relevant Oracle Critical Patch Update for Oracle WebCenter Content addressing this vulnerability. Until patches are available, restrict network access to Content Server to trusted sources only and implement least-privilege access controls.

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 WebCenter Content installation path
    Locate the Oracle WebCenter Content installation directory, typically under $ORACLE_HOME in the Oracle Fusion Middleware home. Check for the presence of the 'ucm' or 'oracle_webcenter_content' directory structure.
    Affected if Installation directory exists with WebCenter Content components
  2. Determine Content Server version
    Access the Content Server administration interface (typically at /idc/ or /cs/ path) and navigate to the 'About' or 'System Information' page. Alternatively, check version files in the installation directory or use the Oracle Inventory (ORACLE_HOME/inventory/ContentsXML/oraclehome.xml).
    Affected if Installed version equals 12.2.1.4.0 or 14.1.2.0.0 exactly
  3. Verify Content Server component is running
    Check if the Content Server web application is active by accessing the HTTP interface on the configured port (default 16200 or 8080). Confirm the server responds to requests and displays the Content Server login or administration pages.
    Affected if Content Server HTTP interface is accessible and responds
  4. Assess network exposure of Content Server
    Review firewall rules, load balancer configurations, and Oracle WebLogic Server deployment settings to determine if the Content Server HTTP port is exposed to untrusted network segments. Check for any URL access controls or IP restrictions configured at the web server or Oracle Access Manager level.
    Affected if Content Server is reachable from untrusted network addresses

A user is affected if their Oracle WebCenter Content installation is version 12.2.1.4.0 or 14.1.2.0.0 and the Content Server HTTP interface is network-accessible to low-privileged users.
