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 Enterprise Capture product of Oracle Fusion Middleware (component: Client Bundle). 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 T3, IIOP to compromise Oracle WebCenter Enterprise Capture. While the vulnerability is in Oracle WebCenter Enterprise Capture, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in takeover of Oracle WebCenter Enterprise Capture. 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 · moderate confidence

Authenticated remote code execution vulnerability in Oracle WebCenter Enterprise Capture's Client Bundle component, exploitable via T3/IIOP protocols. Low-privilege attackers can achieve complete system compromise (Confidentiality/Integrity/Availability: High) with network access, and the scope change indicates potential impact to additional Oracle products.

MitigationRestrict network access to T3/IIOP ports; apply Oracle Critical Patch Updates when available; if patches are not yet released, consider disabling or firewall-blocking these protocols until remediation is 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 WebCenter Enterprise Capture installation
    Search for WebCenter Enterprise Capture directories or check Oracle Fusion Middleware inventory files (typically under $ORACLE_HOME). Look for 'capture' or 'ecapture' folder names in the Oracle middleware directory structure.
    Affected if Oracle WebCenter Enterprise Capture software is present on the system
  2. Determine installed WebCenter Enterprise Capture version
    Check the version file in the installation directory, typically found in the Client Bundle component path. Common locations include ORACLE_HOME/capture/client/version.txt or the inventory files in $ORACLE_HOME/inventory/ContentsXML/oracle_product.xml.
    Affected if Installed version is exactly 12.2.1.4.0 or exactly 14.1.2.0.0
  3. Verify T3/IIOP protocol availability
    Check WebLogic server configuration files (config.xml) or the WebLogic Administration Console for T3/IIOP protocol enablement. These protocols are typically enabled by default on WebLogic servers that host the Client Bundle component.
    Affected if T3 or IIOP protocols are enabled and accessible on the target server
  4. Confirm network exposure of T3/IIOP ports
    Identify the listening ports for T3 (typically 7001 default) and IIOP (typically 7002 default) using netstat or by reviewing WebLogic server configuration. Verify if these ports are exposed to untrusted networks.
    Affected if T3/IIOP ports are reachable from network segments accessible to low-privilege attackers

User is affected if Oracle WebCenter Enterprise Capture versions 12.2.1.4.0 or 14.1.2.0.0 are installed AND the T3/IIOP protocols are enabled and network-accessible to authenticated attackers.

Mitigation

Restrict network access to T3/IIOP ports; apply Oracle Critical Patch Updates when available; if patches are not yet released, consider disabling or firewall-blocking these protocols until remediation is possible.
