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
Unspecified vulnerability in the Portal component in Oracle Application Server 10.1.3 up to 10.1.3.2.0, 10.1.2 up to 10.1.2.2.0, and 9.0.4.3 has unknown impact and attack vectors, aka AS04.

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

Unspecified vulnerability in Oracle Application Server Portal component affecting versions 9.0.4.3, 10.1.2.x through 10.1.2.2.0, and 10.1.3.x through 10.1.3.2.0. The exact vulnerability type and attack vector are not disclosed in the vulnerability note; CVSS 10 indicates potential for complete system compromise (likely remote code execution or authentication bypass). This was part of Oracle's April 2007 Critical Patch Update.

MitigationApply Oracle Critical Patch Update April 2007 (or subsequent relevant patches). Given the age of these Oracle Application Server versions (circa 2007), strongly consider upgrading to a supported Oracle Fusion Middleware version or migrating to a supported platform, as older versions are likely end-of-life and may have additional unpatched vulnerabilities.

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 Application Server installation
    Locate Oracle Application Server binary directories or check for Oracle inventory entries. Common locations include $ORACLE_HOME and /etc/oraInst.loc on Unix or registry entries on Windows.
    Affected if Oracle Application Server is installed and the Portal component is present
  2. Determine Oracle Application Server version
    Run 'opatch lsinventory' or check the version string in $ORACLE_HOME/oraInst.loc, or query the Oracle Inventory using 'lsinventory' command. The version will appear in format like 9.0.4.3, 10.1.2.0.0, 10.1.2.2, 10.1.3.0, or 10.1.3.2.0.
    Affected if The installed version matches exactly 9.0.4.3, 10.1.2.0.0, 10.1.2.0.2, 10.1.2.2, 10.1.3.0, or 10.1.3.2.0
  3. Verify Portal component is configured
    Check if the OracleAS Portal is configured by examining the ORACLE_HOME/portal directory or by querying the Oracle Application Server deployment status. The Portal typically runs on port 7777 or 7778 by default.
    Affected if The Portal component is installed and configured on the affected version
  4. Confirm Portal is accessible and running
    Attempt to access the Portal URL (typically http://hostname:7777/pls/portal or similar) or check running processes for portal-related Java processes.
    Affected if The Portal service is active and responding

The system is affected if Oracle Application Server is installed with version 9.0.4.3, 10.1.2.0.0, 10.1.2.0.2, 10.1.2.2, 10.1.3.0, or 10.1.3.2.0 AND the Portal component is configured and running.
