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 Security component of Oracle Database server 9.0.1.5, 9.0.1.5 FIPS, 9.2.0.6, and 10.1.0.4 has unspecified impact and attack vectors, as identified by Oracle Vuln# DB21.

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 the Security component of Oracle Database server versions 9.0.1.5 through 10.1.0.4 with CVSS score of 9 indicates a critical flaw in authentication, authorization, or encryption mechanisms. The 'unspecified' nature means exact technical details are not disclosed in the advisory, but the critical severity suggests potential for complete database compromise.

MitigationApply Oracle Critical Patch Update (CPU) for January 2006 or later, or migrate to a supported Oracle Database version since 9i/10g are end-of-life. Evaluate compensating controls such as network segmentation and strict access controls until remediation.

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 Database version
    Connect to the database as a privileged user and run: SELECT VERSION FROM V$INSTANCE; or check the ORACLE_HOME/oratab file
    Affected if Version matches 9.0.1.5, 9.2.0.6, or 10.1.0.4 exactly as listed in affected versions
  2. Verify Oracle Database is running
    Check for Oracle Database processes: ps -ef | grep pmon or check Windows services for OracleService*
    Affected if Oracle Database process is active, making the Security component accessible
  3. Confirm database is network accessible
    Check listener status with lsnrctl status or review sqlnet.ora for authentication settings
    Affected if Database accepts remote connections, exposing the Security component to potential exploitation
  4. Check if Oracle Advanced Security options are in use
    Review init.ora or spfile for USE_*_SECURITY parameters
    Affected if Any Oracle Security component configuration is present (required for the vulnerability to apply)
  5. Review recent authentication events
    Examine DBA_USERS and failed login attempts in SELECT * FROM DBA_AUDIT_TRAIL or alert.log
    Affected if Evidence of authentication anomalies exists (indicating possible exploitation attempt)

Environment is affected if Oracle Database Server version 9.0.1.5, 9.2.0.6, or 10.1.0.4 is installed and the Security component is accessible, given the critical severity and unspecified nature of this 2006 vulnerability.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Apply Oracle Critical Patch Update (CPU) for January 2006 or later, or migrate to a supported Oracle Database version since 9i/10g are end-of-life. Evaluate compensating controls such as network segmentation and strict access controls until remediation.

Recommended fix Moderate confidence

Upgrade to a currently supported Oracle Database release such as 19c Long Term or 21c. Oracle 9i and 10g are no longer supported.

  1. 1. Determine your current Oracle Database version and platform.
  2. 2. Plan a database upgrade to a currently supported Oracle Database release (11g R2, 12c, 19c, or 21c are potential targets depending on your timeline).
  3. 3. Review Oracle's upgrade documentation for your target version at http://www.oracle.com/pls/db102/portal.alle_warnings?action=100,101,102_1080 or http://docs.oracle.com/ for newer versions.
  4. 4. Perform a full backup of the existing database before upgrade.
  5. 5. Test the upgrade in a non-production environment first.
  6. 6. Execute the upgrade following Oracle's recommended procedures.
  7. 7. After upgrade, apply the latest Oracle Critical Patch Update (CPU) for your new version.
Caveat Major version upgrades require significant testing; legacy applications may need compatibility settings or code changes.
