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 Oracle Essbase (component: Security and Provisioning). The supported version that is affected is 21.4. Difficult to exploit vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Essbase. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle Essbase accessible data. CVSS 3.1 Base Score 5.3 (Confidentiality impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:N/A:N).

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

Unauthenticated vulnerability in Oracle Essbase 21.4 Security and Provisioning component allows remote attackers via HTTP to gain unauthorized access to sensitive data. Exploitation is difficult (high complexity) and requires human interaction from a person other than the attacker.

MitigationApply Oracle Critical Patch Update for version 21.4. If immediate patching is not possible, restrict network access to Essbase HTTP interfaces and monitor for suspicious activity.

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 if Oracle Essbase is installed
    Check for Essbase installation directories (commonly under $ORACLE_HOME/essbase) or look for Essbase-related processes: ps -ef | grep -i essbase on Linux, or check Services on Windows for 'Oracle Essbase' services
    Affected if Oracle Essbase software is present on the system
  2. Determine the installed Essbase version
    Check the version file or executable: look for version.txt in the Essbase installation directory, or run 'essbase --version' if available, or check the product details in Oracle Inventory (oratab, Oracle Universal Installer logs)
    Affected if Version is exactly 21.4 (the affected version)
  3. Verify the HTTP interface is enabled
    Check Essbase configuration files (essbase.cfg, httpd.conf, or similar) for HTTP listener settings, or check if ports like 9000-9100 (common Essbase HTTP ports) are listening: netstat -an | grep LISTEN | grep -E '900[0-9]|91[0-9][0-9]'
    Affected if HTTP/HTTPS listener is active and accepting connections
  4. Check network exposure of Essbase HTTP ports
    Run 'netstat -tlnp' or 'ss -tlnp' to list listening ports, identify Essbase HTTP ports (typically 9000, 9100, or configured custom ports), and verify if they are bound to 0.0.0.0 (all interfaces) vs 127.0.0.1 (localhost only)
    Affected if HTTP interface is listening on 0.0.0.0 or all network interfaces and is accessible from untrusted networks

A system is affected if Oracle Essbase version 21.4 is installed with its HTTP interface exposed to the network, allowing unauthenticated remote access to the Security and Provisioning component.

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

Apply Oracle Critical Patch Update for version 21.4. If immediate patching is not possible, restrict network access to Essbase HTTP interfaces and monitor for suspicious activity.

Recommended fix Moderate confidence

Essbase 21.5 or later (or apply Oracle CPU patch for 21.4)

  1. 1. Identify current Oracle Essbase 21.4 installation
  2. 2. Download Oracle Essbase 21.5 or later from Oracle Software Delivery Cloud (edelivery.oracle.com)
  3. 3. Review Oracle Critical Patch Update advisory for CVE-2023-21942 to confirm the specific patch required
  4. 4. Apply the latest Oracle CPU patch for Essbase 21.4, or upgrade to Essbase 21.5 or higher
  5. 5. After upgrade, verify Essbase services start successfully
  6. 6. Validate that Security and Provisioning configurations are intact post-upgrade
Caveat Review Oracle migration documentation for Essbase 21.x upgrades; some configuration changes may be required
