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
Hitachi Vantara Pentaho Business Analytics Server versions before 9.4.0.1 and 9.3.0.2, including 8.3.x do not correctly protect the Post Analysis service endpoint of the data access plugin against out-of-band XML External Entity Reference. 

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

Hitachi Vantara Pentaho Business Analytics Server contains an XML External Entity (XXE) injection vulnerability in the Post Analysis service endpoint of the data access plugin. The XML parser does not properly disable external entity processing, allowing attackers to craft malicious XML payloads to potentially read local files or perform server-side request forgery (SSRF) attacks.

MitigationUpgrade to Pentaho BA Server version 9.4.0.1, 9.3.0.2, or later which contains the patch. Alternatively, disable external entity processing in the XML parser configuration for the affected data access plugin endpoint.

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 Pentaho BA Server version
    Locate the version information for your Pentaho Business Analytics Server installation (commonly found in version properties files or server startup logs)
    Affected if The installed version is less than 9.3.0.2 or equals 9.4.0.0
  2. Confirm data access plugin is present
    Determine whether the data access plugin is installed and enabled in your Pentaho BA Server environment
    Affected if The data access plugin is present and active in the installation
  3. Check Post Analysis endpoint accessibility
    Verify that the Post Analysis service endpoint of the data access plugin is exposed and accessible on your server
    Affected if The Post Analysis endpoint is reachable via network or local access
  4. Review XML parser configuration
    Examine the XML parser settings for the data access plugin endpoint to determine if external entity processing has been explicitly disabled
    Affected if External entity processing is not disabled in the XML parser configuration for the affected endpoint

Your environment is affected if you run Pentaho BA Server version 9.4.0.0 or any version below 9.3.0.2, with the data access plugin enabled and its Post Analysis endpoint accessible, and the XML parser has not been configured to disable external entity processing.

Generated from the published advisory. Verify against your own configuration.

Check your environment

Paste your version and any relevant configuration and it will be compared against the affected criteria above. Do not include secrets or credentials.

AI-assisted, checked against the advisory. Informational, not a guarantee.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

Upgrade available Upgrade to 9.3.0.2 or later
Fixed in 9.3.0.2
Interim mitigation

Upgrade to Pentaho BA Server version 9.4.0.1, 9.3.0.2, or later which contains the patch. Alternatively, disable external entity processing in the XML parser configuration for the affected data access plugin endpoint.

Recommended fix High confidence

9.4.0.1 or later (9.4.x branch) / 9.3.0.2 or later (9.3.x branch) - recommend latest stable 9.4.x release

  1. 1. Backup your current Pentaho Business Analytics Server installation, including the biserver-ce directory and any custom configurations
  2. 2. Download Pentaho Business Analytics Server version 9.3.0.2 or later (for 9.3.x branch) OR version 9.4.0.1 or later (for 9.4.x branch) from the official Hitachi Vantara support portal
  3. 3. Stop the Pentaho BI Server services
  4. 4. If upgrading within the same major.minor branch, perform an in-place upgrade by running the installer for the new version
  5. 5. If performing a cross-branch upgrade (e.g., 8.3.x to 9.x), perform a fresh installation and migrate custom configurations manually
  6. 6. Restore any custom configurations, plugins, and data connections from the backup
  7. 7. Start the Pentaho BI Server services
  8. 8. Verify the Post Analysis service endpoint is accessible and functioning correctly
Caveat Cross-branch upgrades (e.g., 8.3.x to 9.x) may require configuration migration and custom plugin updates; test thoroughly in non-production environment before production deployment
