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 prior to versions 9.4.0.1 and 9.3.0.2, including 8.3.x allow a malicious URL to inject content into the Pentaho User Console through session variables. 

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 · high confidence

Reflected Cross-Site Scripting (XSS) vulnerability in Hitachi Vantara Pentaho Business Analytics Server allows attackers to inject malicious content into the Pentaho User Console via URL parameters that are reflected back through session variables. The vulnerability affects versions prior to 9.4.0.1 and 9.3.0.2, including the 8.3.x branch.

MitigationUpgrade to Pentaho BA Server versions 9.4.0.1, 9.3.0.2, or later. If immediate upgrading is not feasible, implement URL filtering and input validation on the server to sanitize request parameters before processing.

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 installation directory
    Locate the Pentaho server installation, typically found at /pentaho-server/ on Linux or C:\pentaho-server\ on Windows, or check your deployment documentation for the custom path.
    Affected if Unable to locate installation directory for version inspection.
  2. Determine installed Pentaho BA Server version
    Check the version file in the Pentaho server directory. Common locations include: pentaho-server/pentaho.version, pentaho-server/tomcat/webapps/pentaho/WEB-INF/classes/version.txt, or look for a version manifest in the server root directory. The version may also be visible in the Pentaho User Console under 'About' or 'Help' > 'About'.
    Affected if Version cannot be determined from the installation.
  3. Compare installed version against affected ranges
    If version is identified, verify whether it falls within: versions < 9.3.0.2 (any 9.x version below 9.3.0.2), version 9.4.0.0 exactly, or any version in the 8.3.x branch.
    Affected if Installed version is 9.4.0.0 OR is less than 9.3.0.2 OR belongs to the 8.3.x branch.
  4. Confirm Pentaho User Console is accessible
    Verify the Pentaho User Console (PUC) web interface is accessible by accessing the server URL, typically at http://hostname:8080/pentaho or https://hostname:8443/pentaho. The XSS vulnerability requires the PUC to be reachable as it occurs through URL parameters reflected in the console.
    Affected if PUC is accessible and installed version matches affected ranges.

The environment is affected if the installed Pentaho BA Server version is 9.4.0.0 or any version below 9.3.0.2 (including 8.3.x branch) and the Pentaho User Console is accessible via web.

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

Upgrade to Pentaho BA Server versions 9.4.0.1, 9.3.0.2, or later. If immediate upgrading is not feasible, implement URL filtering and input validation on the server to sanitize request parameters before processing.

Recommended fix High confidence

9.3.0.2 or 9.4.0.1 (whichever branch applies)

  1. 1. Identify the current Pentaho Business Analytics Server version by checking the version information in the Pentaho User Console or server configuration
  2. 2. Back up the entire Pentaho installation directory, including configuration files, repositories, and any customizations
  3. 3. Download the appropriate fixed version from Hitachi Vantara support portal: upgrade to 9.3.0.2 if on the 9.3.x branch, or 9.4.0.1 if on the 9.4.x branch
  4. 4. Stop the Pentaho Server application and ensure no active sessions are running
  5. 5. Install the upgrade following the standard Pentaho upgrade procedure documented in the official deployment guide
  6. 6. Restore any custom configurations from the backup after the upgrade
  7. 7. Start the Pentaho Server and verify successful startup
  8. 8. Test that the XSS vulnerability is fixed by attempting to inject content through session variables via URL parameters
