CVE-2021-45446: Pentaho Business Analytics Server - Exposure of Information Through Directory Listing

A vulnerability in Hitachi Vantara Pentaho Business Analytics Server versions before 9.2.0.2 and 8.3.0.25 does not cascade the hidden property to the children of the Home folder.  This directory listing provides an attacker with the complete index of all the resources located inside the directory.

Security readout for executives and security teams

Plain-English summary

Pentaho Business Analytics Server could reveal a full index of resources inside the Home folder because hidden status was not inherited by child items. An authenticated low-privilege user could learn resource names or structure that should have remained hidden. The issue affects versions before 9.2.0.2 and 8.3.0.25.

Executive priority

Treat as a moderate-priority confidentiality issue. Prioritize remediation for externally reachable or widely accessible Pentaho instances, especially where resource names, report structure, or business metadata could reveal sensitive operational context.

Technical view

CVE-2021-45446 is CWE-548 directory listing exposure in Hitachi Vantara Pentaho Business Analytics Server. The Home folder hidden property does not cascade to children, exposing an index of resources. CVSS 3.1 is 5.0: network reachable, low complexity, low privileges required, no user interaction, confidentiality impact only.

Likely exposure

Exposure is most relevant where Pentaho Business Analytics Server is accessible to authenticated users beyond trusted administrators. Internet-facing or broadly shared enterprise deployments increase business risk, but the cited CVSS vector requires low privileges.

Exploitation context

The provided bundle does not establish active exploitation, and the KEV flag is false. The issue is not described as enabling data modification or service disruption; the supported impact is information exposure through resource indexing.

Researcher notes

Evidence supports authenticated directory-index exposure only. Do not assume unauthenticated access, public exploitation, integrity impact, or availability impact from the supplied sources. Vendor advisory should be used for exact fixed builds and operational guidance.

Mitigation direction

  • Upgrade affected Pentaho versions to 9.2.0.2, 8.3.0.25, or later per vendor guidance.
  • Restrict Pentaho access to trusted users until version status is confirmed.
  • Review Home folder resource visibility and remove unnecessary sensitive items.
  • Check the vendor advisory for branch-specific remediation details.

Validation and detection

  • Inventory Pentaho Business Analytics Server deployments and record exact versions.
  • Confirm no deployment is older than 9.2.0.2 or 8.3.0.25 on its branch.
  • Review permissions for Home folder resources and child items.
  • Check application logs for unusual authenticated browsing of hidden resources.
