(Resolved) Pentaho BA Server - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') - Versions before 9.4.0.0 and 9.3.0.1, including 8.3.x Impacted (CVE-2022-43771)

Overview 

Hitachi Vantara Pentaho Business Analytics Serveruses 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. (CWE-22)

 

Products Affected 

Hitachi Vantara Pentaho Business Analytics Server versions before 9.4.0.0 and 9.3.0.1, including 8.3.x are impacted.

 

Description 

Hitachi Vantara Pentaho Business Analytics Server versions before 9.4.0.0 and 9.3.0.1, including 8.3.x, using the Pentaho Data Access plugin exposes a service endpoint for CSV import which allows a user supplied path to access resources that are out of bounds.

 

Impact 

Many file operations are intended to take place within a 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.

 

Action  

We recommend you upgrade to the latest Hitachi Vantara Pentaho version 9.4 release. For version 9.3 we recommend updating to Service Packs 9.3.0.1 or above where this vulnerability is addressed. 

Please review the Pentaho End-of-Life policy to ensure you are up to date.
