(Resolved) Pentaho BA Server - Use of Non-Canonical URL Paths for Authorization Decisions - Versions before 9.4.0.1 and 9.3.0.2, including 8.3.x Impacted (CVE-2022-43939)

by Dan Begey - Follow

Overview 

The software defines policy namespaces and makes authorization decisions based on the assumption that a URL is canonical. This can allow a non-canonical URL to bypass the authorization. (CWE-647) 

 

Products Affected 

Hitachi Vantara Pentaho Business Analytics Server versions before 9.4.0.1 and 9.3.0.2 impacted.

 

Description 

Hitachi Vantara Pentaho Business Analytics Server versions before 9.4.0.1 and 9.3.0.2, including 8.3.x contain security restrictions using non-canonical URLs which can be circumvented. 

 

Impact 

If an application defines policy namespaces and makes authorization decisions based on the URL, but it does not require or convert to a canonical URL before making the authorization decision, then it opens the application to attack. 

 

Action  

The defect may be mitigated now by defining a more restrictive set of authorization filters in the security configuration of the product.  

We recommend you upgrade to Hitachi Vantara Pentaho Business Analytics Server version 9.3 (Long Term Support Release) with 9.3.0.2 or newer applied, or the latest 9.4 release with 9.4.0.1 or newer. 

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