Overview 

The application deserializes untrusted data without sufficiently verifying that the resulting data will be valid. (CWE-502)

 

Products Affected 

Hitachi Vantara Pentaho Business Analytics Server versions before 10.2.0.0 and 9.3.0.9, including 8.3.x

 

Description 

Hitachi Vantara Pentaho Business Analytics Server versions before 10.2.0.0 and 9.3.0.9, including 8.3.x, deserialize untrusted JSON data without constraining the parser to approved classes and methods.

 

Impact 

When developers place no restrictions on "gadget chains," or series of instances and method invocations that can self-execute during the deserialization process (i.e., before the object is returned to the caller), it is sometimes possible for attackers to leverage them to perform unauthorized actions.

 

Action  

The defect may be mitigated now by removing the Pentaho Interactive Reporting plugin from the software installation.

We recommend you upgrade to the latest Hitachi Vantara Pentaho 10.2 release where this vulnerability is addressed. For version 9.3, we recommend installing Service Pack 9.3.0.9 or higher where this vulnerability is addressed. 

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