(Resolved) Pentaho BA Server - Deserialization of Untrusted Data - Versions before 9.4.0.1 and 9.3.0.3 Impacted (CVE-2022-4815)

by Robert Howell - Follow

Overview 

Pentaho Business Analytics Server deserializes untrusted data without sufficiently verifying that the resulting data will be valid. (CWE-502)

 

Products Affected 

Pentaho Business Analytics Server versions before 9.4.0.1 and 9.3.0.3

 

Description 

Pentaho Business Analytics Server versions before 9.4.0.1 and 9.3.0.3 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  

We recommend you upgrade to the Pentaho version 9.5 release or newer. For version 9.4, we recommend updating to Service Pack 9.4.0.1 where this vulnerability is addressed. For version 9.3 we recommend updating to Service Pack 9.3.0.3 or above where this vulnerability is addressed. 

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