Authenticated unauthorized actions via JSON gadget chains
Published May 24, 2023 · Updated Jan 16, 2025
Untrusted deserialization in Pentaho Business Analytics Server allows remote authenticated users to perform unauthorized actions. The JSON parser accepts attacker-chosen classes and methods instead of restricting them to an approved set, enabling gadget chains to self-execute during deserialization. Exploitation requires low-privileged access and user interaction; vendor materials do not identify the endpoint or bound the unauthorized actions further.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=1.0 <9.3.0.3
- Affected versionversion=9.4.0.0 <9.4.0.1
