CVE-2021-31599Public exploitNetwork attack vector

Authenticated code execution via embedded BeanShell expressions

Published Nov 8, 2021 · Updated Aug 3, 2024

Code injection in Hitachi Vantara Pentaho Business Analytics Server allows remote authenticated users to execute arbitrary code. Uploaded PRPT report bundles can contain BeanShell expressions whose getValue method the reporting engine evaluates without preventing operating-system command execution. The user must have privileges to upload or edit a report bundle and cause it to run; injected code executes with the Pentaho application user's host permissions.
