Descriptions

An issue was discovered in Hitachi Vantara Pentaho through 9.1 and Pentaho Business Intelligence Server through 7.x. A reports (.prpt) file allows the inclusion of BeanShell scripts to ease the production of complex reports. An authenticated user can run arbitrary code.

Se ha detectado un problema en Hitachi Vantara Pentaho versiones hasta 9.1 y en Pentaho Business Intelligence Server versiones hasta 7.x. Un archivo de informes (.prpt) permite una inclusión de scripts BeanShell para facilitar la producción de informes complejos. Un usuario autenticado puede ejecutar código arbitrario

Pentaho allows users to create and run Pentaho Report Bundles (.prpt). Users can create PRPT reports by utilizing the Pentaho Designer application and can include BeanShell Script functions to ease the production of complex reports. However, the BeanShell Script functions can allow for the execution of arbitrary Java code when Pentaho PRPT Reports are run by Pentaho Business Analytics. This functionality allows any user with sufficient privileges to upload or edit an existing Pentaho Report Bundle (through Pentaho Designer) and execute arbitrary code in the context of the Pentaho application user running on the web server.
