Pentaho allows users to create and manage Data Sources. Users can select a Data Source when creating a Dashboard through the Pentaho User Console. When a Data Source is added, Pentaho makes a HTTP request to the dashboards editor (/pentaho/api/repos/dashboards/editor) in order to test the connection by executing a test SQL query. However, further examination revealed that by utilizing CVE-2021-31602, an authentication bypass of Spring APIs, it is possible for an unauthenticated user to execute arbitrary SQL queries on any Pentaho datasource and thus retrieve data from the related databases.

Pentaho allows users to upload various files of different file types. The upload service is implemented under the /pentaho/UploadService endpoint. The file types allowed by the application are csv, dat, txt, tar, zip, tgz, gz, gzip. When uploading a file with an extension other than the allowed file types, the application responds with the error message of UploadFileServlet.ERROR_0011 - File type not allowed. Allowable types are csv,dat,txt,tar,zip,tgz,gz,gzip. However, the file extension check can be bypassed by including a single dot "." at the end of the filename.
