Technical details
A vulnerability classified as Insufficiently Protected Credentials (CWE-522) exists in the Cluster Test API of Hitachi Vantara Pentaho Data Integration & Analytics. The API returns Hadoop cluster credentials in plain text to the authenticated user. While the vulnerability requires network access and low-level authentication (PR:L), it allows for the disclosure of sensitive authentication material. The risk is partially mitigated by the fact that users with access to this API typically already possess the authority to submit jobs to the backend using the same credentials. The issue is resolved in versions 10.2.0.6 and 11.0.0.0.
