Vulnerability Details:
Pentaho implements a series of web services using the SOAP protocol to allow scripting interaction with the backend server. HAWSEC identified that the services userRoleListService and ServiceAction exposed through the "/pentaho/webservices/userRoleListService" and "/pentaho/ServiceAction?action=SecurityDetails" endpoints are not enforcing sufficient access controls. Specifically, an authenticated user can list all application usernames present in the Jackrabbit Repository.
