Incorrect authorization in affected IBM Jazz Foundation 7.x releases allows remote attackers to alter server property files. The open RegistrationHandlerService accepts unauthenticated property changes when its teamserver.properties setting is true. The service must be open; successful changes permit unauthorized actions and can interrupt the server through denial of service.
