Red Hat Security Advisory 2015-0862-01 – Red Hat JBoss Operations Network is a middleware management solution that provides a single point of control to deploy, manage, and monitor JBoss Enterprise Middleware, applications, and services. It was discovered that the JBoss Operations Network server did not correctly restrict access to certain remote APIs. A remote, unauthenticated attacker could use this flaw to execute arbitrary Java methods via ServerInvokerServlet or SchedulerService, and possibly exhaust all available disk space via ContentManager.
