Description

A flaw was found in JBoss Enterprise Application Platform. The `processInvocation` function within the `org.jboss.as.ejb3.security.AuthorizationInterceptor` component incorrectly authorizes all requests when no roles are defined for an Enterprise Java Beans (EJB) method invocation. This allows attackers to bypass intended access restrictions for EJB methods, leading to unauthorized access to sensitive functionalities.
