In Jboss Application Server as shipped with Red Hat Enterprise Application Platform 5.2, it was found that the doFilter method in the ReadOnlyAccessFilter of the HTTP Invoker does not restrict classes for which it performs deserialization and thus allowing an attacker to execute arbitrary code via crafted serialized data.

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.
