component provides a convenient method of remotely accessing Seam
It was found that the ExecutionHandler, PollHandler, and
SubscriptionHandler classes in JBoss Seam Remoting unmarshalled
user-supplied XML and resolved external entities in this XML. A remote
attacker could use this flaw to read files accessible to the user running
the application server, and potentially perform other more advanced XML
External Entity (XXE) attacks. (CVE-2013-6447)
It was found that the InterfaceGenerator handler in JBoss Seam Remoting
exposed details of all classes and methods on the server's classpath, not
only methods with the org.jboss.seam.annotations.remoting.WebRemote
annotation. A remote attacker could use this flaw to determine which
classes are deployed on the JBoss server. (CVE-2013-6448)
