> The AMF deserialization implementation of Flex BlazeDS is vulnerable to Deserialization
of Untrusted Data via {{Externalizable.readExternal(ObjectInput)}}.
> By sending a specially crafted AMF message, it is possible to make the server establish
a connection to an endpoint specified in the message and request an RMI remote object from
that endpoint. This can result in the execution of arbitrary code on the server via Java deserialization.
