Remediation
Red Hat mitigation
Setting enabledForExtensions is false by default, thus <ex:serializable> elements are not automatically deserialized. However, if you have it enabled and you don't need any of the provided functions (https://ws.apache.org/xmlrpc/extensions.html) we suggest you disable it.
