A flaw was discovered in the Apache XML-RPC (ws-xmlrpc) library that deserializes untrusted data when enabledForExtensions setting is enabled. A remote attacker could use this vulnerability to execute arbitrary code via a crafted serialized Java object in a <ex:serializable> element.

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.
