gitlab/maven/org.springframework.flex/spring-flex/CVE-2017-3203
Deserialization of Untrusted Data
The Java implementations of AMF3 deserializers in Pivotal/Spring Spring-flex derive class instances from `java.io.Externalizable` rather than the AMF3 specification's recommendation of `flash.utils.IExternalizable`. A remote attacker with the ability to spoof or control an RMI server connection may be able to send serialized Java objects that execute arbitrary code when deserialized.
