CVE-2017-3203
Pivotal/Spring Spring-flex's Action Message Format (AMF3) Java implementation is vulnerable to insecure deserialization
HIGH 8.1EPSS 6.2%
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.
