AMF3 Java implementations Improper Control of Dynamically-Managed Code Resources

Description

Details reference: https://codewhitesec.blogspot.kr/2017/04/amf.html Some Java implementations of AMF3 deserializers may allow instantiation of arbitrary classes via their public parameter-less constructor and subsequently call arbitrary Java Beans setter methods. The ability to exploit this vulnerability depends on the availability of classes in the class path that make use of deserialization. A remote attacker with the ability to spoof or control information may be able to send serialized Java objects with pre-set properties that result in arbitrary code execution when deserialized. The reporter has identified the following products and versions as being affected, and CVE IDS have been assigned as follows: \- Flamingo amf-serializer by Exadel, version 2.2.0 - CVE-2017-3202 \- Flex BlazeDS , versions 4.6.0.23207 and 4.7.2 - CVE-2017-5641 \- GraniteDS, version 3.1.1. GA - CVE-2017-3200 Products using these libraries may also be impacted.
