CVE-2017-3202

CVE-2017-3202 describes a critical deserialization vulnerability in Exadel's Flamingo amf-serializer, version 2.2.0, specifically within its Java AMF3 deserializers. This flaw allows remote attackers to instantiate arbitrary classes and invoke setter methods, potentially leading to arbitrary code execution if suitable classes are present on the classpath. With a CVSS score of 9.8 (Critical), it presents a high-impact, low-complexity attack vector requiring no user interaction or privileges. Despite its severity, there is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
