AI-analyzed exploit summary This repository contains a functional exploit PoC for CVE-2021-39141, demonstrating deserialization vulnerabilities in XStream 1.4.17. The code includes a server setup to handle HTTP requests and a demo showcasing the exploitation via crafted XML payloads.

XStream is a simple library to serialize objects to XML and back again. In affected versions this vulnerability may allow a remote attacker to load and execute arbitrary code from a remote host only by manipulating the processed input stream. No user is affected, who followed the recommendation to setup XStream's security framework with a whitelist limited to the minimal required types. XStream 1.4.18 uses no longer a blacklist by default, since it cannot be secured for general purpose.
