AI-analyzed exploit summary This repository contains a functional exploit PoC for CVE-2021-29505, leveraging XStream deserialization with a crafted XML payload to achieve remote code execution via a malicious RMI server. The PoC uses the CommonsCollections6 gadget chain and includes detailed reproduction steps.
Description
XStream is software for serializing Java objects to XML and back again. A vulnerability in XStream versions prior to 1.4.17 may allow a remote attacker has sufficient rights to execute commands of the host only by manipulating the processed input stream. No user who followed the recommendation to setup XStream's security framework with a whitelist limited to the minimal required types is affected. The vulnerability is patched in version 1.4.17.
