Apache Struts is an open-source web application framework for developing Java EE web applications. It uses and extends the Java Servlet API to encourage developers to adopt a model-view-controller (MVC) architecture.
The REST plugin in Apache Struts uses **XStreamHandler**
with an instance of XStream for deserialization without any type filtering, allowing a remote, unauthenticated attacker to execute arbitrary commands.
Upgrade to Apache Struts 2.3.34 or 2.5.13 or higher.
