Spring4Shell-POC is a dockerized application that is vulnerable to the Spring4Shell vulnerability (CVE-2022-22965). Full Java source for the war is provided and modifiable, the war will get re-built whenever the docker image is built. The built WAR will then be loaded by Tomcat. There is nothing special about this application, it’s a simple hello world that’s based off Spring tutorials.

Docker
Python3 + requests library

Clone the repository
Build and run the container: docker build . -t spring4shell && docker run -p 8080:8080 spring4shell
