Associated Vulnerability

Title:Spring Framework 代码注入漏洞 (CVE-2022-22965)
Description:A Spring MVC or Spring WebFlux application running on JDK 9+ may be vulnerable to remote code execution (RCE) via data binding. The specific exploit requires the application to run on Tomcat as a WAR deployment. If the application is deployed as a Spring Boot executable jar, i.e. the default, it is not vulnerable to the exploit. However, the nature of the vulnerability is more general, and there may be other ways to exploit it.

## Blog post
A more detailed analysis and explanation of the vulnerability can be found on my [blog post](https://medium.com/@cxzero/spring4shell-cve-2022-22965-vulnerability-analysis-and-exploitation-fae244dfd3eb).

## Comments on initial research
Based on the initial research I did on https://github.com/GuayoyoCyber/CVE-2022-22965 with these additions:
- modifications on HelloWorld class and helloworld.jsp for a better understanding of the vulnerability 
- added Apache Tomcat 9.0.60 embed library dependency for debugging purposes

## Compilation
```
sudo apt install maven
mvn clean package
```
Apache Tomcat 9.0.60 can be downloaded from https://archive.apache.org/dist/tomcat/tomcat-9/v9.0.60/bin/apache-tomcat-9.0.60.zip

Smart Tomcat IntelliJ plugin can be used to speed up running and debugging: https://plugins.jetbrains.com/plugin/9492-smart-tomcat

## Docker
```
sudo docker build -t spring4shell .
```
or
```
sudo docker build -t spring4shell -f Dockerfile2 .
```
```
sudo docker run -p 8082:8080 spring4shell
```
