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.

Description

In this challenge, I analyzed the Spring4Shell (CVE-2022-22965) vulnerability, investigated security bypasses, and wrote an Incident Postmortem Report detailing the detection, impact, and resolution of the attack. I also implemented a firewall rule in Python to block malicious requests and prevent future exploitation.
