CVE-2023-4450 is a critical injection vulnerability in the Template Handler component of jeecgboot JimuReport versions up to 1.6.0. The vulnerability allows remote attackers to manipulate input to the Template Handler, leading to injection attacks. The specific nature of the injection (e.g., SQL, command, or template injection) is not detailed, but the public disclosure and remote exploitability make it a significant risk.

This repository is a weaponized exploit toolkit targeting CVE-2023-4450 in JimuReport, a Java-based reporting platform. The exploit is implemented as a Java application with a GUI (View.java) that automates the exploitation process. The toolkit provides three main capabilities: (1) remote command execution via Freemarker template injection, (2) injection of memory shells (webshells) such as BehinderShell, AntSwordShell, and InceptorMemShell, and (3) persistent backdoor access via these memory shells. The main attack vector is a POST request to the /jmreport/queryFieldBySql endpoint, where malicious Freemarker payloads are injected to achieve code execution or memory shell deployment. The memory shells are implemented as Java classes that hook into the Spring MVC interceptor chain, allowing further command execution or webshell access. The repository is structured as a Maven project with source code in src/main/java, including the main GUI, exploit logic, and memory shell implementations. The exploit is operational and weaponized, providing a user-friendly interface for penetration testers or attackers to exploit vulnerable JimuReport instances.
