Loading vulnerability…
CVE-2024-38816 is a path traversal vulnerability in Spring Framework functional web applications using WebMvc.fn or WebFlux.fn to serve static resources. The flaw applies where RouterFunctions-based resource handling is explicitly configured with a FileSystemResource location. Insufficient path validation permits crafted HTTP requests containing traversal sequences to resolve files outside the intended static-resource directory.

This repository is a proof-of-concept (PoC) exploit for CVE-2024-38816, a path traversal vulnerability in Spring Framework (prior to 6.1.13) when using RouterFunctions and FileSystemResource to serve static files. The repository contains a minimal Java Spring Boot application (PathTraversalDemoApplication.java) that exposes static files from /app/static/ via the /static/** route. The Dockerfile sets up the environment, creates the necessary directories, and establishes a symbolic link (/app/static/link -> /static) to facilitate the exploit. The README provides detailed steps to build and run the application in Docker, and demonstrates the exploit using a crafted HTTP request to http://localhost:8080/static/link/%2e%2e/etc/passwd, which, if successful, returns the contents of /etc/passwd, confirming the vulnerability. The exploit leverages percent-encoded directory traversal (.. as %2e%2e) through a symbolic link to bypass path restrictions. The repository is structured as a simple PoC for educational and research purposes, and does not include weaponized or automated exploitation features.
