This repository provides a working exploit for CVE-2020-11984, targeting Apache HTTP Server with mod_proxy_uwsgi and a backend uWSGI server. The exploit (exploit.py) is a Python script that crafts a malicious uWSGI request, leveraging the 'exec://' functionality to achieve remote command execution (RCE) on the target server. The Dockerfile sets up a vulnerable environment with Apache 2.4.32 and uWSGI, exposing the uWSGI service on 127.0.0.1:8080 and proxying requests from Apache. The README provides usage instructions, including how to build and run the vulnerable environment and how to launch the exploit. The main attack vector is network-based, requiring access to the uWSGI service. The exploit is operational, allowing arbitrary shell command execution on the target. Notable endpoints include the uWSGI service at 127.0.0.1:8080 and example file paths used in the exploit. The repository is structured with setup files (Dockerfile, supervisord.conf), the exploit script (exploit.py), and a simple WSGI application (upstream.py) for demonstration.
