This repository contains a Python exploit script (exploit-cve-2024-26503.py) and a README.md. The exploit targets Open eClass platforms vulnerable to CVE-2024-26503, an unrestricted file upload vulnerability. The script automates the process of authenticating to the platform using provided credentials, uploading a PHP web shell disguised as a badge icon, and then providing an interactive shell for the attacker to execute arbitrary commands on the server via HTTP requests. The script also attempts to clean up by removing the web shell upon exit. The README provides usage instructions, prerequisites, and ethical guidelines. The main exploit logic is contained in the Python script, which interacts with several HTTP endpoints on the target Open eClass instance. The payload is a simple PHP web shell that executes commands passed via the 'cmd' GET parameter. The exploit is operational and provides a working remote code execution capability if the target is vulnerable and valid credentials are supplied.
