Loading vulnerability…
CVE-2024-31777 is a file upload vulnerability affecting Open eClass version 3.15 and earlier. The issue is present in the certbadge.php endpoint, which can be abused by supplying a crafted file upload. Insufficient validation or restriction of uploaded file content allows an attacker to upload a malicious file that is subsequently executed by the server, resulting in arbitrary code execution.

This repository provides a proof-of-concept exploit for CVE-2024-31777, a critical unrestricted file upload vulnerability in the GUnet OpenEclass E-learning platform. The exploit is implemented in Python (CVE-2024-31777.py) and requires administrator credentials to authenticate to the target system. The script logs in, creates a ZIP archive containing a simple PHP web shell, and uploads it via the vulnerable 'certbadge.php' endpoint. Once uploaded, the script allows the attacker to interactively execute arbitrary system commands on the server through the web shell by sending requests to the uploaded PHP file. The repository also includes a README.md with usage instructions and a requirements.txt listing dependencies. The exploit demonstrates remote code execution via a network attack vector, targeting authenticated admin users of OpenEclass installations prior to the vendor's hotfix for version 3.16. No hardcoded IPs or domains are present; the base URL is supplied by the user at runtime.
