Loading vulnerability…
CVE-2025-5840 is a critical unrestricted file upload vulnerability in SourceCodester Client Database Management System 1.0. The issue affects an unknown code path in /user_update_customer_order.php, where the uploaded_file argument can be manipulated to upload files without proper restriction or validation. Based on the available information, the application does not adequately enforce controls on uploaded content, allowing a remote attacker to submit arbitrary files to the server.

This repository contains a Python exploit script (CVE-2025-5840.py) and a README file. The exploit targets a file upload vulnerability in a web application endpoint '/cdm/user_update_customer_order.php'. It attempts to upload a PHP webshell (default name 'shell.php') to the server by sending a POST request with a crafted file. If successful, the webshell is expected to be accessible at '/cdm/files/shell.php' (or a user-specified filename). The script saves the HTTP response to 'response.txt' for further inspection. The README provides usage instructions and cautions that the exploit is for educational purposes only. No detection or fake code is present; the exploit is operational and provides a working webshell payload for remote command execution.
