CVE-2026-37748 affects Visitor Management System 1.0 by sanjay1313. The application is vulnerable to unrestricted file upload in vms/php/admin_user_insert.php and vms/php/update_1.php. In the affected code paths, uploaded files are handled via move_uploaded_file() without effective validation of MIME type, file extension, or file content. Because the application accepts attacker-controlled uploads without restricting executable server-side script types, an authenticated administrator can upload a PHP webshell to a web-accessible location and then invoke it to execute arbitrary commands on the server.

This repository is a small standalone exploit repo containing two files: a README documenting CVE-2026-37748 and a Python exploit script (exploit.py). The exploit targets sanjay1313 Visitor Management System 1.0 and abuses an unrestricted file upload flaw in the admin user creation workflow to achieve remote code execution. The Python script uses requests and argparse, logs into the application with hardcoded default credentials admin/admin at /vms/index.php, uploads a PHP webshell to /vms/php/admin_user_insert.php while spoofing the content type as image/jpeg, and then triggers the shell at /vms/images/shell.php with a cmd query parameter to run arbitrary system commands. The README also identifies vms/php/update_1.php as vulnerable and explains that uploaded files are moved into ../images/ without extension or MIME validation. Overall, this is a real exploit rather than a detector: it provides end-to-end authenticated RCE through file upload and command execution, with a basic hardcoded payload and minimal operator customization via --url and --cmd.
