CVE-2023-1826Public exploitNetwork attack vector

Authenticated code execution via unrestricted PHP upload

Published Apr 4, 2023 · Updated Feb 11, 2025

Unrestricted file upload in Medicine Tracker System Project Online Computer and Laptop Store 1.0 allows remote authenticated users to execute code. The admin/system_info/index.php endpoint processes the img upload without restricting dangerous file types, so a PHP shell is stored for web execution. Access to the administrative endpoint is required; successful exploitation runs attacker-supplied PHP in the web server's security context.
