## Technical details

An unrestricted file upload vulnerability exists in SourceCodester Simple POS and Inventory System 1.0 within the /admin/addproduct.php component. The 'image' parameter fails to properly validate file extensions, relying on a simple string check that can be bypassed using double extensions or uppercase variations (e.g., .php.jpg). A remote attacker with low-level privileges can exploit this to upload a PHP webshell to the web-accessible /upload/ directory. Additionally, the application is vulnerable to SQL injection in the same endpoint as parameters are concatenated directly into INSERT queries. Successful exploitation allows for Remote Code Execution (RCE) and full database compromise. As of the advisory date, the vulnerability remains unpatched.
