Technical details

A chained vulnerability exists in SourceCodester Simple POS and Inventory System 1.0 within /admin/edit_customer.php and /admin/edit_supplier.php. The application fails to sanitize the 'id' GET parameter and various POST parameters before concatenating them into SQL UPDATE statements, leading to SQL injection. Additionally, the application lacks proper authorization checks (IDOR), allowing an authenticated user to modify any record by changing the 'id' parameter. An attacker can exploit this to overwrite the administrator's credentials or extract sensitive data from the database. The vulnerability is currently unpatched, and public exploits are available.
