## Technical details

A Remote Code Execution (RCE) vulnerability exists in SourceCodester Multi-Vendor Online Grocery Management System 1.0 within the `update_settings_info` function of `classes/SystemSettings.php`. The application accepts a POST array `content[]` and uses its keys and values to write files to disk via `file_put_contents()` without sanitization. By supplying a key such as 'welcome', an attacker can overwrite `welcome.html` with a PHP payload. Because `home.php` uses `include()` to load this file, the injected PHP code is executed upon visiting the home page. This vulnerability requires low-level authentication but can be chained with other flaws to achieve unauthenticated RCE. No official patch is currently available.
