## Technical details

The vulnerability exists in the Environment Variable Handler within app/Http/Controllers/SettingsController.php. The application fails to sanitize user input (specifically newline characters) when updating system configurations, allowing an authenticated attacker to inject arbitrary variables into the .env file. By overriding the DUMP_PATH variable, an attacker can redirect the path used by the DatabaseBackUp command. When a backup is triggered, the application executes the attacker-controlled path via PHP's exec() function, leading to Remote Code Execution (RCE) with the privileges of the web server.
