An attacker may be able to reproduce the following steps: - Install a package with a web Laravel application. - Navigate to the Upload window - Upload an image file, then capture the request - Edit the request contents with a malicious file (webshell) - Enter the path of file uploaded on URL - Remote Code Execution **Note: Prevention for bad extensions can be done by using a whitelist in the config file(lfm.php).
