We are putting our new Craft CMS 3.2 install (dev environment) through some security scan paces, including uploads of 500Mb files. We'd expect to throw an exception message/error page on an over-the-limit file, but it is not doing that currently (it simply hangs).
When we run these scans against other CMS applications, when the upload is attempted, an error is thrown by the web server and the underlying CMS applications continue to function as they should as do the actual scans. This is not the case when it comes to Craft.
To pass the security scan, we'd like Craft to throw an error, not just 'hang.'
If Craft is hanging or timing out while you’re uploading a large file, or if you get the error message “The uploaded file is empty”, you’re probably running into a limitation imposed by your server’s configuration. https://craftcms.com/guides/troubleshooting-unsuccessful-file-uploads
