I've installed the latest version of DNN (8.0.4.226) and when I place module (zips) in the Install\modules folder and try to go here:
"http://localhostdnnsite/install/install.aspx?mode=InstallResources"
I get a 404. I, too, thought this had to do with the security vulnerabilities\issues that were found in the past, but it sounds like it should be working? What am I doing wrong?
