Attempted this exploit on Progress Webspeed/OpenEdge 10.1a and received this result:
<!-- Generated by Webspeed: http://www.webspeed.com/ -->
ERROR:
webutil/_cpyfile.r is supported in Development Mode only.
So when the brokers are running in production mode, the exploit will not work.
I assume the exploit runs in development mode but if that is available to the internet that is a bigger problem!
