Has anyone constructed this exploit as a simple `wget` command?



wget --header='Referer: () { :;}; touch /tmp/vulnerable ' www.example.com


Note that you'll typically want to supply the URL to a CGI script on the site, not just www.example.com. Don't think you're unaffected just because the top-level page of your site doesn't appear vulnerable.


Is there some easy way of detecting a site you don't control is vulnerable without bringing it down?


Yes, you can ask it to ping an address you control and record where the pings come from.
