Just people who have admin access to Interchange, or enough access to be
able to inject ITL somewhere.  Keep in mind that if someone can find a
code injection vulnerability on one of your pages then this can be used
to greatly increase what they can see and do.  Basically it allows a
user to bypass the NoAbsolute global configuration directive.  Also this
vulnerability allows write as well as read access to any files that the
interch user can write.
