There is nothing wrong with your example
>printf "%s", "long string with $user supplied values";

is a perfectly legal Perl statement. That is the problem with Perl, there are too many different ways to do the same thing in Perl. That is not flexibility, it is poor design.

Webmin is not doing anything wrong and so the flaw is not in Webmin, it is an error in Perl.

I'd have to agree that it would be difficult to take advantage of this bug in order to compromise a system and that I would need to see a working example before I'd raise any red flags.
