  Indeed. I certainly wasn't claiming any greatness on the part of the
program, especially since we're not a Window's shop -- it doesn't
particularly apply to me. My point was that while I may be comfortable
with using Perl/LWP and regular expressions as a coder, these are things
I use on a regular basis while doing assessments.  However, for others
(such as many who I work with that do not code) this provides a simple
way to demonstrate various simple client-side state weaknesses.

  I would also agree that there are many other tools out there that do
similar things (and much more.) Especially where actual assessments are
the goal.  I was just simply stating that for its intended purpose, it
works, and integrates into IE as a side bar making it easy to tote
around. (Again, For those who use IE...  )

No doubt it looks slick. I've not attempted to run it (don't really have any
need nor desire to). Though for desktop use, sure this would be a better
solution. I'm not sure what you mean by "those who use LWP and regex"
though? LWP is a Perl module and regex is short for "regular expression".
I.e., s/<input[\s\n]+type\s*=[\s\n]*hidden[\s]+/<input type=text/igs; It
would automatically transform hidden tags to text fields for every page. It
would operate and look the same and any things that require a referer could
be easily modified to work.

I.e. surf with hidden tags shown as text fields. The script's wouldn't and
couldn't know the difference. In other words, you could put it on a web site
(or tun it locally--yes, if you had Perl and the LWP module installed
locally) and surf such as that. Anyway, it's a trivial matter anyway. If a
script is vulnerable to such things, it's pretty much a target that will get
hit anyway. I suppose this tool, or the Perl solution (this would be about 4
lines or so of code, is why I mentioned it) would provide a bored person
with a few minutes of fun. :-)
