[Mod-security-developers] Proposal on html form protection [Second attempt]

[Carles B. <cbo...@is...>]

Hi Ivan,

Next step in our road-map of improving mod_security is to add some
protection
to html forms. Attached to this mail I've set an initial proposal of our
ideas
of some ways of achieving html forms security. It would be great if you
could
check this ideas out and share your comments/ideas as you kindly did back
when we discussed about cookie management.

We've been also working on a first approach to comment removal. As far=20
as it
goes we're having some issues trying to manage tricky situations where
non-standard markup can fool libxml and so fool our comment stripping cod=
e,
but for the very standard case this new feature is almost coded and teste=
d.

By the way, I would like to congratulate you for the work you've done on
latest 2.0 version. It is really a huge rewrite that has brought so much
clarity and readability to ms code, in addition to all new features and t=
he
ones to come due to brand new ms internal structure.

Last but not least, we expect to be able to port/merge our contributions =
to
2.x branch as soon as I'm back from my holidays and form protection is
coded and
tested.

Best Regards.

PD : Attached documents are text and html version of the proposal. I've
started to use ReStructuredText to write our internal documentation. It
allows
you to write documentation in simple txt with minor and almost invisible
markup (basically the usual space/tab/cr markup used in ordinary text), b=
ut
provides you a set of tools that let you "export"/transform this
"source" text
files to html/latex/pdf. I've found all that very useful because it all l=
et
you focus on important things not losing so much time in writing. It also
allows you to store versioned documentation and access/modify it with
the only
help of a simple text-capable editor. If you're interested, check it out =
