AppSec Europe 2018

XSS is about twenty years old by now and appears to be alive and
kicking. JavaScript alerts are still popping left and right and bug
bounty programs are drowning in submissions.

But is XSS really still a problem of our time? Or is it just an undead
foul-smelling zombie vulnerability from the dark ages of string
concatenation that doesn't wanna perish because we are just too fricken
stubborn?

This talk will be an hour-long rant (yes, swearwords, leave your kids at
home), paired with a stroll through the history of XSS and related
issues. We will go back into the year 1998 and see how it all started,
how things developed, what we tried to do against it and how hard we
failed every single time. We will also look at the future and predict
what is about to happen next. Mostly nothing - but good to know, right?

We will not only look at our own failures but also see how the entire
infrastructure and monetization of the web contributed to us being
simply not capable or even just willing to fix XSS. And we might as well
see if any of those behavioral and structural patterns can be compared
to other human failures - and see if there is something we all can
learn. Or, at least, agree that we knew it all along and are all on the
same page.
