Nice summary.

I can add to the list of attack vectors a case where the WAF introduced a reflected cross-site scripting vulnerability. The site it was supposedly protecting was blank, i.e. it just returned a 404 error or something. But just by appending a URL parameter with JS in it, the WAF would trigger and reflect the code. So I was able to build an outlook web app lookalike for phishing on a site with the domain of the company.
