Class 3 attacks are often met in large corporations where the Web is the
standard way (for both internal employées and "clients") to interact
with the corporate data.

I've seen some webapps audits where :
- malicous data can be inserted via the main corporate website by
anybody with a valid email
- the main processing is done deep in the internal network, through the
Intranet
- the Intranet *must* (corporate policy) be configured as Fully Trusted
in Internet Explorer, allowing the attacker to use, for example,
unsigned ActiveX to hack internal machines.

Not sanitizing input is bad, but storing it for later processing with
different privileges is much worse ...
