#Description
############        

cPanel & WebHost Manager (WHM) is a next generation web hosting control 
panel system. Both cPanel & WHM are extremely feature rich as well as 
include an easy to use web based interface.

#Vulnerability

After some looking into, I found out that cPanel uses little or no html filters
in their product. It's very simple to inject html in multiple areas in cpanel. 
I'll list the ones I've found so far.

Note: Those should appear as < script > and < /script > with out the spaces of course.
