IncrediMail 5.86 Cross Site Scripting Vulnerabilit

`#!/usr/bin/perl -w  
  
# 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.
