Exploit is ready, i thought make it more powerfull - download some stuff from internet, launch it (it will do some things like copy some valuable files from your computer to zip archive on your desktop, to demonstrate a level of danger of this issue), but i rejected this, because i will publish these sources and i dont want someone will use this "with a light hand" (ready to use and working thing for bad things).
Exploit change your desktop wallpaper to black screen, i think this is enought for demonstration.
I begin work on patch for PX. I don't think it will be included in official bundle (but i hope), I will make it as an extension of wkPX module for now (wormkit module file that will fix problems in PX).
After that work done i will publush exploit code and details about it.
(Busy at work, may delay with the release
stay tuned
