This bug is triggered when the browser handles a JavaScript 'onLoad' handler in conjunction with an improperly initialized 'window()' JavaScript function. This exploit results in a call to an address lower than the heap. The javascript prompt() places the shellcode near where the call operand points to. The module calls prompt() multiple times in separate iframes to place our return address. The module hides the prompts in a popup window behind the main window and then it will spray the heap a second time with the shellcode and point the return address to the heap. It then uses a fairly high address to make this exploit more reliable. IE will crash when the exploit completes. Also, please note that Internet Explorer must allow popups in order to continue exploitation.
