Microsoft Internet Explorer 8 and 9, when the Proxy Settings configuration has the same Proxy address and Port values in the HTTP and Secure rows, does not properly reuse TCP sessions to the proxy server, which allows remote attackers to obtain sensitive information intended for a specific host via a crafted HTML document that triggers many HTTPS requests and then triggers an HTTP request to that host, as demonstrated by reading a Cookie header, aka MSRC 12096gd.

Microsoft Internet Explorer 配置错误漏洞

Microsoft Internet Explorer是美国微软（Microsoft）公司发布的Windows操作系统中默认捆绑的Web浏览器。 Microsoft Internet Explorer 8和9版本中存在漏洞，该漏洞源于在代理配置的HTTP和安全行中具有同样的代理地址和端口值的情况下，程序没有正确地对代理服务器重用TCP会话。通过特制的HTML文档触发向任意主机发送多个HTTPS请求，随后再向某可信主机发送一个HTTPS请求且向某不可信主机发送一个HTTP请求（如读取Cookie头文件），远
