会话cookie中缺少HttpOnly属性

项目经第三方机构进行安全扫描漏洞出现“会话cookie中缺少HttpOnly属性”问题

安全风险

可能会窃取或操纵客户会话和 cookie，它们可能用于模仿合法用户，从而使黑客能够以该用户身份查看或变更用户记录以及执行事务

可能原因

Web 应用程序设置了缺少 HttpOnly 属性的会话 cookie

技术描述

在应用程序测试过程中，检测到所测试的 Web 应用程序设置了不含“HttpOnly”属性的会话 cookie。由于此会话 cookie 不包含“HttpOnly”属性，因此注入站点的恶意脚本可能访问此 cookie，并窃取它的值。任何存储在会话令牌中的信息都可能被窃取，并在稍后用于身份盗窃或用户伪装。

解决方法加入一个拦截器即可：

package com.base.servlet;

import java.io.IOException;

import java.text.SimpleDateFormat;

import java.util.Calendar;
import java.util.Date;
import java.util.Locale;

import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.Cookie;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

/**
* 解决检测到会话 cookie 中缺少 HttpOnly 属性
*
*/
public class CookieHttpOnlyFilter implements Filter {
public void destroy() {
}

public void doFilter(ServletRequest request, ServletResponse response,
FilterChain filterChain) throws IOException, ServletException {
// TODO Auto-generated method stub
HttpServletRequest req = (HttpServletRequest) request;
HttpServletResponse resp = (HttpServletResponse) response;
Cookie[] cookies = req.getCookies();

if (cookies != null) {
for (Cookie cookie : cookies) {
String value = cookie.getValue();
StringBuilder builder = new StringBuilder();
builder.append("JSESSIONID=" + value + "; ");
builder.append("Secure; ");
builder.append("HttpOnly; ");

Calendar cal = Calendar.getInstance();
cal.add(Calendar.HOUR, 1);

Date date = cal.getTime();
Locale locale = Locale.CHINA;
SimpleDateFormat sdf = new SimpleDateFormat("dd-MM-yyyy HH:mm:ss",
locale);
builder.append("Expires=" + sdf.format(date));
resp.setHeader("Set-Cookie", builder.toString());
}

filterChain.doFilter(request, response);
}
}

public void init(FilterConfig arg0) throws ServletException {
// TODO Auto-generated method stub
}
}

然后在配置文件web.xml中进行配置

<filter>
<filter-name>cookieHttpOnlyFilter</filter-name>
<filter-class>com.base.servlet.CookieHttpOnlyFilter</filter-class>
</filter>

<filter-mapping>
<filter-name>cookieHttpOnlyFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
