没有CSRF保护的HTML表单漏洞解决办法

在Jsp文件头引入

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>

在登录的jsp中添加

<% //增加随机数，解决 CSRF 漏洞
String uuid = UUID.randomUUID().toString().replaceAll("-", "");
request.getSession().setAttribute("randTxt",uuid);
//设置cookie只读
String sessionid = request.getSession().getId();
response.setHeader("SET-COOKIE", "JSESSIONID=" + sessionid + "; secure ; HttpOnly"); %>

form表单中添加一个隐藏域：Input

<input type="hidden" name="randSesion" value = "<%=request.getSession().getAttribute("randTxt")%>" />
