When we want to use a CSRF vulnerability to attack, we usually load the vulnerability CSRF interface on a third-party site using resource requests, when users access this page, they will secretly send an http request to the vulnerability site, that is, the attack is successful. Instance exploitation code: There are many ways to send http requests using resources. attributes with authentication information

cookie，并发送到a.php，用户的cookie已经就会到攻击者的服务器上。攻击者利用浏览器插件，将自己的cookie替换成刚刚获取的用户的cookie，就可以狸猫换太子的冒充用户了。防御原理说清楚了，再来谈谈如何防御吧。最基本的防御就是对用户的输入进行转义，例如如果直接保存这个字符串的话，然后再输出的话，就会运行JS了。我们需要将这个字符串转义成"有些语言自带的就有一些函数来实现转义的功能。比如php中，提供了 htmlspecialchars() 函数可以将HTML 特殊字符转化成在网页上显示的字符实体编码。这样即使用户输入了各种HTML 标记，在读回到浏览器时，会直接显示这些HTML 标记，而不是解释执行。这里举一个例子：攻击者输入：结果为：分析可以得知，在HTML 正文背景下，其中ENT_NOQUOTES的意思是不对单引号和双引号进行编码。而其他语言，比如.net，则有微软提供的类库AntiXSS，它的实现原理是白名单机制。使用起来也很简单，就是通过AntiXss.GetSafeHtmlFragment(html)方法，来替换掉html里的危险字符。代码如下：
