【CSRF漏洞-01】跨站请求伪造漏洞靶场实战跨站请求伪造(Cross-site request forgery,CSRF)是一种攻击，它强制终端用户在当前对其进行身份验证后的web应用程序上执行非本意的操作。CSRF攻击的主要目的在伪造更改状态(修改密码、转账等)的请求，而不是盗取数据，因为攻击者无法查看对伪造请求的响应。借助社工的一些帮助(例如通过电子邮件或聊天发送链接)，攻击者可以诱骗用户执行攻击者选择的操作。阅读详情

伪造IP可以使用原始套接字。发送http请求可以参考

这个是最新的,你直接可以调试通,记得在工程/设置->LINK,加WSOCK32.LIB WS2_32.LIB 这两个库!
