Insufficient Protection against HTTP Request Smuggling in mitmproxy

mitmproxy is an interactive, SSL/TLS-capable intercepting proxy. In mitmproxy 7.0.4 and below, a malicious client or server is able to perform HTTP request smuggling attacks through mitmproxy. This means that a malicious client/server could smuggle a request/response through mitmproxy as part of another request/response's HTTP message body. While mitmproxy would only see one request, the target server would see multiple requests. A smuggled request is still captured as part of another request's body, but it does not appear in the request list and does not go through the usual mitmproxy event hooks, where users may have implemented custom access control checks or input sanitization. Unless mitmproxy is used to protect an HTTP/1 service, no action is required. The vulnerability has been fixed in mitmproxy 8.0.0 and above. There are currently no known workarounds.

mitmproxy 环境问题漏洞

mitmproxy是一个交互式的、支持 SSL/TLS 的拦截代理，带有用于 HTTP/1、HTTP/2 和 WebSockets 的控制台界面。 mitmproxy 7.0.4 版本及之前版本存在安全漏洞，该漏洞源于恶意客户端或服务器能够通过 mitmproxy 执行请求夹带（request smuggling）攻击。
