CVE-2022-24801— Twisted 环境问题漏洞

HTTP Request Smuggling in twisted.web

Twisted is an event-based framework for internet applications, supporting Python 3.6+. Prior to version 22.4.0rc1, the Twisted Web HTTP 1.1 server, located in the `twisted.web.http` module, parsed several HTTP request constructs more leniently than permitted by RFC 7230. This non-conformant parsing can lead to desync if requests pass through multiple HTTP parsers, potentially resulting in HTTP request smuggling. Users who may be affected use Twisted Web's HTTP 1.1 server and/or proxy and also pass requests through a different HTTP server and/or proxy. The Twisted Web client is not affected. The HTTP 2.0 server uses a different parser, so it is not affected. The issue has been addressed in Twisted 22.4.0rc1. Two workarounds are available: Ensure any vulnerabilities in upstream proxies have been addressed, such as by upgrading them; or filter malformed requests by other means, such as configuration of an upstream proxy.

HTTP请求的解释不一致性(HTTP请求私运)

Twisted 环境问题漏洞

Twisted是一款使用Python语言编写的事件驱动的开源网络引擎。 Twisted 存在环境问题漏洞，该漏洞源于在版本22.4.0rc1之前，Twisted Web HTTP 1.1服务器位于Twisted中。网状物http模块，比RFC 7230允许的更轻松地解析了几个http请求构造。如果请求通过多个HTTP解析器，这种不一致的解析可能会导致去同步，从而可能导致HTTP请求走私。
