Inconsistent Interpretation of HTTP Requests in twisted.web

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: 1. The Content-Length header value could have a + or - prefix. 2. Illegal characters were permitted in chunked extensions, such as the LF \n...

Http-Desync-Guardian - Analyze HTTP Requests To Minimize Risks Of HTTP Desync Attacks (Precursor For HTTP Request Smuggling/Splitting)

Overview HTTP/1.1 went through a long evolution since 1991 to 2014: HTTP/0.9 – 1991 HTTP/1.0 – 1996 HTTP/1.1 RFC 2068 – 1997 RFC 2616 - 1999 RFC 7230 - 2014 This means there is a variety of servers and clients, which might have different views on request boundaries, creating opportunities for...

HTTP Request Smuggling in hyper

Summary hyper's HTTP server code had a flaw that incorrectly understands some requests with multiple transfer-encoding headers to have a chunked payload, when it should have been rejected as illegal. This combined with an upstream HTTP proxy that understands the request payload boundary different...

GHSA-5H46-H7HH-C6X9 Integer Overflow in Chunked Transfer-Encoding

Summary hyper's HTTP server and client code had a flaw that could trigger an integer overflow when decoding chunk sizes that are too big. This allows possible data loss, or if combined with an upstream HTTP proxy that allows chunk sizes larger than hyper does, can result in "request smuggling" or...
