CVE-2023-38697 protocol-http1 HTTP Request/Response Smuggling vulnerability

protocol-http1 provides a low-level implementation of the HTTP/1 protocol. RFC 9112 Section 7.1 defined the format of chunk size, chunk data and chunk extension. The value of Content-Length header should be a string of 0-9 digits, the chunk size should be a string of hex digits and should split...

CVE-2023-38697

The CVE-2023-38697 entry concerns protocol-http1 (HTTP/1) parsing: Falcon’s RFC-compliant checks on Content-Length and chunk size can be bypassed by accepting +, 0x prefixes, and LF in chunk extensions, causing desynchronization across HTTP parsers and enabling HTTP request smuggling or firewall ...

HTTP Request Smuggling

Overview Affected versions of this package are vulnerable to HTTP Request Smuggling due to improper RFC implementation. This behavior can lead to desync when forwarding through multiple HTTP parsers, potentially resulting in HTTP request smuggling and firewall bypassing. Remediation Upgrade...

Parser creates invalid uninitialized value

Affected versions of this crate called mem::uninitialized in the HTTP1 parser to create values of type httparse::Header from the httparse crate. This is unsound, since Header contains references and thus must be non-null. The flaw was corrected by avoiding the use of mem::uninitialized, using...

netty: Request smuggling via content-length header

A flaw was found in Netty. There is an issue where the content-length header is not validated correctly if the request uses a single Http2HeaderFrame with the endstream set to true. This flaw leads to request smuggling if the request is proxied to a remote peer and translated to HTTP/1.1. The...

netty: possible request smuggling in HTTP/2 due missing validation

In Netty io.netty:netty-codec-http2 before version 4.1.60.Final there is a vulnerability that enables request smuggling. If a Content-Length header is present in the original HTTP/2 request, the field is not validated by Http2MultiplexHandler as it is propagated up. This is fine as long as the...
