Netty is an asynchronous, event-driven network application framework. Prior to 4.2.13.Final and 4.1.133.Final, Netty's HttpProxyHandler constructs HTTP CONNECT requests with header validation explicitly disabled. The newInitialMessage() method creates headers using DefaultHttpHeadersFactory.headersFactory().withValidation(false), then adds user-provided outboundHeaders without any CRLF validation. This allows an attacker who can influence the outbound headers to inject arbitrary HTTP headers into the CONNECT request sent to the proxy server. This vulnerability is fixed in 4.2.13.Final and 4.1.133.Final.

# Security Vulnerability Report: HTTP Header Injection via HttpProxyHandler Disabled Validation in Netty

## 1. Vulnerability Summary

| Field | Value | |-------|-------| | **Product** | Netty | | **Version** | 4.2.12.Final (and all prior versions) | | **Component** | `io.netty.handler.proxy.HttpProxyHandler` | | **Vulnerability Type** | CWE-113: Improper Neutralization of CRLF Sequences in HTTP Headers | | **Impact** | HTTP Header Injection in CONNECT Proxy Requests | | **CVSS 3.1 Score** | **7.5 (High)** | | **CVSS 3.1 Vector** | `CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N` | | **Related Advisory** | **GHSA-84h7-rjj3-6jx4** (Incomplete Fix) |

## 2. Affected Components

- `io.netty.handler.proxy.HttpProxyHandler` — `newInitialMessage()` method (line 176) explicitly disables header validation via `withValidation(false)`

## 3. Vulnerability Description

Netty's `HttpProxyHandler` constructs HTTP CONNECT requests with **header validation explicitly disabled**. The `newInitialMessage()` method (line 176) creates headers using `DefaultHttpHeadersFactory.headersFactory().withValidation(false)`, then adds user-provided `outboundHeaders` (line 188-190) without any CRLF validation. This allows an attacker who can influence the outbound headers to inject arbitrary HTTP headers into the CONNECT request sent to the proxy server.
