Netty: STOMP CONNECT Frame Header Injection
Vulnerability Description
Netty is an asynchronous, event-driven network application framework. In versions prior to 4.1.136.Final and 4.2.16.Final, Netty's STOMP encoder ( StompSubframeEncoder ) does not escape or validate header values in CONNECT and CONNECTED frames, so raw newline ( \n ) characters in a header value are written directly to the wire, allowing an attacker who controls a header value to inject additional STOMP headers. This happens because the encoder intentionally skips escaping for CONNECT/CONNECTED frames per the STOMP 1.2 specification but never rejects the raw newlines, and since a broker parses each line as a separate header, an attacker controlling a value such as a user-supplied login or passcode can overwrite connection parameters or add authentication/role headers to bypass authentication or escalate privileges (the actual impact is broker-dependent). The issue is fixed in versions 4.1.136.Final and 4.2.16.Final.

Vulnerability Title
Netty 输入验证错误漏洞
Vulnerability Description
Netty是Netty团队开源的一款非阻塞I/O客户端-服务器框架,它主要用于开发Java网络应用程序,如协议服务器和客户端等。 Netty 4.1.136.Final之前版本和4.2.16.Final之前版本存在输入验证错误漏洞,该漏洞源于STOMP编码器未对CONNECT和CONNECTED帧中的标头值进行转义或验证,导致原始换行字符直接写入,攻击者可通过控制标头值注入额外STOMP标头,从而覆盖连接参数或添加认证/角色头,可能绕过身份验证或提升权限。
