Описание

Netty is an asynchronous, event-driven network application framework. Prior to 4.2.13.Final and 4.1.133.Final, HttpClientCodec pairs each inbound response with an outbound request by queue.poll() once per response, including for 1xx. If the client pipelines GET then HEAD and the server sends 103, then 200 with GET body, then 200 for HEAD, the queue pairs HEAD with the first 200. The HEAD rule then skips reading that message’s body, so the GET entity bytes stay on the stream and the following 200 is parsed from the wrong offset. This vulnerability is fixed in 4.2.13.Final and 4.1.133.Final.

A flaw was found in Netty, an asynchronous, event-driven network application framework. A remote attacker could exploit this vulnerability by sending a specific sequence of HTTP responses (103, followed by a 200 with a GET body, then another 200 for a HEAD request) when the client pipelines GET then HEAD requests. This can cause the HttpClientCodec to incorrectly pair responses, leading to subsequent HTTP responses being parsed from the wrong offset. This issue may result in information disclosure or other data integrity problems due to misinterpretation of network traffic.

Отчет

Important: A flaw in Netty's HttpClientCodec allows a remote attacker to cause data confusion. By sending a specially crafted sequence of HTTP responses, an attacker can cause subsequent HTTP responses to be parsed incorrectly, potentially leading to information disclosure or data integrity issues in applications utilizing Netty for HTTP client operations. This vulnerability affects various Red Hat products that bundle Netty, including Red Hat AMQ, Enterprise Application Platform, Red Hat Build of Quarkus, and Red Hat Build of Keycloak.
