Descriptions

Netty is an asynchronous event-driven network application framework for rapid development of maintainable high performance protocol servers & clients. The `HttpPostRequestDecoder` can be tricked to accumulate data. While the decoder can store items on the disk if configured so, there are no limits to the number of fields the form can have, an attacher can send a chunked post consisting of many small fields that will be accumulated in the `bodyListHttpData` list. The decoder cumulates bytes in the `undecodedChunk` buffer until it can decode a field, this field can cumulate data without limits. This vulnerability is fixed in 4.1.108.Final.

Netty es un framework de aplicación de red asíncrono impulsado por eventos para el desarrollo rápido de servidores y clientes de protocolo de alto rendimiento mantenibles. Se puede engañar al `HttpPostRequestDecoder` para que acumule datos. Si bien el decodificador puede almacenar elementos en el disco si está configurado así, no hay límites para la cantidad de campos que puede tener el formulario, un adjunto puede enviar una publicación fragmentada que consta de muchos campos pequeños que se acumularán en la lista `bodyListHttpData`. El decodificador acumula bytes en el búfer `undecodedChunk` hasta que puede decodificar un campo, este campo puede acumular datos sin límites. Esta vulnerabilidad se soluciona en 4.1.108.Final.

A flaw was found in the io.netty:netty-codec-http package. Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling issues due to the accumulation of data in the HttpPostRequestDecoder. The decoder cumulates bytes in the undecodedChunk buffer until it can decode a field, allowing data to accumulate without limits. This flaw allows an attacker to cause a denial of service by sending a chunked post consisting of many small fields that will be accumulated in the bodyListHttpData list.
