CVE-2020-7238 – netty: HTTP Request Smuggling due to Transfer-Encoding whitespace mishandling

https://notcve.org/view.php?id=CVE-2020-7238

Netty 4.1.43.Final allows HTTP Request Smuggling because it mishandles Transfer-Encoding whitespace (such as a [space]Transfer-Encoding:chunked line) and a later Content-Length header. This issue exists because of an incomplete fix for CVE-2019-16869. Netty versión 4.1.43.Final, permite el tráfico no autorizado de peticiones HTTP porque maneja inapropiadamente el espacio en blanco de Transfer-Encoding (tal y como una línea [space]Transfer-Encoding:chunked) y un encabezado Content-Length posterior. Este problema existe debido a una corrección incompleta para el CVE-2019-16869. A flaw was found in Netty, where it mishandles Transfer-Encoding whitespace. • https://access.redhat.com/errata/RHSA-2020:0497 https://access.redhat.com/errata/RHSA-2020:0567 https://access.redhat.com/errata/RHSA-2020:0601 https://access.redhat.com/errata/RHSA-2020:0605 https://access.redhat.com/errata/RHSA-2020:0606 https://access.redhat.com/errata/RHSA-2020:0804 https://access.redhat.com/errata/RHSA-2020:0805 https://access.redhat.com/errata/RHSA-2020:0806 https://access.redhat.com/errata/RHSA-2020:0811 https://github.com/jdordonezn/CVE-2020&# • CWE-444: Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') •
