How to fix?
Upgrade io.netty:netty-all
to version 4.1.44.Final or higher.
Overview
io.netty:netty-all is an asynchronous event-driven network application framework for rapid development of maintainable high performance protocol servers & clients.
Affected versions of this package are vulnerable to HTTP Request Smuggling due to the package mishandling Transfer-Encoding whitespace (such as a [space]Transfer-Encoding:chunked
line) and a later Content-Length header when using HTTP/1.1
. This issue exists because of an incomplete fix for CVE-2019-16869.
