CVE-2019-20444: XSS

Published Jan 29, 2020
·
Updated

A HTTP smuggling flaw was found in HttpObjectDecoder.java in Netty in versions prior to version 4.1.44. HTTP headers with an invalid fold, in this case CRLF (carriage return, line feed) without being followed by SP (space) or HTAB (horizontal tab), result in situations where headers can be misread. Data integrity is the highest threat with this vulnerability.

Other sources

A vulnerability was found in HttpObjectDecoder.java in Netty before 4.1.44 allows an HTTP header that lacks a colon, which might be interpreted as a separate header with an incorrect syntax, or might be interpreted as an "invalid fold."

Reference: https://github.com/netty/netty/issues/9866 https://github.com/netty/netty/compare/netty-4.1.43.Final...netty-4.1.44.Final

— Red Hat

Netty is vulnerable to HTTP request smuggling, caused by a flaw in the HttpObjectDecoder.java. By sending a specially-crafted request, an attacker could exploit this vulnerability to poison the web cache, bypass web application firewall protection, and conduct XSS attacks.
