CVE-2019-16869: XSS

Published Sep 26, 2019
·
Updated

A flaw was found in Netty, where whitespace before the colon in HTTP headers is mishandled. This flaw allows an attacker to cause HTTP request smuggling.

Other sources

Netty before 4.1.42.Final mishandles whitespace before the colon in HTTP headers (such as a "Transfer-Encoding : chunked" line), which leads to HTTP request smuggling.

Netty is vulnerable to HTTP request smuggling, caused by a flaw when handling unusual whitespaces before the colon in HTTP headers. 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.
