CVE-2019-16789 – HTTP Request Smuggling in Waitress: Invalid whitespace characters in headers
https://notcve.org/view.php?id=CVE-2019-16789
In Waitress through version 1.4.0, if a proxy server is used in front of waitress, an invalid request may be sent by an attacker that bypasses the front-end and is parsed differently by waitress leading to a potential for HTTP request smuggling. Specially crafted requests containing special whitespace characters in the Transfer-Encoding header would get parsed by Waitress as being a chunked request, but a front-end server would use the Content-Length instead as the Transfer-Encoding header is considered invalid due to containing invalid characters. If a front-end server does HTTP pipelining to a backend Waitress server this could lead to HTTP request splitting which may lead to potential cache poisoning or unexpected information disclosure. This issue is fixed in Waitress 1.4.1 through more strict HTTP field validation. En Waitress versiones hasta 1.4.0, si un servidor proxy es usado frente a waitress, un atacante puede enviar una petición no comprobada que omita el front-end y que waitress analiza de manera diferente conllevando a un posible trafico no autorizado de peticiones HTTP. • https://access.redhat.com/errata/RHSA-2020:0720 https://docs.pylonsproject.org/projects/waitress/en/latest/#security-fixes https://github.com/Pylons/waitress/commit/11d9e138125ad46e951027184b13242a3c1de017 https://github.com/github/advisory-review/pull/14604 https://lists.debian.org/debian-lts-announce/2022/05/msg00011.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/GVDHR2DNKCNQ7YQXISJ45NT4IQDX3LJ7 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedorapr • CWE-444: Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') •
