CVSS: 8.2EPSS: 0%CPEs: 6EXPL: 0CVE-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') •
CVSS: 7.5EPSS: 2%CPEs: 6EXPL: 1CVE-2019-16785 – HTTP Request Smuggling: LF vs CRLF handling in Waitress
https://notcve.org/view.php?id=CVE-2019-16785
Waitress through version 1.3.1 implemented a "MAY" part of the RFC7230 which states: "Although the line terminator for the start-line and header fields is the sequence CRLF, a recipient MAY recognize a single LF as a line terminator and ignore any preceding CR." Unfortunately if a front-end server does not parse header fields with an LF the same way as it does those with a CRLF it can lead to the front-end and the back-end server parsing the same HTTP message in two different ways. This can lead to a potential for HTTP request smuggling/splitting whereby Waitress may see two requests while the front-end server only sees a single HTTP message. This issue is fixed in Waitress 1.4.0. Waitress versión hasta 1.3.1, implementó una parte "MAY" del RFC7230 que declara: "Aunque el terminador de línea para los campos de línea de inicio y encabezado es la secuencia CRLF, un receptor PUEDE reconocer un LF único como un terminador de línea e ignorar cualquier CR anterior". • https://access.redhat.com/errata/RHSA-2020:0720 https://docs.pylonsproject.org/projects/waitress/en/latest/#security-fixes https://github.com/Pylons/waitress/commit/8eba394ad75deaf9e5cd15b78a3d16b12e6b0eba https://github.com/Pylons/waitress/security/advisories/GHSA-pg36-wpm5-g57p 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 • CWE-444: Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') •
CVSS: 7.5EPSS: 0%CPEs: 6EXPL: 0CVE-2019-16786 – HTTP Request Smuggling: Invalid Transfer-Encoding in Waitress
https://notcve.org/view.php?id=CVE-2019-16786
Waitress through version 1.3.1 would parse the Transfer-Encoding header and only look for a single string value, if that value was not chunked it would fall through and use the Content-Length header instead. According to the HTTP standard Transfer-Encoding should be a comma separated list, with the inner-most encoding first, followed by any further transfer codings, ending with chunked. Requests sent with: "Transfer-Encoding: gzip, chunked" would incorrectly get ignored, and the request would use a Content-Length header instead to determine the body size of the HTTP message. This could allow for Waitress to treat a single request as multiple requests in the case of HTTP pipelining. This issue is fixed in Waitress 1.4.0. • https://access.redhat.com/errata/RHSA-2020:0720 https://docs.pylonsproject.org/projects/waitress/en/latest/#security-fixes https://github.com/Pylons/waitress/commit/f11093a6b3240fc26830b6111e826128af7771c3 https://github.com/Pylons/waitress/security/advisories/GHSA-g2xc-35jw-c63p 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 • CWE-444: Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') •

https://notcve.org/view.php?id=CVE-2018-12207
Improper invalidation for page table updates by a virtual guest operating system for multiple Intel(R) Processors may allow an authenticated user to potentially enable denial of service of the host system via local access. Una invalidación inapropiada de las actualizaciones de la tabla de páginas por parte de un sistema operativo invitado virtual para múltiples procesadores Intel® puede habilitar a un usuario autenticado para permitir potencialmente una denegación de servicio del sistema host por medio de un acceso local. A flaw was found in the way Intel CPUs handle inconsistency between, virtual to physical memory address translations in CPU's local cache and system software's Paging structure entries. A privileged guest user may use this flaw to induce a hardware Machine Check Error on the host processor, resulting in a severe DoS scenario by halting the processor. System software like OS OR Virtual Machine Monitor (VMM) use virtual memory system for storing program instructions and data in memory. Virtual Memory system uses Paging structures like Page Tables and Page Directories to manage system memory. • http://lists.opensuse.org/opensuse-security-announce/2019-12/msg00042.html https://access.redhat.com/errata/RHSA-2019:3916 https://access.redhat.com/errata/RHSA-2019:3936 https://access.redhat.com/errata/RHSA-2019:3941 https://access.redhat.com/errata/RHSA-2020:0026 https://access.redhat.com/errata/RHSA-2020:0028 https://access.redhat.com/errata/RHSA-2020:0204 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/I5WWPW4BSZDDW7VHU427XTVXV7ROOFFW https:/&#x • CWE-20: Improper Input Validation CWE-226: Sensitive Information in Resource Not Removed Before Reuse •
