CVE-2019-16789 (CNNVD-201912-1120)
中文标题:
Waitress 环境问题漏洞
英文标题:
HTTP Request Smuggling in Waitress: Invalid whitespace characters in headers
漏洞描述
中文描述:
Waitress是一款用于Python的WSGI（Web服务器网关接口）服务器。 Waitress 1.4.0及之前版本中存在环境问题漏洞。攻击者可利用该漏洞注入任意的HTTP请求，导致浏览器发送两个请求，造成缓存中毒或获取信息。
英文描述:
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.
