CVE-2019-16785 (CNNVD-201912-974)
中文标题:
Waitress 环境问题漏洞
英文标题:
HTTP Request Smuggling: LF vs CRLF handling in Waitress
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 1.3.1及之前版本中存在环境问题漏洞。远程攻击者可借助特制HTTP响应利用该漏洞导致HTTP请求走私。
英文描述:
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.
