CVE-2017-7559: Inconsistent Interpretation of HTTP Requests (HTTP Request Smuggling)

January 10, 2018 (updated October 9, 2019)

Invalid characters are allowed in query strings and path parameters. This could be exploited, in conjunction with a proxy that also permitted the invalid characters but with a different interpretation, to inject data into the HTTP response. By manipulating the HTTP response the attacker could poison a web-cache, perform an XSS attack, or obtain sensitive information from requests other than their own.
