CVE-2017-7559

undertow: HTTP Request smuggling vulnerability (incomplete fix of CVE-2017-2666)

Published Jan 10, 2018 CVSS 3.0 · 6.1 Medium EPSS 1.9% KEV · Not listed
Description
In Undertow 2.x before 2.0.0.Alpha2, 1.4.x before 1.4.17.Final, and 1.3.x before 1.3.31.Final, it was found that the fix for CVE-2017-2666 was incomplete and invalid characters are still allowed in the query string 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.
