NVD Description
Note: Versions mentioned in the description apply only to the upstream eap7-jcl-over-slf4j package and not the eap7-jcl-over-slf4j package as distributed by RHEL.
See How to fix? for RHEL:7 relevant fixed versions and status.
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.
