NVD Description

Note: Versions mentioned in the description apply only to the upstream jetty-util package and not the jetty-util package as distributed by Centos. See How to fix? for Centos:7 relevant fixed versions and status.

For Eclipse Jetty versions <= 9.4.40, <= 10.0.2, <= 11.0.2, it is possible for requests to the ConcatServlet with a doubly encoded path to access protected resources within the WEB-INF directory. For example a request to /concat?/%2557EB-INF/web.xml can retrieve the web.xml file. This can reveal sensitive information regarding the implementation of a web application.
