Description

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.
