Title:	Eclipse Jetty Information Disclosure Vulnerability (GHSA-gwcr-j4wh-j3cq)
Summary:	Eclipse Jetty is prone to an information disclosure vulnerability; in the ConcatServlet and WelcomeFilter servlet.
Description:	Summary: Eclipse Jetty is prone to an information disclosure vulnerability in the ConcatServlet and WelcomeFilter servlet. Vulnerability Insight: Requests to the ConcatServlet and WelcomeFilter are able to access protected resources within the WEB-INF directory. For example a request to the ConcatServlet with a URI of /concat?/%2557EB-INF/web.xml can retrieve the web.xml file. This can reveal sensitive information regarding the implementation of a web application. This occurs because both ConcatServlet and WelcomeFilter decode the supplied path to verify it is not within the WEB-INF or META-INF directories. It then uses this decoded path to call RequestDispatcher which will also do decoding of the path. This double decoding allows paths with a doubly encoded WEB-INF to bypass this security check. Affected Software/OS: Eclipse Jetty prior to version 9.4.41, 10.x through 10.0.2 and 11.x through 11.0.2. Solution: Update to version 9.4.41, 10.0.3, 11.0.3 or later. CVSS Score: 5.0 CVSS Vector: AV:N/AC:L/Au:N/C:P/I:N/A:N
