GHSA-gwcr-j4wh-j3cq · 深刻度: medium · エコシステム: maven — Jetty Utility Servlets ConcatServlet Double Decoding Information Disclosure Vulnerability
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.
