Summary
Eclipse Jetty libraries (jetty-io, jetty-client, jetty-http, jetty-util) used by IBM Tivoli Network Manager, in 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.All the libraries are upgraded to 9.4.45.v20220203 to address the issue.
