Description Pedro Sampaio 2021-04-01 17:46:45 UTC 
In Eclipse Jetty 9.4.37.v20210219 to 9.4.38.v20210224, the default compliance mode allows requests with URIs that contain %2e or %2e%2e segments to access protected resources within the WEB-INF directory. For example a request to /context/%2e/WEB-INF/web.xml can retrieve the web.xml file. This can reveal sensitive information regarding the implementation of a web application.

Comment 8 Jonathan Christison 2021-04-21 11:42:18 UTC 
Marking Red Hat Camel K as having a low impact, although Camel K distributes jetty artifacts through camel-jetty, camel-jetty itself is not available for use by the application developer, http functionality is provided by camel-k default runtime, Quarkus.
Comment 12 Todd Cullum 2021-04-27 20:02:51 UTC 
Statement:

Red Hat OpenStack Platform's OpenDaylight will not be updated for this flaw because it was deprecated as of OpenStack Platform 14 and is only receiving security fixes for Important and Critical flaws.

Red Hat CodeReady Studio 12 is not affected by this vulnerability because it does not ship a vulnerable version of jetty.
