How to fix?

Upgrade SLES:15.3 jetty-http to version 9.4.42-3.9.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream jetty-http package and not the jetty-http package as distributed by SLES. See How to fix? for SLES:15.3 relevant fixed versions and status.

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.
