Debian LTS Advisory DLA-2688-1 [email protected]
https://www.debian.org/lts/security/ Sylvain Beucler

Package : jetty9
Version : 9.2.30-0+deb9u2
CVE ID : CVE-2021-28169
Steven Seeley discovered that in jetty, a Java servlet engine and
webserver, requests to the ConcatServlet and WelcomeFilter are able to
access protected resources within the WEB-INF directory. An attacker
may access sensitive information regarding the implementation of a web
application.
For Debian 9 stretch, this problem has been fixed in version
9.2.30-0+deb9u2.
We recommend that you upgrade your jetty9 packages.
For the detailed security status of jetty9 please refer to
its security tracker page at:
https://security-tracker.debian.org/tracker/jetty9
