"The remote SUSE Linux SUSE15 host has packages installed that are affected by multiple vulnerabilities as referenced in
the openSUSE-SU-2021:2005-1 advisory.

  - In Eclipse Jetty 9.4.32 to 9.4.38, 10.0.0.beta2 to 10.0.1, and 11.0.0.beta2 to 11.0.1, if a user uses a
    webapps directory that is a symlink, the contents of the webapps directory is deployed as a static webapp,
    inadvertently serving the webapps themselves and anything else that might be in that directory.
    (CVE-2021-28163)

  - 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. (CVE-2021-28164)

  - In Eclipse Jetty 7.2.2 to 9.4.38, 10.0.0.alpha0 to 10.0.1, and 11.0.0.alpha0 to 11.0.1, CPU usage can
    reach 100% upon receiving a large invalid TLS frame. (CVE-2021-28165)

  - 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. (CVE-2021-28169)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
