The remote Redhat Enterprise Linux 7 / 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2021:3758 advisory.
jetty: requests to the ConcatServlet and WelcomeFilter are able to access protected resources within the WEB-INF directory (CVE-2021-28169)
golang: archive/zip: malformed archive may cause panic or memory exhaustion (CVE-2021-33196)
jetty: SessionListener can prevent a session from being invalidated breaking logout (CVE-2021-34428)
openvswitch: use-after-free in decode_NXAST_RAW_ENCAP during the decoding of a RAW_ENCAP action (CVE-2021-36980)
coreos-installer: restrict access permissions on /boot/ignition{,/config.ign} (CVE-2021-3917)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
