The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2021:1509 advisory.
jetty: Symlink directory exposes webapp directory contents (CVE-2021-28163)
jetty: Ambiguous paths can access WEB-INF (CVE-2021-28164)
jetty: Resource exhaustion when receiving an invalid large TLS frame (CVE-2021-28165)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
