using OpenVAS, I performed a vulnerability scan of my CentOS7 server (there is Apache Nifi in version 1.7.1 with 8081 port). I obtained the following report:

[..] solution: Upgrade to Eclipse Jetty Server version 9.3.24.v20180605 or 9.4.11.v20180605 or later..
Unfortunately, I could not find a solution to the problem regarding upgrade Eclipse Jetty Server for Apache Nifi.
Has anyone had a similar problem? The case is fresh.
You can do this manually on your instance by changing the Jetty dependency version in
<jetty.version>9.4.3.v20170317</jetty.version>). There is an Apache Jira (NIFI-5479) to upgrade this in the core project. Please do not comment on that ticket indicating this is related to a security vulnerability, as the Apache Security Vulnerability Reporting Process must be followed.
Ok thanks for your answer, but, in which specifically the pom.xml file should be added a row:<jetty.version>9.4.3.v20170317</jetty.version>?
The root pom file located at
nifi/pom.xml in the project structure should be modified so the existing
jetty.version value is changed from
9.4.11.v20180605. Initial analysis suggests upgrading the Jetty version will cause runtime errors, as their handling of TLD loading has changed and is currently incompatible with how NiFi works.
