[R1] Nessus Network Monitor 5.13.0 Fixes One Third-party Vulnerability

Medium

Synopsis

Nessus Network Monitor leverages third-party software to help provide
underlying functionality. One of the third-party components (jQuery) was found
to contain vulnerabilities, and updated versions have been made available by
the providers.

Out of caution and in line with good practice, Tenable opted to upgrade the
bundled jQuery components to address the potential impact of these issues.
Nessus Network Monitor 5.13.0 updates jQuery to version 3.5.1 to address the
identified vulnerabilities.

Solution

Tenable has included a fix in Nessus Network Monitor 5.13.0 to address this
issue. The installation files can be obtained from the Tenable Downloads Portal
( https://www.tenable.com/downloads/nessus-network-monitor ).
