"According to its self-reported version, the Tenable Nessus application
running on the remote host is prior to 7.0.3. It is, therefore,
affected by a local privilege escalation vulnerability due to the
program failing to enforce secure permissions for sub-directories when
a directory is installed outside of the default location.

This plugin is only checking the remote version and has not checked
for installation location.");
