Summary

When installing Tenable Network Monitor to a non-default location on a Windows host, Tenable Network Monitor versions prior to 6.5.1 did not enforce secure permissions for sub-directories. This could allow for local privilege escalation if users had not secured the directories in the non-default installation location.
