Description

When installing Nessus to a directory outside of the default location, Nessus versions prior to 7.0.3 did not enforce secure permissions for sub-directories. This could allow for local privilege escalation if users had not secured the directories in the installation location.

How to fix

Upgrade to a fixed version: Tenable Nessus 7.0.3. Check the vendor advisory for mitigations.
