All,
Thought I'd bring this question/issue to our resident experts. We're standing up a new Greenfield environment and the Nessus scan is flagging our Media and IC servers with the High Vulnerability documented below.
Have any of you ran into this and were you able to mitigate?

SYNOPSIS:
At least one improperly configured Windows service may have a privilege escalation vulnerability.
DESCRIPTION:
At least one Windows service executable with insecure permissions was detected on the remote host. Services configured to use an executable with weak permissions are vulnerable to privilege escalation attacks.
An unprivileged user could modify or overwrite the executable with arbitrary code, which would be executed the next time the service is started. Depending on the user that the service runs as, this could result in privilege escalation.
This plugin checks if any of the following groups have permissions to modify executable files that are started by Windows services :
- Everyone
- Users
- Domain Users
- Authenticated Users
SOLUTION:
Ensure the groups listed above do not have permissions to modify or write service executables. Additionally, ensure these groups do not have Full Control permission to any directories that contain service executables.
