Vulnerability Discussion

The Secondary Logon service provides a means for entering alternate credentials, typically used to run commands with elevated privileges. Using privileged credentials in a standard user session can expose those credentials to theft.

Check

Run "Services.msc".

Locate the "Secondary Logon" service.

If the "Startup Type" is not "Disabled" or the "Status" is "Running", this is a finding.

Fix

Configure the "Secondary Logon" service "Startup Type" to "Disabled".
