| Description |
|---|
| Having portproxy enabled or configured in Windows 10 could allow a man-in-the-middle attack. |
| ℹ️ Check |
|---|
| Check the registry key for existence of proxied ports: HKLM\SYSTEM\CurrentControlSet\Services\PortProxy\. If the key contains v4tov4\tcp\ or is populated v4tov4\tcp\, this is a finding. Run "netsh interface portproxy show all". If the command displays any results, this is a finding. |
| ✔️ Fix |
|---|
| Contact the Administrator to run "netsh interface portproxy delete" with elevation. Remove any enabled portproxies that may be configured. |
