Remediation advice

Remediation steps
| Type | Step |
|---|---|
| Action |
Step 1: Check that any NAS devices are exposed to the Internet using the Security Counselor. If the Security Counselor shows “The System Administration service can be directly accessible from an external IP address via the following protocols: HTTP” then the device is exposed. Unexposed devices are not vulnerable. https://www.qnap.com/en/security-news/2022/take-immediate-actions-to-secure-qnap-nas |

Step 2: Disable port forwarding for NAS management port (443 and 8080 by default) on your router, virtual server, or NAT. Please note that this should only be done for IP addresses used by your NAS devices. https://www.qnap.com/en/security-news/2022/take-immediate-actions-to-secure-qnap-nas |
