MikroTik Router Management Ports May Be Exposed to Internet, Posing Security Risk

MikroTik routers may have management services like Winbox accessible from the internet due to old rules or configuration errors. This exposure allows anyone to attempt login, and outdated devices have been compromised in the past through vulnerabilities like CVE-2018-14847. Testing from inside a local network is insufficient; verification requires an external connection to the router's public IP. The article provides guidance on how to scan for open ports and configure firewall rules to restrict access. It also recommends using a VPN for management and keeping RouterOS updated.
