HIGH: Accessible Radmin Report



This report identifies hosts that have a Radmin service running on port 4899/TCP and accessible from the Internet. As with all remote access tools, care should be taken to make sure the service is configured in a secure manner and the security implications of making it accessible from anywhere on the Internet taken into account.

You can track the latest Radmin scan results on our Dashboard.

We first announced the scan in a blog post titled Accessible Radmin Report – Exposed Radmin Services on the Internet.
