The Shadowserver Foundation

Accessible CPE WAN Management Protocol (CWMP) Scanning Project

If you are looking at this page, then more than likely, you noticed a scan coming from this server across your network and/or poking at the CWMP service on port 7547/TCP.

The Shadowserver Foundation is currently undertaking a project to search for publicly accessible devices that have the CWMP service accesible. The goal of this project is to identify openly accessible systems that have the CWMP service accessible and report them back to the network owners for remediation.

CWMP services that we have found have been incorporated into our reports and are being reported on a daily basis.

Methodology

We are querying all computers with routable IPv4 addresses that are not firewalled from the internet on port 7547/tcp with a simple "GET /" and capturing the response. We intend no harm, but if we are causing problems, please contact us at gro [tod] revfooreswodahs [ta] nacbarssnd

If you would like to test your own device to see if it has cwmp accessible, try the command: "curl http://[IP]:7547/" and look for a response.

Whitelisting

To be removed from this set of scanning you will need to send an email to dnsscan [at] shadowserver [dot] org with the specific CIDR's that you would like to have removed. You will have to be the verifiable owner of these CIDR's and be able to prove that fact. Any address space that is whitelisted will be publicly available here: https://cwmpscan.shadowserver.org/exclude.html
