other urn:Belkin:service:firmwareupdate:1#UpdateFirmware↗

command UpdateFirmware↗

• → Detect HTTP POST requests targeting the Belkin WeMo UPnP firmware update endpoint /upnp/control/firmwareupdate1 with the SOAPACTION header containing 'UpdateFirmware'. ↗
• → Monitor for UPnP SOAP requests to port 49153 on Belkin WeMo devices, particularly those referencing external firmware URLs in the request body. ↗
• → Inspect SOAP body for a firmware URL element pointing to an external/attacker-controlled host (e.g., http://10.0.1.99/bad_firmware.bin) as an indicator of exploitation attempt. ↗

• · The exploit targets any Belkin WeMo Switch firmware version prior to WeMo_US_2.00.2176.PVT; devices running this or later versions are not vulnerable. ↗
• · The attacker-supplied firmware URL in the PoC is a local network address (10.0.1.99); real-world attacks may use any reachable URL, so detection should not be limited to RFC-1918 addresses. ↗
