The firmware upgrade functionality, triggered via PubNub, retrieves signed firmware binaries using plain HTTP requests. The device doesn't check the kind of firmware image that is going to be installed and thus allows for flashing any signed firmware into any MCU. Since the device contains different and incompatible MCUs, flashing one firmware to the wrong MCU will result in a permanent brick condition. To trigger this vulnerability, an attacker needs to impersonate the remote server \"cache.insteon.com\" and serve a signed firmware image."}, {"lang": "es", "value": "Existe una vulnerabilidad explotable de denegaci\u00f3n de servicio (DoS) permanente en Insteon Hub, con la versi\u00f3n 1013 de firmware.
