| The Bluesound POWERNODE is a "Wireless Stereo Component", which allows the user to stream to an older analogue sound system. It also includes an amp. I (sadly) happen to have such a device at home and decided to take a look at the firmware. The results were as expected. Most of the product line appears to be vulnerable, since they run mostly the same software. I would also be surprised if this is the only vulnerability in the device.
