The video above was just posted by well known HTC exploiter Justin Case @TeamAndIRC. He also included that this method would Root All HTC devices running Android 4.0- 4.2.2. These devices already have root methods. That being said this exploit will remain under wraps until it is needed. Verizon is preparing to release their version of the HTC One which I am certain will be locked down tight! Hopefully this new method could be used to gain root on this device. Justin has said the decision will be made as to whether or not this exploit will be released when the need for it arises.
