They will provide a patch and they will allow you to disable that support account. HP will just have a new private back door account though.
Who thought it was a good idea to have a support account that could reset the device to factory defaults? How many customers screwed their config up so bad and locked themselves out that they had to call HP to wipe the box?
Not as bad a Netscreen firewalls though; if you have the serial number, you can use it to wipe a firewall as long as you can get access via CLI or GUI to it.
