If your affected product does not have a firmware fix available, NETGEAR strongly recommends that you follow this workaround procedure to remediate the vulnerability:
Manually enable the password recovery feature on your device.
For more information, visit Configuring router administrative password recovery.
Ensure that remote management is disabled.
Remote management is disabled by default. For more information, check the user manual for your product, which is available from http://www.netgear.com/support/.
The potential for password exposure remains if you do not complete both steps. NETGEAR is not responsible for any consequences that could have been avoided by following the recommendations in this notification.
