A vulnerability has been discovered that affects the certificate verification
functions provided by the HNDS service found on the Centro Grande (ADB version)

through the web management interface, under Settings => Router => Firmware
section. The version 6.14.00 should be installed. If it is not the case, the
update can be forced cliking on the button labeled "Check for upgrade".
