CVE-2022-1669
A buffer overflow vulnerability has been detected in the firewall function of the device management web portal. The device runs a CGI binary (index.cgi) to offer a management web application.

Because of this, it is possible to send a long address value to overflow the process stack, controlling the function return address.
