The device runs a CGI binary (index.cgi) to offer a management web application. Once authenticated with valid credentials in this web portal, a potential attacker could submit any \"Address\" value and it would be copied to a second variable with a \"strcpy\" vulnerable function without checking its length. Because of this, it is possible to send a long address value to overflow the process stack, controlling the function return address.CVE-2022-1669 has been assigned to this vulnerability. A CVSS v3 base score of 6.8 has been assigned; the CVSS vector string is (AV:N/AC:H/PR:L/UI:N/S:U/C:N/I:H/A:H).",
