  - CVE-2025-10401: The affected element is an unknown function of the file /goform/diag_ping.
  Performing manipulation of the argument target_addr results in command injection. Remote
  exploitation of the attack is possible.

  - CVE-2025-25740: Stack-based buffer overflow vulnerability via the PSK parameter in the
  SetQuickVPNSettings module

  - CVE-2025-25741: Stack-based buffer overflow vulnerability via the IPv6_PppoePassword
  parameter in the SetIPv6PppoeSettings module

  - CVE-2025-25742: Stack-based buffer overflow vulnerability via the AccountPassword parameter
  in the SetSysEmailSettings module

  - CVE-2025-25743: Command injection vulnerability in the SetVirtualServerSettings module

  - CVE-2025-25744: Stack-based buffer overflow vulnerability via the Password parameter in the
  SetDynamicDNSSettings module

  - CVE-2025-25745: Stack-based buffer overflow vulnerability via the Password parameter in the
  SetQuickVPNSettings module

  - CVE-2025-25746: Stack-based buffer overflow vulnerability via the Password parameter in the
  SetWanSettings module

  - CVE-2025-55848: RCE vulnerability in the set_cassword settings interface, as the http_casswd
  parameter is not filtered by '&' to allow injection of reverse connection commands

  - CVE-2025-11092: Command injection vulnerability in the function sub_412E7C of the file
  /goform/set_switch_settings. Manipulation of the argument port causes command injection

  - CVE-2025-11095: Command injection vulnerability in the file /goform/delete_offline_device.
  Manipulation of the argument delvalue results in command injection

  - CVE-2025-11097: Command injection vulnerability in the file /goform/set_device_name.
  Manipulation of the argument mac leads to command injection

  - CVE-2025-11098: Command injection vulnerability in the file /goform/set_wifi_blacklists.
  Manipulation of the argument macList results in command injection

  - CVE-2025-11099: Command injection vulnerability in the function uci_del of the file
  /goform/delete_prohibiting. Manipulation of the argument delvalue causes command injection

  - CVE-2025-11100: Command injection vulnerability in the function uci_set of the file
  /goform/set_wifi_blacklists. Such manipulation leads to command injection");

  script_tag(name:"solution", value:"No solution was made available by the vendor. General solution
  options are to upgrade to a newer release, disable respective features, remove the product or
  replace the product by another one.
