Stack-based buffer overflow in the Boa Web Server component of Tenda HG7, HG9 and HG10 XPON gateways running firmware 300001138_en_xpon allows remote, unauthenticated attackers to corrupt memory by sending a crafted request to the /boaform/formLoopBack endpoint with an oversized Ethtype argument. The assessed CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H, base 9.8) confirms no authentication or user interaction is required, and publicly available exploit code exists, so the practical risk hinges on whether the device's management web interface is reachable from the WAN or another untrusted network. Impact is bounded to these specific XPON gateway firmware builds.
