Authenticated code execution via unchecked SSID copy
Published Jul 31, 2024 · Updated Aug 21, 2024
Stack-based buffer overflow in Tenda AC18 15.03.3.10 allows remote authenticated users to execute arbitrary code through a crafted SSID. The form_fast_setting_wifi_set handler copies the attacker-controlled ssid value into fixed-size stack buffers without checking its length. Access to the router's Wi-Fi configuration interface is required, and successful exploitation compromises the embedded device.
