Submit #628117: Tenda TX3 US_TX3V1.0br_V16.03.13.11_multi_TDE01 Buffer Overflowinfo

TitleTenda TX3 US_TX3V1.0br_V16.03.13.11_multi_TDE01 Buffer Overflow
Descriptionhttps://github.com/TangcuLiyuu/CVE/issues/1 The problem occurs in the httpd component, where the program calls form_fast_setting_wifi_set to handle requests related to fast_setting_wifi_set. In the form_fast_setting_wifi_set function, the program first retrieves the ssid parameter using the websGetVar function and stores it in a variable called Var. It then assigns the value of Var to Var_1. Finally, it uses the strcpy function to directly copy the value of Var_1 into the buffer par. Since there is no length limitation on the parameter, an attacker can construct an overly long parameter to trigger a buffer overflow vulnerability, resulting in device crashes.
