| 标题 | TOTOLINK A3002MU A3002MU_Hh-B20211125.1046 Stack-based Buffer Overflow |
|---|
| 描述 | In the binary file `/bin/boa`, the function formWlanSetup obtains the value of the **`wan-url`** parameter from the front-end HTTP request **without performing any length validation**. Subsequently, the value is copied into a **fixed-size buffer** using an unsafe string copy operation.
If an attacker sends a sufficiently long `wan-url` string, it will overflow the buffer and corrupt adjacent memory regions, resulting in a **buffer overflow vulnerability**. Successful exploitation could lead to denial of service (DoS) . |
