| Título | Tenda AC7 AC7V1.0 V15.03.06.44 Buffer Overflow |
|---|
| Descrição | The Tenda AC7V1.0 V15.03.06.44 firmware has a stack overflow vulnerability in the fromSetSysTime function. The tmpstr variable receives the time parameter from a POST request and is assigned to year~sec by sscanf. However, since the user can control the input of time, the statement sscanf(tmpstr, "%[^-]-%[^-]-%[^ ] %[^:]:%[^:]:%s", year, month, day, hour, min, sec); can cause a buffer overflow. The user-provided time can exceed the capacity of the year~sec array, triggering this security vulnerability. |
