Submit #551893: Shenzhen Tenda Technology Co.,Ltd. AC1206 V15.03.06.23 Buffer Overflowinfo

TitleShenzhen Tenda Technology Co.,Ltd. AC1206 V15.03.06.23 Buffer Overflow
DescriptionTenda `AC1206 V15.03.06.23` firmware has a buffer overflow vulnerability in the form_fast_setting_wifi_set function. The function `sscanf(timestr + 1, "%[^:]:%s", timespand, timespand[1])` will copy the timezone string content to timespand without doing a boundary check, causing a buffer overflow and overwriting the memory area after the array, which may cause the program to crash or even remote code execution, thereby triggering this security vulnerability.
