Submit #664923: Shenzhen Tenda Technology Co.,Ltd. AC23 <= V16.03.07.52 Buffer Overflowinfo

TitleShenzhen Tenda Technology Co.,Ltd. AC23 <= V16.03.07.52 Buffer Overflow
DescriptionA buffer overflow vulnerability was discovered on the latest version of the Tengda AC23 router, V16.03.07.52, where an attacker sent a well-crafted http post packet to the request path /goform/SetStaticRouteCfg, triggering a denial of service attack or even RCE, specifically via the function sscanf(s_4, "%[^,],%[^,],%[^,],%s", v15, v16, v17, v18) because there is no bounds check on s_4, causing a stack overflow
