Submit #639031: Tenda AC20 <= V16.03.08.12 Buffer Overflowinfo

TitleTenda AC20 <= V16.03.08.12 Buffer Overflow
DescriptionA buffer overflow vulnerability was discovered on the latest version of the Tengda AC20 router, V16.03.08.12, where an attacker sent a carefully constructed http post packet to the request path /goform/SetNetControlList triggered, resulting in a denial of service attack or even RCE, specifically through the function sscanf(s_1, "; %[^; ]; %[^; ]; %[^; ]; %[^; ]; ", &v9, Var, nptr, nptr_1); implemented, because there is no boundary check on the s_1
