Submit #657126: Tenda AC21 ≤V16.03.08.16 Buffer Overflowinfo

TitleTenda AC21 ≤V16.03.08.16 Buffer Overflow
DescriptionA buffer overflow vulnerability was discovered on the latest version of the Tenda AC21 router, V16.03.08.16, where an attacker sent a well-crafted http post packet to the request path /goform/WifiExtraSet, triggering a denial of service attack or even RCE, specifically via the function strcpy(tkip_aes, tkip_aes_1); because there is no bounds check on tkip_aes, causing a stack overflow
