Submit #654460: tenda AC20 <= V16.03.08.12 (latest) Buffer Overflowinfo

Titletenda AC20 <= V16.03.08.12 (latest) 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 well-crafted http post packet to the request path /goform/SetPptpServerCfg, triggering a denial of service attack or even RCE, specifically via the function strcpy(s + 2, var); because there is no bounds check on s, causing a stack overflow
