Submit #664065: Shenzhen Tenda Technology Co., Ltd. Tenda AC8v4 Router Tenda AC8v4 (V16.03.34.06) Buffer Overflowinfo

TitleShenzhen Tenda Technology Co., Ltd. Tenda AC8v4 Router Tenda AC8v4 (V16.03.34.06) Buffer Overflow
DescriptionA buffer overflow vulnerability exists in the /goform/SetServerConfig interface of the Tenda AC8v4 router (firmware version V16.03.34.06). An attacker can send a malicious POST request containing an overly long parameter, which triggers abnormal processing in the formSetServerConfig function. This causes the router's CPU usage to surge to 100%, ultimately leading to device freeze or service interruption, requiring a physical restart for recovery.
