| Title | Shenzhen Tenda Technology Co., Ltd. Tenda AC8v4 Router Tenda AC8v4 (V16.03.34.06) Buffer Overflow |
|---|
| Description | A 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.
