| Title | Tenda AC8 V16.03.33.05 Denial of Service |
|---|
| Description | A buffer overflow vulnerability exists in the Tenda AC8 router running firmware version V16.03.33.05. The flaw originates from the fast_setting_wifi_set interface in the embedded httpd service, which fails to properly validate user-supplied input in the timeZone parameter. An attacker can exploit this vulnerability by sending a specially crafted HTTP request with an overly long timeZone value, potentially leading to a denial-of-service (DoS) condition.
