| 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 WifiGuestSet interface in the embedded httpd service, which fails to properly validate user-supplied input in the shareSpeed parameter.
An attacker can exploit this vulnerability by sending a specially crafted HTTP request with an overly long value, potentially leading to a denial-of-service condition. |
