VAR-202508-0592

Vulnerability from variot - Updated: 2025-11-19 23:27

A vulnerability was determined in Tenda AC20 up to 16.03.08.12. Affected is an unknown function of the file /goform/WifiGuestSet. The manipulation of the argument shareSpeed leads to buffer overflow. It is possible to launch the attack remotely. The exploit has been disclosed to the public and may be used. Shenzhen Tenda Technology Co.,Ltd. of AC20 The firmware contains a buffer error vulnerability and a classic buffer overflow vulnerability.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. This vulnerability stems from the failure of the shareSpeed parameter in the /goform/WifiGuestSet file to properly validate the length of input data. An attacker could exploit this vulnerability to execute arbitrary code on the system or cause a denial of service
