TITLE

Tenda AC6 buffer overflow vulnerability (CNVD-2025-26160)

Trust: 0.6

sources: CNVD: CNVD-2025-26160

DESCRIPTION

A vulnerability has been found in Tenda AC6 15.03.06.50. This issue affects some unknown processing of the file /goform/WifiGuestSet of the component HTTP Request Handler. Such manipulation of the argument shareSpeed leads to stack-based buffer overflow. The attack may be launched remotely. The exploit has been disclosed to the public and may be used. The Tenda AC6 is a wireless router manufactured by Tenda, a Chinese company. This vulnerability stems from the fact that the parameter `shareSpeed` in the file `/goform/WifiGuestSet` fails to properly validate the length of the input data. Attackers could exploit this vulnerability to execute arbitrary code on the system or cause a denial-of-service attack
