VAR-202511-0001

Vulnerability from variot - Updated: 2025-11-19 23:28

A weakness has been identified in Tenda AC23 16.03.07.52. This impacts the function formSetVirtualSer of the file /goform/SetVirtualServerCfg. This manipulation of the argument list causes buffer overflow. It is possible to initiate the attack remotely. The exploit has been made available to the public and could be exploited. The Tenda AC23 is a dual-band wireless router for home use, designed for large homes with excellent coverage and high-speed transmission. It supports 802.11ac Wave2 technology and boasts a maximum concurrent dual-band speed of 2033Mbps. This vulnerability stems from the fact that the formSetVirtualSer function parameter list in the file /goform/SetVirtualServerCfg fails to properly validate the length of the input data. Attackers could exploit this vulnerability to execute arbitrary code or cause a denial-of-service attack
