VAR-202504-3237

Vulnerability from variot - Updated: 2025-08-02 23:13

A vulnerability classified as critical was found in Tenda W12 and i24 3.0.0.4(2887)/3.0.0.5(3644). Affected by this vulnerability is the function cgidhcpsCfgSet of the file /goform/modules of the component httpd. The manipulation of the argument json leads to stack-based buffer overflow. The attack can be launched remotely. The exploit has been disclosed to the public and may be used. Shenzhen Tenda Technology Co.,Ltd. of W12 firmware and i24 The firmware contains a buffer error vulnerability and a stack-based buffer overflow vulnerability.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. The vulnerability is caused by the failure of the parameter json in /goform/modules to correctly verify the length of the input data. Attackers can exploit this vulnerability to execute arbitrary code on the system or cause a denial of service
