VAR-202509-0020

Vulnerability from variot - Updated: 2025-09-18 23:17

A vulnerability was identified in Tenda CH22 1.0.0.1. This issue affects the function formSetSambaConf of the file /goform/SetSambaConf. The manipulation of the argument samba_userNameSda leads to buffer overflow. It is possible to initiate the attack remotely. The exploit is publicly available and might be used. Shenzhen Tenda Technology Co.,Ltd. of ch22 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 samba_userNameSda parameter in the /goform/SetSambaConf 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
