Vulnerability from variot - Updated: 2025-11-19 23:24

A weakness has been identified in Tenda CH22 1.0.0.1. Affected is the function fromwebExcptypemanFilter of the file /goform/webExcptypemanFilter. Executing manipulation of the argument page can lead to buffer overflow. The attack may be launched remotely. The exploit has been made available to the public and could be exploited. The Tenda CH22 is a network device manufactured by Tenda, a Chinese company.

Version 1.0.0.1 of the Tenda CH22 contains a buffer overflow vulnerability. This vulnerability stems from the fact that the parameter page in the file /goform/webExcptypemanFilter 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
