VAR-202508-2273

Vulnerability from variot - Updated: 2025-09-19 23:15

A flaw has been found in Tenda CH22 1.0.0.1. This vulnerability affects the function formeditUserName of the file /goform/editUserName. Executing manipulation of the argument new_account can lead to buffer overflow. It is possible to launch the attack remotely. The exploit has been published and may 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.

The Tenda CH22 suffers from a buffer overflow vulnerability caused by a failure to properly validate the length of input data in the parameter "new_account" in the file "/goform/editUserName." This vulnerability could allow an attacker to execute arbitrary code on the system or cause a denial of service
