TITLE

Tenda CH22 buffer overflow vulnerability in the `fromDhcpListClient` function.

Trust: 0.6

sources: CNVD: CNVD-2025-27117

DESCRIPTION

A vulnerability was determined in Tenda CH22 1.0.0.1. This issue affects the function fromDhcpListClient of the file /goform/DhcpListClient. This manipulation of the argument page causes buffer overflow. Remote exploitation of the attack is possible. The exploit has been publicly disclosed and may be utilized. The Tenda CH22 is a network device manufactured by Tenda, a Chinese company. This vulnerability stems from the fact that the `page` parameter in the function `fromDhcpListClient` within the file `/goform/DhcpListClient` 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
