TITLE

Tenda CH22 fromSafeUrlFilter function buffer overflow vulnerability

Trust: 0.6

sources: CNVD: CNVD-2025-27234

DESCRIPTION

A flaw has been found in Tenda CH22 1.0.0.1. Affected by this issue is the function fromSafeUrlFilter of the file /goform/SafeUrlFilter. Executing manipulation of the argument page can lead to buffer overflow. The attack can be launched remotely. The exploit has been published and may be used. 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 `page` parameter of the function `fromSafeUrlFilter` in the file `/goform/SafeUrlFilter` 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
