TITLE

Tenda CH22 buffer overflow vulnerability in the fromSafeClientFilter function

Trust: 0.6

sources: CNVD: CNVD-2025-27441

DESCRIPTION

A vulnerability was detected in Tenda CH22 1.0.0.1. Affected by this vulnerability is the function fromSafeClientFilter of the file /goform/SafeClientFilter. Performing manipulation of the argument page results in buffer overflow. The attack can be initiated remotely. The exploit is now public and may be used. The Tenda CH22 is a network device manufactured by Tenda, a Chinese company. This vulnerability stems from the fact that the `page` parameter of the function `fromSafeClientFilter` in the file `/goform/SafeClientFilter` 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
