TITLE

Tenda CH22 buffer overflow vulnerability

Trust: 0.6

sources: CNVD: CNVD-2025-30571

DESCRIPTION

A vulnerability was detected in Tenda CH22 1.0.0.1. Affected is the function formWrlExtraGet of the file /goform/WrlExtraGet. Performing manipulation of the argument chkHz results in buffer overflow. Remote exploitation of the attack is possible. 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 parameter chkHz in the file /goform/WrlExtraGet 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
