Trust: 0.6

sources: CNVD: CNVD-2024-23281

DESCRIPTION

A vulnerability was found in Tenda W9 1.0.0.7(4456). It has been classified as critical. This affects the function formQosManageDouble_user. The manipulation of the argument ssidIndex leads to stack-based buffer overflow. It is possible to initiate the attack remotely. The associated identifier of this vulnerability is VDB-262131. NOTE: The vendor was contacted early about this disclosure but did not respond in any way. Tenda W9 is a wireless wall-mounted access point from China's Tenda Company. The vulnerability is caused by the fact that the parameter ssidIndex of the formQosManageDouble_user function fails to correctly verify the length of the input data. A remote attacker can exploit this vulnerability to execute arbitrary code on the system or cause a denial of service attack
