TitleTenda HG3 N300 Wi-Fi xPON ONT HARD_VERSION=V2.0 , Version: 300003070 dos
DescriptionA stack overflow vulnerability is present in Tenda-HG3 series IoT devices. This security flaw is triggered by the lack of parameter validity checks and insufficient input verification mechanisms, where the device fails to properly validate and restrict incoming parameters, directly leading to a stack overflow anomaly. Malicious attackers can exploit this vulnerability to gain unauthorized access to the device’s internal system interfaces, and such exploitation behavior will further cause denial-of-service (DoS) exceptions on the target IoT device, affecting its normal operation.
