| 标题 | Tenda RX3 V16.03.13.11 Stack-based Buffer Overflow |
|---|
| 描述 | During a security review of the Tenda RX3 router firmware (version V16.03.13.11), a critical stack-based buffer overflow vulnerability was identified in the QoS (Quality of Service) configuration endpoint /goform/formSetQosBand.
The vulnerability is located in the set_qosMib_list function, which is called by the request handler formSetQosBand. The function receives a user-controlled list parameter. It searches for a delimiter and then uses the unsafe strcpy function to copy the contents of the list into a fixed-size stack buffer qos_str (256 bytes). Since the input length is not validated, an attacker can overwrite the stack frame, leading to a Denial of Service (DoS) or arbitrary code execution. |
