W9 V1.0.0.7(4456)
In the W9 V1.0.0.7(4456) firmware has a stack overflow vulnerability in the formQosManageDouble_auto function. The index variable receives the ssidIndex parameter from a POST request. However, since the user can control the input of ssidIndex, the statement sprintf(mib_prefix_wl2g, "wl2g.ssid%s.", index); can cause a buffer overflow. The user-provided ssidIndex can exceed the capacity of the mib_prefix_wl2g array, triggering this security vulnerability.
