Buffer overflow vulnerability exists in FutureNet AS series (Industrial Routers) and FA series (Protocol Conversion Machine) provided by Century Systems Co., Ltd. If this vulnerability is exploited, a remote unauthenticated attacker may reboot the device by sending a specially crafted request.
The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow.
