In short

The UTT 进取 512W router has a buffer overflow vulnerability in its network configuration function that allows attackers to send malicious data remotely, potentially taking complete control of the device.

Technical detail

A stack-based buffer overflow exists in the /goform/formNatStaticMap endpoint due to unsafe strcpy usage (CWE-120). Remote attackers can exploit the NatBind parameter without authentication to overflow a fixed-size buffer, achieving arbitrary code execution with device privileges. The vulnerability affects versions up to 3.1.7.7-171114.
