CVE-2025-15091Public exploitNetwork attack vector

Router crash via unchecked importpictureurl copy

Published Dec 25, 2025 · Updated Dec 25, 2025

Buffer overflow in Shanghai Aitai Technology 进取 512W 1.7.7-171114 and earlier allows remote authenticated users to crash the router. The /goform/formPictureUrl handler passes the importpictureurl parameter to strcpy, copying it to an internal buffer without checking its length. Administrator credentials are required by the published request; oversized input corrupts adjacent memory and can interrupt routing, while code execution has not been demonstrated.
