CVE-2025-11355Network attack vector

Authenticated memory corruption via unchecked pvid copy

Published Oct 7, 2025 · Updated Oct 7, 2025

Stack buffer overflow in Shanghai Aitai HiPER 1250GW v2v3.2.2-200710 allows remote authenticated users to corrupt memory via pvid. The /goform/aspChangeChannel handler passes the attacker-controlled pvid value to strcpy without checking the destination buffer's capacity. A valid management session is required, and the documented consequence is memory corruption; reliable code execution or only a crash is not established.
