CVE-2026-2904Public exploitNetwork attack vector

Authenticated service interruption via unchecked indexIDNew copy

Published Feb 22, 2026 · Updated Feb 22, 2026

Buffer overflow in Shanghai Aitai HiPER 810G 1.7.7-171114 allows remote authenticated users to interrupt gateway service. The /goform/ConfigExceptAli handler copies an attacker-controlled indexIDNew value into str_ with strcpy without checking its length. A valid management session is required; a crafted POST corrupts memory and interrupts routing, while code execution has not been demonstrated.
