CVE-2025-44890Public exploitNetwork attack vector

Unauthenticated memory corruption via oversized host_ip parameter

Published May 20, 2025 · Updated May 21, 2025

Stack-based buffer overflow in PLANET FW-WGS-804HPT 1.305b241111 allows remote attackers to corrupt memory via a crafted host_ip value. The web_snmp_notifyv3_add_post handler fails to enforce the destination stack buffer's capacity when it processes host_ip input. No authentication or user interaction is required, and successful exploitation can corrupt process memory and interrupt switch management.
