CVE-2025-10392Public exploitNetwork attack vector

Service crash via oversized Host header

Published Sep 14, 2025 · Updated Sep 15, 2025

Stack-based buffer overflow in Mercury KM08-708H GiGA WiFi Wave2 1.1.14 allows remote attackers to crash services via the Host header. The undisclosed HTTP Header Handler function fails to bound attacker-controlled Host header data before it reaches a stack buffer. No authentication or user interaction is required, and public evidence demonstrates a service crash but does not establish code execution.
