CVE-2025-15044Public exploitNetwork attack vector

Unauthenticated code execution via unchecked page parameter

Published Dec 23, 2025 · Updated Dec 23, 2025

Stack-based buffer overflow in Tenda WH450 1.0.0.18 allows remote attackers to execute code or crash the router via the page parameter. The NatStaticSetting handler combines the fixed nat_static.asp?page= prefix with attacker-controlled data in a 256-byte stack buffer without enforcing the combined length. Unauthenticated HTTP reachability is sufficient; successful exploitation permits router compromise or a service crash.
