Unauthenticated code execution via unbounded page copy
Published Dec 22, 2025 · Updated Dec 22, 2025
Stack-based buffer overflow in Tenda WH450 1.0.0.18 allows remote attackers to execute code or crash the router via a crafted HTTP request. The /goform/L7Port handler accepts a page value longer than its 64-byte stack buffer without enforcing a length bound, and op=0 reaches the vulnerable path. No authentication or user interaction is required, and successful exploitation permits code execution or a service-interrupting crash.
