CVE-2025-14878Public exploitNetwork attack vector

Unauthenticated code execution via unchecked GO concatenation

Published Dec 18, 2025 · Updated Dec 18, 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 wirelessRestart handler copies a fixed path into a 64-byte stack buffer and appends the unbounded GO value without checking the remaining space. No credentials or user interaction are required; an oversized value can corrupt the stack, redirect control flow, or interrupt service.
