CVE-2024-30593Network attack vector

Remote compromise via deviceName stack overflow

Published Mar 28, 2024 · Updated Apr 10, 2025

Stack overflow in Tenda FH1202 1.2.0.14(408) allows remote attackers to compromise the router via a crafted deviceName value. The flaw resides in formSetDeviceName at /goform/SetOnlineDevName, where oversized deviceName input reaches a stack buffer; the deleted disclosure no longer reveals the exact unchecked copy operation. Network reachability is sufficient, with no authentication or user interaction required, and successful exploitation grants total control of the affected router firmware.
