CVE-2023-24126Network attack vector

Authenticated router crash via oversized Wi-Fi key

Published Mar 1, 2023 · Updated Jul 9, 2026

Stack-based overflow in Eagle 1200AC 15.03.06.33_en allows remote authenticated users to crash the router via a crafted Wi-Fi key. The /goform/WifiBasicSet handler processes an oversized wepkey4_5g parameter without enforcing the destination stack buffer's bounds. A valid low-privilege session is required; the bounded consequence is a router crash and resulting service interruption, with no reported data exposure or modification.
