CVE-2023-24121Public exploitNetwork attack vector

Authenticated router crash via oversized security parameter

Published Mar 1, 2023 · Updated Jul 9, 2026

Stack overflow in Eagle 1200AC firmware 15.03.06.33_en allows remote authenticated users to crash the router via a crafted request. The /goform/WifiBasicSet handler processes an oversized security_5g value without enforcing the destination stack buffer's bounds, overwriting adjacent stack memory. Valid management credentials and network access to the web interface are required; exploitation interrupts router availability without reported data disclosure or modification.
