Authenticated router crash via oversized WEP key

Published Mar 1, 2023 · Updated Jul 9, 2026

Stack overflow in Jensen of Scandinavia Eagle 1200AC 15.03.06.33_en allows remote authenticated users to crash the router. The /goform/WifiBasicSet handler processes an oversized wepkey4 value without sufficient bounds checking, causing a write beyond its stack buffer. Access to the authenticated Wi-Fi configuration interface is required; exploitation interrupts availability without reported data disclosure or modification.
