CVE-2022-45501Public exploitNetwork attack vector

Unauthenticated router crash via unchecked index

Published Dec 8, 2022 · Updated Apr 23, 2025

Stack overflow in Tenda W6-S v1.0.0.4(510) allows remote attackers to cause a service interrupt via the wl_radio parameter. The /goform/wifiSSIDset handler concatenates attacker-controlled index data into v24 with sprintf when wl_radio is 0, without a size check, overflowing the stack. A reachable HTTP interface is sufficient; the published proof of concept crashes the router, and the report claims that subsequent exploitation can obtain a root shell.
