CVE-2022-3713

Adjacent code execution via Wi-Fi controller injection

Published Dec 1, 2022 · Updated Apr 24, 2025

Code injection in the Sophos Firewall Wi-Fi controller allows adjacent attackers to execute code on affected pre-fix releases. Sophos has not published the controller locus or the untrusted input and unsafe code-generation operation that enable injection. Access requires connection to an interface with Wireless Protection enabled; successful exploitation runs attacker-supplied code in the controller.
