CVE-2022-28582Network attack vector

Unauthenticated command execution via crafted Wi-Fi settings

Published May 5, 2022 · Updated Aug 3, 2024

OS command injection in the setWiFiSignalCfg interface of TOTOlink A7100RU firmware 7.4cu.2313_b20191024 allows remote attackers to execute commands. Public records identify the interface and a crafted payload but do not disclose the affected parameter or command-construction code. Network access to the router interface is sufficient; successful exploitation runs arbitrary commands with the interface process privileges.
