CVE-2022-46631Network attack vector

Unauthenticated command execution via wscDisabled injection

Published Dec 15, 2022 · Updated Apr 21, 2025

OS command injection in TOTOlink A7100RU firmware 7.4cu.2313_B20191024 allows remote attackers to execute commands via wscDisabled. The setting/setWiFiSignalCfg function incorporates the parameter into an operating-system command without neutralizing command syntax. The network path requires no privileges or user interaction, and successful exploitation grants control over firmware execution.
