CVE-2025-34149Public exploit

Unauthenticated root command execution via WPA2 key

Published Aug 7, 2025 · Updated Dec 1, 2025

OS command injection in the M300 Wi-Fi Repeater allows remote attackers to execute commands as root through wireless WPA2 setup. The wisp_conf handler inserts the untrusted key parameter into a UCI command with sprintf and passes it to doSystemCmdComlib for shell execution. No authentication is required, but the management endpoint must be reachable over the adjacent wireless network; successful requests run with root privileges and trigger a device reboot.
