CVE-2025-34150Public exploit

Root command execution via PPPoE username interpolation

Published Aug 7, 2025 · Updated Dec 1, 2025

OS command injection in the M300 Wi-Fi Repeater allows remote attackers on an adjacent network to execute commands as root through PPPoE setup. The protocol.csp wisp_conf handler interpolates the user parameter without neutralization into a uci set network.wan.username shell command passed to doSystemCmdComlib(). The management endpoint requires no authentication, but exploitation requires network reachability to the device and applying the PPPoE configuration triggers a reboot after the injected command runs.
