Summary

  o A vulnerability in the default configuration of the Cisco Aironet Active
    Sensor could allow an unauthenticated, remote attacker to restart the
    sensor.

    The vulnerability is due to a default local account with a static password.
    The account has privileges only to reboot the device. An attacker could
    exploit this vulnerability by guessing the account name and password to
    access the CLI. A successful exploit could allow the attacker to reboot the
    device repeatedly, creating a denial of service (DoS) condition. It is not
    possible to change the configuration or view sensitive data with this
    account.

    There are no workarounds that address this vulnerability.
