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.
