Summary

  o A vulnerability in the Cisco Connected Mobile Experiences (CMX) software
    could allow an unauthenticated, adjacent attacker to access sensitive data
    on an affected device.

    The vulnerability is due to a lack of input and validation checking
    mechanisms for certain GET requests to API's on an affected device. An
    attacker could exploit this vulnerability by sending HTTP GET requests to
    an affected device. An exploit could allow the attacker to use this
    information to conduct additional reconnaissance attacks.
