Summary

  o A vulnerability in the REST API of Cisco 5500 and 8500 Series Wireless LAN
    Controller (WLC) Software could allow an unauthenticated, remote attacker

    vulnerability by sending a malicious URL to the REST API. If successful, an
    exploit could allow the attacker to view sensitive system information.
