"According to its self-reported version, Cisco Wireless LAN Controller
(WLC) is affected by following vulnerability

  - Multiple vulnerabilities in the administrative GUI
    configuration feature of Cisco Wireless LAN Controller
    (WLC) Software could allow an authenticated, remote
    attacker to cause the device to reload unexpectedly
    during device configuration when the administrator is
    using this GUI, causing a denial of service (DoS)
    condition on an affected device. The attacker would need
    to have valid administrator credentials on the
    device.These vulnerabilities are due to incomplete input
    validation for unexpected configuration options that the
    attacker could submit while accessing the GUI
    configuration menus. An attacker could exploit these
    vulnerabilities by authenticating to the device and
    submitting crafted user input when using the
    administrative GUI configuration feature. A successful
    exploit could allow the attacker to cause the device to
    reload, resulting in a DoS condition.These
    vulnerabilities have a Security Impact Rating (SIR) of
    High because they could be exploited when the software
    fix for the Cisco Wireless LAN Controller Cross-Site
    Request Forgery Vulnerability [https://tools.cisco.com/
    security/center/content/CiscoSecurityAdvisory/cisco-
    sa-20190417-wlc-csrf] is not in place. In that case, an
    unauthenticated attacker who first exploits the cross-
    site request forgery vulnerability could perform
    arbitrary commands with the privileges of the
    administrator user by exploiting the vulnerabilities
    described in this advisory. (CVE-2018-0248)
