CVE-2016-1364
CWE-399
Summary
A vulnerability in the Bonjour task manager of Cisco Wireless LAN
Controller (WLC) Software could allow an unauthenticated, remote attacker
to cause a denial of service (DoS) condition on an affected device.
The vulnerability is due to improper handling of Bonjour traffic by
the affected software. An attacker could exploit this vulnerability by
sending crafted Bonjour traffic to an affected device. A successful
exploit could allow the attacker to cause the device to reload,
resulting in a DoS condition.
Cisco has released software updates that address this
vulnerability. There are no workarounds that address this vulnerability.

CWE-399
Summary
A vulnerability in the web-based management interface of Cisco Wireless
LAN Controller (WLC) devices running Cisco AireOS Software could allow
an unauthenticated, remote attacker to cause an affected device to
reload, resulting in a denial of service (DoS) condition.
The vulnerability is due to the presence of unsupported URLs in
the web-based device management interface provided by the affected
software. An attacker could exploit this vulnerability by attempting
to access a URL that is not generally accessible from and supported
by the management interface. A successful exploit could allow the
attacker to cause the device to reload, resulting in a DoS condition.
Cisco has released software updates that address this
vulnerability. There is a workaround that addresses this vulnerability.
