DESCRIPTION:
Multiple vulnerabilities have been reported in Cisco Wireless Lan
Controllers, which can be exploited by malicious users to bypass
certain security restrictions and compromise a vulnerable system and
by malicious people to cause a DoS (Denial of Service).

1) An error within the wIPS component when handling certain IP
packets can be exploited to cause a reload.

Successful exploitation requires that Cisco WLCs are configured with
Wireless Intrusion Prevention System (wIPS).

2) An error when handling certain Session Initiation Protocol (SIP)
packets can be exploited to cause a reload.

This vulnerability affects Cisco Wireless LAN Controller-managed
Cisco Wireless Access Points (APs) only.

3) An input sanitisation error can be exploited to execute arbitrary
code by sending a specially crafted UserAgent string.

4) An error when handling access restrictions can be exploited to
view or modify sensitive information such as configuration files.

The vulnerabilities are reported in the following products:
* Cisco 2000 Series WLC
* Cisco 2100 Series WLC
* Cisco 2500 Series WLC
* Cisco 4100 Series WLC
* Cisco 4400 Series WLC
* Cisco 5500 Series WLC
* Cisco 7500 Series WLC
* Cisco 8500 Series WLC
* Cisco 500 Series Wireless Express Mobility Controllers
* Cisco Wireless Services Module (Cisco WiSM)
* Cisco Wireless Services Module version 2 (Cisco WiSM version 2)
* Cisco NME-AIR-WLC Module for Integrated Services Routers (ISRs)
* Cisco NM-AIR-WLC Module for Integrated Services Routers (ISRs)
* Cisco Catalyst 3750G Integrated WLCs
* Cisco Flex 7500 Series Cloud Controller
* Cisco Virtual Wireless Controller
