Cisco Fixes Wireless LAN Controller Flaws

Cisco Systems has released security updates to fix vulnerabilities found in its Wireless LAN Controller (WLC) and Wireless Services Module (WiSM) devices.

According to tech news site Softpedia, the software update has managed to fix all of the seven bugs reported last week, out of which two are DoS vulnerabilities, three privilege vulnerabilities and two are ACL bypass holes.

"These devices communicate with controller-based access points over any Layer 2 (Ethernet) or Layer 3 (IP) infrastructure using the Lightweight Access Point Protocol (LWAPP) and the Control and Provisioning of Wireless Access Points (CAPWAP) protocol," explained Cisco in the wireless LAN controllers advisory.

Cisco has updated its advisory with list of WLC software versions, along with vulnerabilities that can be exploited to harm the system.

Users can get the updated software from Cisco's website or any third party agency, depending on user's service contracts.
