Cisco Cops to WLAN Security Flaws

Wireless LANs have long since shaken the stigma of being less secure than their wireline counterparts, but this week Cisco Systems Inc. raised and old specter by issuing an alert warning of major security flaws in some of its WLAN controllers for voice and data applications.

There are four specific vulnerabilities that Cisco identified in its Cisco Wireless LAN Controllers, Cisco Catalyst 6500 Wireless Services Modules and Cisco Catalyst 3750 Integrated Wireless LAN Controllers.

All four flaws could allow denial-of-service or privilege escalation attacks.
