Cisco Addresses Wi-Fi Security Issues

A host of wireless vulnerabilities have been patched in several Cisco devices, the company revealed Thursday in two separate advisories. The first exists within its Wireless Control System, and works in conjunction with Cisco Aironet Lightweight Access Points, Cisco Wireless LAN Controllers, and the Cisco Wireless Location Appliance, it said in an advisory. Among the risks are information disclosure, privilege escalation, and unauthorized access, it said in the advisory.

The second fix addresses multiple problems in Cisco's Wireless LAN Controllers and Lightweight Access Points. There an attacker could cause a denial-of-service, disclose private information, change access control lists, or gain full control of the network. Those owning either product are urged to apply the patches immediately, Cisco says.
