Some wireless access points from Cisco Systems have a vulnerability that could allow a hacker to redirect traffic outside the enterprise or potentially gain access to an entire corporate network, a security company said.
At the root of the problem is the way that new Cisco APs are added to a network, according to AirMagnet, a wireless network security company that discovered the problem and planned to report its findings Tuesday.
Existing APs broadcast information about the nearby network controller they communicate with. That way, when an enterprise hangs a new AP, that AP listens to information broadcast by other APs and knows which controller to connect to.
