A feature of Cisco's Aironet 1200 Series Access Point can be abused by hackers to gain access to a company network, claim researchers from Core Security Technologies. The device is usually used to power wireless LANs, and has the option of being set to a WPA migration mode, in order to allow companies to gradually migrate from using the insecure WEP encryption to using the more secure WPA standard without having to upgrade the equipment all at once. If this migration mode is not disabled after the migration is complete, the network is as insecure as it was before when WEP devices were used, since the researchers managed to crack the network encryption key by forcing the device to send out WEP broadcast packets.
