802.11b is the wireless protocol specification published by the IEEE. A problem in the implementation the standard could allow an arbitrary user on the wireless network to perform a man-in-the-middle attack. This attack could be launched from the wireless network, and affect any host on the wireless or wired network within the same broadcast domain. Due to the forwarding of ARP requests by Wireless Access Points, it is possible to poison the caches of systems within a broadcast domain to route traffic intended for a specific host through an arbitrary host. This makes it possible for an attacker with access to the wireless network to monitor network traffic, and potentially gain access to sensitive information or systems.
