Description

The vulnerability allows an adjacent attacker to force a supplicant to reinstall a previously used pairwise key.

The weakness exists in the processing of the 802.11i 4-way handshake messages of the WPA and WPA2 protocols due to ambiguities in the processing of associated protocol messages. An adjacent attacker can use man-in-the-middle techniques to retransmit previously used message exchanges between supplicant and authenticator.
