Problem Description:

When using WPA2, EAPOL-Key frames with the Encrypted + flag and without the MIC flag set, the data field was + decrypted first without verifying the MIC. When the dta + field was encrypted using RC4, for example, when negotiating + TKIP as a pairwise cipher, the unauthenticated but decrypted + data was subsequently processed. This opened wpa_supplicant(8) + to abuse by decryption and recovery of sensitive information + contained in EAPOL-Key messages.

See + https://w1.fi/security/2018-1/unauthenticated-eapol-key-decryption.txt + for a detailed description of the bug.

Impact:

All users of the WPA2 TKIP pairwise cipher are vulnerable + to information, for example, the group key.
