Description

This security bulletin contains information about 9 secuirty vulnerabilities.


1) Key management errors (CVE-ID: CVE-2017-13077)

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.

2) Key management errors (CVE-ID: CVE-2017-13078)

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

3) Key management errors (CVE-ID: CVE-2017-13079)

The vulnerability allows an adjacent attacker to force a supplicant to reinstall a previously used integrity group 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.

4) Key management errors (CVE-ID: CVE-2017-13080)

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

The vulnerability is dubbed "KRACK" attack.

5) Key management errors (CVE-ID: CVE-2017-13081)

The vulnerability allows an adjacent attacker to force a supplicant to reinstall a previously used integrity group 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.

6) Key management errors (CVE-ID: CVE-2017-13082)

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.

7) Key management errors (CVE-ID: CVE-2017-13086)

The vulnerability allows an adjacent attacker to force a supplicant that is compliant with the 802.11z standard to reinstall a previously used TPK key.

The weakness exists in the processing of the 802.11z (Extensions to Direct-Link Setup) TDLS handshake messages due to ambiguities in the processing of associated protocol messages. An adjacent attacker can passively eavesdrop on a TDLS handshake and retransmit previously used message exchanges between supplicant and authenticator.

8) Key management errors (CVE-ID: CVE-2017-13087)

The vulnerability allows an adjacent attacker to force a supplicant that is compliant with the 802.11v standard to reinstall a previously used group key.

The weakness exists in the processing of the 802.11v (Wireless Network Management) Sleep Mode Response frames due to ambiguities in the processing of associated protocol messages. An adjacent attacker can passively eavesdrop and retransmit previously used WNM Sleep Mode Response frames.

9) Key management errors (CVE-ID: CVE-2017-13088)

The vulnerability allows an adjacent attacker to force a supplicant that is compliant with the 802.11v standard to reinstall a previously used integrity group key.

The weakness exists in the processing of the 802.11v (Wireless Network Management) Sleep Mode Response frames due to ambiguities in the processing of associated protocol messages. An adjacent attacker can passively eavesdrop and retransmit previously used WNM Sleep Mode Response frames.
