Security Bulletin

This security bulletin contains information about 6 vulnerabilities.

1) Key management errors

EUVDB-ID: #VU8838

Risk: High

CVSSv3.1: 9.1 [CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H/E:P/RL:U/RC:C]

CVE-ID: CVE-2017-13078

CWE-ID: CWE-320 - Key Management Errors

Exploit availability: No

Description

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.

Mitigation

Update the affected packages.

Q & A

Can this vulnerability be exploited remotely?

Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the local network (LAN).

Is there known malware, which exploits this vulnerability?

No. We are not aware of malware exploiting this vulnerability. However, proof of concept for this vulnerability is available.

2) Key management errors

EUVDB-ID: #VU8839

Risk: High

CVSSv3.1: 9.1 [CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H/E:P/RL:U/RC:C]

CVE-ID: CVE-2017-13079

CWE-ID: CWE-320 - Key Management Errors

Exploit availability: No

Description

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.

5) Key management errors

EUVDB-ID: #VU8846

Risk: High

CVSSv3.1: 9.1 [CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H/E:P/RL:U/RC:C]

CVE-ID: CVE-2017-13087

CWE-ID: CWE-320 - Key Management Errors

Exploit availability: No

Description

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.

Mitigation

Update the affected packages.
