Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
EUVDB-ID: #VU8840
Risk: Medium
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-2017-13080
CWE-ID:
CWE-320 - Key Management Errors
Exploit availability: No
DescriptionThe 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.
