EUVDB-ID: #VU8847

Risk: High

CVSSv4.0: 7.4 [CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Amber]

CVE-ID: CVE-2017-13088

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 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.

Mitigation
