Advies gebruik van Intel Wireless Adapters, bepalen juiste drivers en protocollen.

Lezers,

Op 16 oktober publiceerden Mathy Vanhoef en Frank Piessens van de Universiteit van Leuven een document waarin een reeks kwetsbaarheden wordt beschreven die de Wi-Fi Protected Access (WPA) en de Wi-Fi Protected Access II (WPA2) protocollen beïnvloeden.

Dit zijn kwetsbaarheden op protocolniveau van draadloze leveranciers en draadloze clients(adapters) die de huidige WPA- en WPA2-specificaties volgen. Deze kwetsbaarheden werden ook aangeduid als “KRACK” (Key Reinstallation AttaCK) en de details werden gepubliceerd op: https://www.krackattacks.com

De meeste wlan client adapters moeten worden geupdate om de ‘supplicant‘ te voorzien van een beveiligings update: Er zijn 10 beveiligingslekken ontdekt waarvan Intel er inmiddels twee heeft geidentificeerd en gerepareerd. De overige lekken moeten in het Operating Systeem(bv Windows) en/of door de draadloze leveranciers gerepareerd worden:

 

 

 

Intel adapter-driver fix : CVE-2017-13081 &  CVE-2017-13080

Wi-Fi Protected Access (WPA) and Wi-Fi Protected Access II (WPA2) protocols – integrity group key reinstallation during the group key handshake vulnerability : CVE ID: CVE-2017-13081

A vulnerability in the processing of the 802.11i group key handshake messages of the WPA and WPA2 protocols could allow an unauthenticated, adjacent attacker to force a supplicant to reinstall a previously used integrity group key.

The vulnerability is due to ambiguities in the processing of associated protocol messages. An attacker could exploit this vulnerability by establishing a man-in-the-middle position between supplicant and authenticator and retransmitting previously used message exchanges between supplicant and authenticator.
