One or more Intel Products affected by the Wi-Fi Protected Access II (WPA2) protocol vulnerability

Intel ID:  INTEL-SA-00101
Product family:  Various
Impact of vulnerability Information Disclosure
Severity rating Important
Original release:  Oct 16, 2017
Last revised:  Nov 16, 2017
Summary: 

Researchers Mathy Vanhoef and Frank Piessens, from the University of Leuven, identified a series of vulnerabilities that affect the Wi-Fi Protected Access (WPA) and Wi-Fi Protected Access II (WPA2) standards.

Description: 

These vulnerabilities are protocol-level vulnerabilities that affect a number of industry implementations of the standard in wireless infrastructure devices and wireless clients. The paper is available through the following link: https://papers.mathyvanhoef.com/ccs2017.pdf

An attacker within range of an affected wireless access point (AP) and client may leverage these vulnerabilities to conduct attacks using susceptible data confidentiality protocols.

The following Common Vulnerability and Exposure (CVE) identifiers have been assigned to each of these vulnerabilities:

CVE-2017-13077 reinstallation of the pairwise key in the 4-way handshake
 
CVE-2017-13078 reinstallation of the group key in the 4-way handshake
 
CVE-2017-13079 reinstallation of the integrity group key in the 4-way handshake
 
CVE-2017-13080 reinstallation of the group key in the group key handshake
 
CVE-2017-13081 reinstallation of the integrity group key in the group key handshake

CVE-2017-13082 Accepting a retransmitted FT Re-association Request and reinstalling the pairwise key while processing it
 
CVE-2017-13084 reinstallation of the STK key in the PeerKey handshake
 
CVE-2017-13086 Reinstallation of the Tunneled Direct-Link Setup (TDLS) PeerKey (TPK) key in the TDLS handshake
 
CVE-2017-13087 Reinstallation of the group key (GTK) when processing a Wireless Network Management (WNM) Sleep Mode Response frame

CVE-2017-13088 Reinstallation of the integrity group key (IGTK) when processing a Wireless Network Management (WNM) Sleep Mode Response frame
  

These vulnerabilities can be grouped into two categories: those that affect wireless endpoints acting as a “supplicant” and those that affect wireless infrastructure devices acting as "authenticators". Successful exploitation of these vulnerabilities could, depending on the specific device configuration, allow unauthenticated attackers to perform packet replays, decrypt wireless packets, and potentially forge or inject packets into a wireless network. The attacks manipulate retransmissions of handshake messages.

• Intel is targeting an updated firmware release to System Manufacturers in early November 2017 to address the identified WPA2 vulnerabilities.  Please contact System Manufacturers to ascertain availability of the updated firmware for their impacted systems.

• Until the firmware update is deployed, configuring Active Management Technology in TLS Mode to encrypt manageability network traffic is considered a reasonable mitigation for remote network man-in-the-middle or eavesdropping attacks. See  Section 5.10 "Defining Transport Layer Security (TLS)" in the Intel® Setup and Configuration Software (Intel® SCS) Users Guide for details

* For Intel® Active Management Technology, there is no planned Intel® Manageability Engine firmware update for versions 2.x-7.x because those versions are no longer supported.

For WIND™ (Wind River) Products, please visit this page

For the following Intel® Centrino® Wireless adapters there is no planned software update because those products were end-of-life’d in 2014 and 2015. Disabling the Wake-on-Wireless-LAN functionality (WoWLAN), is a reasonable mitigation against CVE-2017-13080 and CVE-2017-13081. For more information about disabling WoWLAN, please see this support page.
 
Intel® Centrino® Wireless adapters not listed have an end-of-Life date earlier than 2014. The mitigation described above has not been validated with the adapters end-of-Life’d earlier than 2014.

Wireless Adapter Product
