CVE-2017-13088

Status Candidate

Overview

Wi-Fi Protected Access (WPA and WPA2) that support 802.11v allows reinstallation of the Integrity Group Temporal Key (IGTK) when processing a Wireless Network Management (WNM) Sleep Mode Response frame, allowing an attacker within radio range to replay frames from access points to clients.

FreeBSD Security Advisory - FreeBSD-SA-17:07.wpa
Posted Oct 19, 2017
Authored by Mathy Vanhoef | Site security.freebsd.org

FreeBSD Security Advisory - A vulnerability was found in how a number of implementations can be triggered to reconfigure WPA/WPA2/RSN keys (TK, GTK, or IGTK) by replaying a specific frame that is used to manage the keys. Such reinstallation of the encryption key can result in two different types of vulnerabilities: disabling replay protection and significantly reducing the security of encryption to the point of allowing frames to be decrypted or some parts of the keys to be determined by an attacker depending on which cipher is used.

Red Hat Security Advisory 2017-2907-01
Posted Oct 17, 2017
Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2017-2907-01 - The wpa_supplicant packages contain an 802.1X Supplicant with support for WEP, WPA, WPA2, and various EAP authentication methods. They implement key negotiation with a WPA Authenticator for client stations and controls the roaming and IEEE 802.11 authentication and association of the WLAN driver. Security Fix: A new exploitation technique called key reinstallation attacks affecting WPA2 has been discovered. A remote attacker within Wi-Fi range could exploit these attacks to decrypt Wi-Fi traffic or possibly inject forged Wi-Fi packets by manipulating cryptographic handshakes used by the WPA2 protocol.

Ubuntu Security Notice USN-3455-1
Posted Oct 16, 2017
Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 3455-1 - Mathy Vanhoef discovered that wpa_supplicant and hostapd incorrectly handled WPA2. A remote attacker could use this issue with using key reinstallation attacks to obtain sensitive information. Imre Rad discovered that wpa_supplicant and hostapd incorrectly handled invalid characters in passphrase parameters. A remote attacker could use this issue to cause a denial of service. Various other issues were also addressed.

Debian Security Advisory 3999-1
Posted Oct 16, 2017
Authored by Debian | Site debian.org

Debian Linux Security Advisory 3999-1 - Mathy Vanhoef of the imec-DistriNet research group of KU Leuven discovered multiple vulnerabilities in the WPA protocol, used for authentication in wireless networks. Those vulnerabilities applies to both the access point (implemented in hostapd) and the station (implemented in wpa_supplicant).

Key Reinstallation: Forcing Nonce Reuse In WPA2
Posted Oct 16, 2017
Authored by Frank Piessens, Mathy Vanhoef | Site krackattacks.com

Whitepaper called Reinstallation Attacks: Forcing Nonce Reuse in WPA2. This research paper will be presented on at the Computer and Communications Security (CCS) conference on November 1, 2017. This paper details a flaw in the WPA2 protocol itself and most devices that makes use of WPA2 are affected.
