Wi-Fi Protected Access (WPA) handshake traffic can be manipulated to induce nonce and session key reuse

Vulnerability Note VU#228519

Original Release Date: 2017-10-16 | Last Revised: 2017-11-16

Overview

Wi-Fi Protected Access (WPA, more commonly WPA2) handshake traffic can be manipulated to induce nonce and session key reuse, resulting in key reinstallation by a wireless access point (AP) or client. An attacker within range of an affected AP and client may leverage these vulnerabilities to conduct attacks that are dependent on the data confidentiality protocols being used. Attacks may include arbitrary packet decryption and injection, TCP connection hijacking, HTTP content injection, or the replay of unicast and group-addressed frames. These vulnerabilities are referred to as Key Reinstallation Attacks or "KRACK" attacks.

Description

CWE-323: Reusing a Nonce, Key Pair in Encryption

Wi-Fi Protected Access II (WPA2) handshake traffic can be manipulated to induce nonce and session key reuse, resulting in key reinstallation by a victim wireless access point (AP) or client. After establishing a man-in-the-middle position between an AP and client, an attacker can selectively manipulate the timing and transmission of messages in the WPA2 Four-way, Group Key, Fast Basic Service Set (BSS) Transition, PeerKey, Tunneled Direct-Link Setup (TDLS) PeerKey (TPK), or Wireless Network Management (WNM) Sleep Mode handshakes, resulting in out-of-sequence reception or retransmission of messages. Depending on the data confidentiality protocols in use (e.g. TKIP, CCMP, and GCMP) and situational factors, the effect of these manipulations is to reset nonces and replay counters and ultimately to reinstall session keys. Key reuse facilitates arbitrary packet decryption and injection, TCP connection hijacking, HTTP content injection, or the replay of unicast, broadcast, and multicast frames.

The following CVE IDs have been assigned to document these vulnerabilities in the WPA2 protocol:

    • CVE-2017-13077: reinstallation of the pairwise key in the Four-way handshake
    • CVE-2017-13078: reinstallation of the group key in the Four-way handshake
    • CVE-2017-13079: reinstallation of the integrity group key in the Four-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 Fast BSS Transition Reassociation 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

For a detailed description of these issues, refer to the researcher's website and paper.

Impact

An attacker within the wireless communications range of an affected AP and client may leverage these vulnerabilities to conduct attacks that are dependent on the data confidentiality protocol being used. Impacts may include arbitrary packet decryption and injection, TCP connection hijacking, HTTP content injection, or the replay of unicast, broadcast, and multicast frames.

Solution

10/18/2017 Security advisory for the vulnerabilities of WPA2 protocol

ASUS is aware of the recent WPA2 vulnerability issue. We take your security and privacy seriously and are currently working towards a full solution as quickly as possible. In the meantime, we want to help clarify the severity of the potential threat, and let our valued customers know the appropriate steps to take in order to avoid or lessen the threat of being compromised.

Your devices are only vulnerable if an attacker is in physical proximity to your wireless network and is able to gain access to it. This exploit cannot steal your banking information, passwords, or other data on a secured connection that utilizes proper end-to-end encryption. However, an attacker could capture and read this information on an unsecured connection via an exploited WiFi network. Depending on the network configuration, it is also possible for the attacker to redirect network traffic, send invalid data to devices or even inject malware into the network.

We are feverishly working with chipset suppliers to resolve this vulnerability and will release patched firmware for affected routers in the near future. Before this patched firmware is released, here are a few cautions all users should take:

(1) Avoid public Wi-Fi and Hotspots until the routers and your devices are updated. Use cellular network connections if possible.
(2) Only connect to secured services that you trust or have been verified. Web pages that use HTTPS or another secure connection will include HTTPS in the URL. If the connection is secured using TLS 1.2 your activities with that service is safe for now.
(3) Keep your operating system and antivirus software up-to-date. Microsoft recently updated Windows to fix this exploit on their latest operating systems. Google and Apple are following suit shortly.
(4) When in doubt, be safe and use your cellular network or a wired connection (Ethernet) to access the internet. This exploit only affects 802.11 traffic between a Wi-Fi router and a connected device on an exploited WiFi connection.

Vendor Statement

On October 16th, 2017, a research paper with the title of "Key Reinstallation Attacks: Forcing Nonce Reuse in WPA2" was made publicly available. This paper discusses seven vulnerabilities affecting session key negotiation in both the Wi-Fi Protected Access (WPA) and the Wi-Fi Protected Access II (WPA2) protocols. These vulnerabilities may allow the reinstallation of a pairwise transient key, a group key, or an integrity key on either a wireless client or a wireless access point. Additional research also led to the discovery of three additional vulnerabilities (not discussed in the original paper) affecting wireless supplicant supporting either the 802.11z (Extensions to Direct-Link Setup) standard or the 802.11v (Wireless Network Management) standard. The three additional vulnerabilities could also allow the reinstallation of a pairwise key, group key, or integrity group key.

Statement Date:   October 18, 2017

Status

Vendor Statement

By making use of a model-based approach, researchers from K.U Leuven University have identified several theoretical flaws in the Wi-Fi Protected Acess (WPA) protocol. These weaknesses constitute a new class of attack on the 4-way handshake used in all flavors of WPA/WPA2, named KRACK: Key Reinstallation AttaCK.

This academic research presents an industry-wide issue as all products implementing Wi-Fi are theoretically vulnerable.

In practice, no gateway or modem manufactured by Technicolor, implementing WiFi Access point routing function is affected by this class of attack. This is due to the fact that the vulnerable function allowing practical attack against the Access Point is not present. The end users should continue to use their Technicolor gateway or modem without changing WPA2 settings. In particular, none of these attacks is able to retrieve the WPA private passphrase. This recommendation is also valid for the legacy Thomson and Cisco branded gateways and modems.

The 802.11r standard makes use of a 4-way handshake protocol that was mathematically proven secure by the scientific community. Yet, the research publication exhibits weaknesses in some implementations of this protocol, that can affect the way the client connects to the Access point. For Access Points, the operational impact is very limited. Gateways and modems configured as Wi-Fi Access Point are not potentially concerned, except when supporting Fast BSS Transition handshake introduced with 802.11r standard. Fast BSS Transition handshake is usually not supported on residential gateways and modems, because this feature is intended to minimize roaming time between several access points in a managed network.

Technicolor works constantly to improve security of its products, alongside with the Wi-Fi Alliance. Technicolor remains committed to provide efficient support to its customers and end-users.

Our detailed security bulletins remain reserved for our customers. Customers can contact their Technicolor Customer Technical Support.

Vendor Statement

On October 16. CERT/CC/ICASI released a public announcement about discovered vulnerabilities in WPA2 handshake protocols that affect most WiFi users and all vendors world wide.

RouterOS v6.39.3, v6.40.4, v6.41rc are not affected!
It is important to note that the vulnerability is discovered in the protocol itself, so even a correct implementation is affected.
These organizations did contact us earlier, so we have already released fixed versions that address the outlined issues. Not all of the discovered vulnerabilities directly impact RouterOS users, or even apply to RouterOS, but we did follow all recommendations and improved the key exchange process according to the guidelines we received from the organizations who discovered the issue.
We released fixed versions last week, so if you upgrade your devices routinely, no further action is required.
CWE-323
CVE-2017-13077
CVE-2017-13078
CVE-2017-13079
CVE-2017-13080
CVE-2017-13081
CVE-2017-13082
CVE-2017-13083
CVE-2017-13084
CVE-2017-13085
CVE-2017-13086
CVE-2017-13087

The following applies to RouterOS software prior to updates related to the issue.

nv2
nv2 is not affected in any way. This applies to both - nv2 AP and client. There is no nonce reset in key exchange possible and key re-installation is not possible, because nv2 key exchange does not directly follow 802.11 key exchange specification.

802.11 nonce reuse
RouterOS is not affected in any way, RouterOS generates cryptographically strong random initial nonce on boot and never reuses the same nonce during uptime.

802.11 key reinstallation
The device operating as client in key exchange is affected by this issue. This means that RouterOS in station modes and APs that establish WDS links with other APs are affected. RouterOS APs (both - standalone and CAPsMAN controlled), that do not establish WDS links with other APs, are not affected. Key reinstallation by resending key exchange frame allows attacker to reset encrypted frame packet counter. This allows attacker to replay frames that where previously sent by AP to client. Please note that RouterOS DOES NOT reset key to some known value that would allow attacker to inject/decrypt any frames to/from client.

Suggested course of action
It is always recommended to upgrade to latest RouterOS version, but depending on wireless protocol and mode the suggested course of action is as follows:
- nv2: no action necessary
- 802.11/nstreme AP without WDS: no action necessary
- CAPsMAN: no action necessary
- 802.11/nstreme client (all station modes) or AP with WDS: upgrade to fixed version ASAP.

Vendor Information

Though Mikrotik has self-identified as not affected, they have published updates that "improved WPA2 key exchange reliability" (see https://mikrotik.com/download/changelogs).
