CVE-2019-9496: External Control of Critical State Data

An invalid authentication sequence could result in the hostapd process terminating due to missing state validation steps when processing the SAE confirm message when in hostapd/AP mode. All version of hostapd with SAE support are vulnerable. An attacker may force the hostapd process to terminate,...

CVE-2019-9494: Observable Timing Discrepancy

The implementations of SAE in hostapd and wpasupplicant are vulnerable to side channel attacks as a result of observable timing differences and cache access patterns. An attacker may be able to gain leaked information from a side channel attack that can be used for full password recovery. Both...

Vulnerabilities in the WPA3 Wi-Fi Security Protocol

Researchers have found several vulnerabilities in the WPA3 Wi-Fi security protocol: The design flaws we discovered can be divided in two categories. The first category consists of downgrade attacks against WPA3-capable devices, and the second category consists of weaknesses in the Dragonfly...

Debian DSA-4430-1 : wpa - security update

Mathy Vanhoef NYUAD and Eyal Ronen Tel Aviv University & KU Leuven found multiple vulnerabilities in the WPA implementation found in wpasupplication station and hostapd access point. These vulnerability are also collectively known as 'Dragonblood'. - CVE-2019-9495 Cache-based side-channel attack...

WPA3 design issues and implementation vulnerabilities in hostapd and wpa_supplicant

Overview Multiple vulnerabilities have been identified in WPA3 protocol design and implementations of hostapd and wpasupplicant, which can allow a remote attacker to acquire a weak password, conduct a denial of service, or gain complete authorization. These vulnerabilities have also been referred...

CVE-2019-9499

The implementations of EAP-PWD in wpasupplicant EAP Peer, when built against a crypto library missing explicit validation on imported elements, do not validate the scalar and element values in EAP-pwd-Commit. An attacker may complete authentication, session key and control of the data connection...

CVE-2019-9494

The implementations of SAE in hostapd and wpasupplicant are vulnerable to side channel attacks as a result of observable timing differences and cache access patterns. An attacker may be able to gain leaked information from a side channel attack that can be used for full password recovery. Both...

CVE-2019-9497

The implementations of EAP-PWD in hostapd EAP Server and wpasupplicant EAP Peer do not validate the scalar and element values in EAP-pwd-Commit. This vulnerability may allow an attacker to complete EAP-PWD authentication without knowing the password. However, unless the crypto library does not...

FreeBSD -- SAE confirm missing state validation

Problem Description: When hostapd is used to operate an access point with SAE Simultaneous Authentication of Equals; also known as WPA3-Personal, an invalid authentication sequence could result in the hostapd process terminating due to a NULL pointer dereference when processing SAE confirm messag...

FreeBSD -- SAE side-channel attacks

Problem Description: Side channel attacks in the SAE implementations used by both hostapd AP and wpasupplicant infrastructure BSS station/mesh station. SAE Simultaneous Authentication of Equals is also known as WPA3-Personal. The discovered side channel attacks may be able to leak information abo...

FreeBSD -- EAP-pwd side-channel attack

Problem Description: Potential side channel attacks in the SAE implementations used by both hostapd and wpasupplicant see CVE-2019-9494 and VU871675. EAP-pwd uses a similar design for deriving PWE from the password and while a specific attack against EAP-pwd is not yet known to be tested, there i...

New APIs Suggest WPA3 Wi-Fi Security Support Coming Soon to Windows 10

Windows 10 users don't have to wait much longer for the support of latest WPA3 Wi-Fi security standard, a new blog post from Microsoft apparently revealed. The third version of Wi-Fi Protected Access, in-short WPA3, is the next generation of the wireless security protocol that has been designed t...

WPA3 Standard Officially Launches With New Wi-Fi Security Features

The Wi-Fi Alliance today officially launched WPA3—the next-generation Wi-Fi security standard that promises to eliminate all the known security vulnerabilities and wireless attacks that are up today including the dangerous KRACK attacks. WPA, or Wi-Fi Protected Access, is a standard designed to...

Input validation

A vulnerability in the General Packet Radio Service GPRS Tunneling Protocol ingress packet handler of Cisco ASR 5500 System Architecture Evolution SAE Gateways could allow an unauthenticated, remote attacker to cause a partial denial of service DoS condition on an affected device. The vulnerabili...
