CVE-2019-9494

The connected documents confirm a residual vulnerability in the SAE implementation for hostapd and wpa_supplicant: side-channel attacks via cache access patterns/timing, affecting hostapd before 2.10 and wpa_supplicant before 2.10. This is noted as stemming from an incomplete fix for CVE-2019-949...

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-2019-9496

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-2019-9499

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-2019-9496

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-2019-9497

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 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 -- 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 -- 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...
