CERT continues to review the WPA3 protocol in support of this body of research. The root cause of the numerous"implementation"vulnerabilities may involve modifying the protocol. WPA3 uses Simultaneous Authentication of Equals(SAE),also known as Dragonfly Key Exchange,as the initial key exchange protocol,replacing WPA2's Pre-Shared Key(PSK)protocol. hostapd is a daemon for access point and authentication servers used by WPA3 authentication. wpa_supplicant is a wireless supplicant that implements key negotiation with the WPA Authenticator and supports WPA3. Both of these components,as implemented with Extensible Authentication Protocol Password(EAP-PWD)and SAE,are vulnerable as follows: CVE-2019-9494:SAE cache attack against ECC groups(SAE side-channel attacks)- CWE-208 and CWE-524 The implementations of SAE in hostapd and wpa_supplicant are vulnerable to side channel attacks as a result of observable timing differences and cache access patterns. CVE-2019-9495:EAP-PWD cache attack against ECC groups(EAP-PWD side-channel attack)- CWE-524 The implementations of EAP-PWD in hostapd and wpa_supplicant are vulnerable to side channel attacks as a result of cache access patterns. Versions of hostapd and wpa_supplicant versions 2.7 and earlier,with EAP-PWD support are vulnerable. CVE-2019-9496:SAE confirm missing state validation - CWE-642 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. CVE-2019-9497:EAP-PWD reflection attack(EAP-PWD missing commit validation)- CWE-301 The implementations of EAP-PWD in hostapd EAP Server and wpa_supplicant EAP Peer do not validate the scalar and element values in EAP-pwd-Commit. CVE-2019-9498:EAP-PWD server missing commit validation for scalar/element - CWE-346 The implementations of EAP-PWD in hostapd EAP Server,when built against a crypto library missing explicit ..
