This vulnerability is classified under CWE-346. The implementations of EAP-PWD in hostapd EAP Server, 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 be able to use invalid scalar/element values to complete authentication, gaining session key and network access without needing or learning the password. Both hostapd with SAE support and wpa_supplicant with SAE support prior to and including version 2.4 are affected. Both hostapd with EAP-pwd support and wpa_supplicant with EAP-pwd support prior to and including version 2.7 are affected. Affected products include: W1.Fi Hostapd, W1.Fi Wpa Supplicant, Fedoraproject Fedora, Opensuse Backports Sle, Opensuse Leap. Version information: version 2.4.
