Summary
[none]
Details

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 wpasupplicant with SAE support prior to and including version 2.4 are affected. Both hostapd with EAP-pwd support and wpasupplicant with EAP-pwd support prior to and including version 2.7 are affected.
