Descriptions

The implementations of EAP-PWD in wpa_supplicant 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 with a client. 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.

Las implementaciones del componente EAP-PWD en wpa_supplicant EAP Peer, cuando se construyen contra una biblioteca criptográfica que carece de comprobación explícita en elementos importados, no comprueban los valores escalares y de elementos en EAP-pwd-Commit. Un atacante puede completar la identificación, la clave de sesión y el control de la conexión de datos con un cliente. Tanto hostapd con soporte SAE como wpa_supplicant con soporte SAE anterior e incluyendo la versión 2.4 son impactados. Tanto hostapd con soporte EAP-pwd como wpa_supplicant con soporte EAP-pwd anterior y con la versión 2.7 están impactados.
