Descriptions

The implementation of PEAP in wpa_supplicant through 2.10 allows authentication bypass. For a successful attack, wpa_supplicant must be configured to not verify the network's TLS certificate during Phase 1 authentication, and an eap_peap_decrypt vulnerability can then be abused to skip Phase 2 authentication. The attack vector is sending an EAP-TLV Success packet instead of starting Phase 2. This allows an adversary to impersonate Enterprise Wi-Fi networks.

La implementación de PEAP en wpa_supplicant hasta la versión 2.10 permite omitir la autenticación. Para un ataque exitoso, se debe configurar wpa_supplicant para no verificar el certificado TLS de la red durante la autenticación de la Fase 1, y luego se puede abusar de una vulnerabilidad eap_peap_decrypt para omitir la autenticación de la Fase 2. El vector de ataque envía un paquete de éxito EAP-TLV en lugar de iniciar la Fase 2. Esto permite a un adversario hacerse pasar por redes Wi-Fi empresariales.

A flaw was found in wpa_supplicant's implementation of PEAP. This issue may allow an attacker to skip the second phase of authentication when the target device has not been properly configured to verify the authentication server. By skipping the second phase of authentication, it’s easier for an attacker to create a rogue clone of a trusted WiFi network to trick the victim into connecting, all without knowing their password.
