Description

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. 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.
