CVE-2023-52160

The implementation of PEAP in wpa_supplicant through 2.10 allows authentication bypass.

Impact

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.
