CVE-2023-52160

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.

The wpa_supplicant packages contain an 802.1X Supplicant with support for WEP, WPA, WPA2 (IEEE 802.11i / RSN), and various EAP authentication methods. They implement key negotiation with a WPA Authenticator for client stations and controls the roaming and IEEE 802.11 authentication and association of the WLAN driver.

Security Fix(es):

• wpa_supplicant: potential authorization bypass (CVE-2023-52160)
