CWE-287

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.

Affected configurations

• debian debian linux 10.0 • fedoraproject fedora 38 • fedoraproject fedora 39 • redhat enterprise linux 8.0 • redhat enterprise linux 9.0 • w1.fi wpa supplicant (<= 2.10)
