The implementation of PEAP in wpa_supplicant through 2.10 allows authentication bypass.
MEDIUM 6.5EPSS 1.18%
Does this matter?
Lower severity and a low EPSS score (1.18%). Track it; it rarely justifies an emergency change on its own.
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.
