The implementation of PEAP in wpa_supplicant allowed 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.



For Debian 8 jessie, these problems have been fixed in version 2.3-1+deb8u14.

For Debian 9 stretch, these problems have been fixed in version 2:2.4-1+deb9u10.

We recommend that you upgrade your wpa packages.
