Various PEAP -specifications are not exactly clear on what the behavior on this front -is supposed to be and as such, this ended up being more flexible than -the TTLS/FAST/TEAP cases. However, this is not really ideal when -unfortunately common misconfiguration of PEAP is used in deployed -devices where the server trust root (ca_cert) is not configured or the -user has an easy option for allowing this validation step to be skipped. - -Change the default PEAP client behavior to be to require Phase 2 -authentication to be successfully completed for cases where TLS session -resumption is not used and the client certificate has not been -configured. Those two exceptions are the main cases where a deployed -authentication server might skip Phase 2 and as such, where a more -strict default behavior could result in undesired interoperability -issues. Requiring Phase 2 authentication will end up disabling TLS -session resumption automatically to avoid interoperability issues. - -Allow Phase 2 authentication behavior to be configured with a new phase1 -configuration parameter option: -'phase2_auth' option can be used to control Phase 2 (i.e., within TLS -tunnel) behavior for PEAP: - * 0 = do not require Phase 2 authentication - * 1 = require Phase 2 authentication when client certificate - (private_key/client_cert) is no used and TLS session resumption was - not used (default) - * 2 = require Phase 2 authentication in all cases - -Signed-off-by: Jouni Malinen <j@w1.fi> ---- - src/eap_peer/eap_config.h | 8 ++++++++ - src/eap_peer/eap_peap.c | 40 +++++++++++++++++++++++++++++++++++--- - src/eap_peer/eap_tls_common.c | 6 ++++++ - src/eap_peer/eap_tls_common.h | 5 +++++ - wpa_supplicant/wpa_supplicant.conf | 7 +++++++ - 5 files changed, 63 insertions(+), 3 deletions(-) - -diff --git a/src/eap_peer/eap_config.h b/src/eap_peer/eap_config.h -index 26744ab68..58d5a1359 100644 ---- a/src/eap_peer/eap_config.h -+++ b/src/eap_peer/eap_config.h -@@ -471,6 +471,14 @@ struct eap_peer_config { - * 1 = use cryptobinding if server supports it - * 2 = require cryptobinding - * -+ * phase2_auth option can be used to control Phase 2 (i.e., within TLS -+ * tunnel) behavior for PEAP: -+ * 0 = do not require Phase 2 authentication -+ * 1 = require Phase 2 authentication when client certificate -+ * (private_key/client_cert) is no used and TLS session resumption was -+ * not used (default) -+ * 2 = require Phase 2 authentication in all cases -+ * - * EAP-WSC (WPS) uses following options: pin=Device_Password and - * uuid=Device_UUID - * -diff --git a/src/eap_peer/eap_peap.c b/src/eap_peer/eap_peap.c -index 12e30df29..608069719 100644 ---- a/src/eap_peer/eap_peap.c -+++ b/src/eap_peer/eap_peap.c -@@ -67,6 +67,7 @@ struct eap_peap_data { - u8 cmk[20]; - int soh; /* Whether IF-TNCCS-SOH (Statement of Health; Microsoft NAP) - * is enabled. */ -+ enum { NO_AUTH, FOR_INITIAL, ALWAYS } phase2_auth; - }; - - -@@ -114,6 +115,19 @@ static void eap_peap_parse_phase1(struct eap_peap_data *data, - wpa_printf(MSG_DEBUG, "EAP-PEAP: Require cryptobinding"); - } - -+ if (os_strstr(phase1, "phase2_auth=0")) { -+ data->phase2_auth = NO_AUTH; -+ wpa_printf(MSG_DEBUG, -+ "EAP-PEAP: Do not require Phase 2 authentication"); -+ } else if (os_strstr(phase1, "phase2_auth=1")) { -+ data->phase2_auth = FOR_INITIAL; -+ wpa_printf(MSG_DEBUG, -+ "EAP-PEAP: Require Phase 2 authentication for initial connection"); -+ } else if (os_strstr(phase1, "phase2_auth=2")) { -+ data->phase2_auth = ALWAYS; -+ wpa_printf(MSG_DEBUG, -+ "EAP-PEAP: Require Phase 2 authentication for all cases"); -+ } - #ifdef EAP_TNC - if (os_strstr(phase1, "tnc=soh2")) { - data->soh = 2; -@@ -142,6 +156,7 @@ static void * eap_peap_init(struct eap_sm *sm) - data->force_peap_version = -1; - data->peap_outer_success = 2; - data->crypto_binding = OPTIONAL_BINDING; -+ data->phase2_auth = FOR_INITIAL; - - if (config && config->phase1) - eap_peap_parse_phase1(data, config->phase1); -@@ -454,6 +469,20 @@ static int eap_tlv_validate_cryptobinding(struct eap_sm *sm, - } - - -+static bool peap_phase2_sufficient(struct eap_sm *sm, -+ struct eap_peap_data *data) -+{ -+ if ((data->phase2_auth == ALWAYS || -+ (data->phase2_auth == FOR_INITIAL && -+ !tls_connection_resumed(sm->ssl_ctx, data->ssl.conn) && -+ !data->ssl.client_cert_conf) || -+ data->phase2_eap_started) && -+ !data->phase2_eap_success) -+ return false; -+ return true; -+} -+ -+ - /** - * eap_tlv_process - Process a received EAP-TLV message and generate a response - * @sm: Pointer to EAP state machine allocated with eap_peer_sm_init() -@@ -568,6 +597,11 @@ static int eap_tlv_process(struct eap_sm *sm, struct eap_peap_data *data, - " - force failed Phase 2"); - resp_status = EAP_TLV_RESULT_FAILURE; - ret->decision = DECISION_FAIL; -+ } else if (!peap_phase2_sufficient(sm, data)) { -+ wpa_printf(MSG_INFO, -+ "EAP-PEAP: Server indicated Phase 2 success, but sufficient Phase 2 authentication has not been completed"); -+ resp_status = EAP_TLV_RESULT_FAILURE; -+ ret->decision = DECISION_FAIL; - } else { - resp_status = EAP_TLV_RESULT_SUCCESS; - ret->decision = DECISION_UNCOND_SUCC; -@@ -887,8 +921,7 @@ continue_req: - /* EAP-Success within TLS tunnel is used to indicate - * shutdown of the TLS channel.
