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> + +CVE: CVE-2023-52160 +Upstream-Status: Backport [https://w1.fi/cgit/hostap/commit/?id=8e6485a1bcb0baffdea9e55255a81270b768439c] + +Signed-off-by: Claus Stovgaard <claus.stovgaard@gmail.com> + +--- + 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 3238f74..047eec2 100644 +--- a/src/eap_peer/eap_config.h ++++ b/src/eap_peer/eap_config.h +@@ -469,6 +469,14 @@ 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 12e30df..6080697 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.
