Reject a passphrase configuration attempt if that passphrase -includes an invalid passphrase. - -This fixes an issue where wpa_supplicant could have updated the -configuration file psk parameter with arbitrary data from the control -interface or D-Bus interface. While those interfaces are supposed to be -accessible only for trusted users/applications, it may be possible that -an untrusted user has access to a management software component that -does not validate the passphrase value before passing it to -wpa_supplicant. - -This could allow such an untrusted user to inject up to 63 characters of -almost arbitrary data into the configuration file. Such configuration -file could result in wpa_supplicant trying to load a library (e.g., -opensc_engine_path, pkcs11_engine_path, pkcs11_module_path, -load_dynamic_eap) from user controlled location when starting again. -This would allow code from that library to be executed under the -wpa_supplicant process privileges. - -Signed-off-by: Jouni Malinen <jouni@qca.qualcomm.com> ---- - wpa_supplicant/config.c | 6 ++++++ - 1 file changed, 6 insertions(+) - -diff --git a/wpa_supplicant/config.c b/wpa_supplicant/config.c -index b1c7870..fdd9643 100644 ---- a/wpa_supplicant/config.c -+++ b/wpa_supplicant/config.c -@@ -478,6 +478,12 @@ static int wpa_config_parse_psk(const struct parse_data *data, - } - wpa_hexdump_ascii_key(MSG_MSGDUMP, "PSK (ASCII passphrase)", - (u8 *) value, len); -+ if (has_ctrl_char((u8 *) value, len)) { -+ wpa_printf(MSG_ERROR, -+ "Line %d: Invalid passphrase character", -+ line); -+ return -1; -+ } - if (ssid->passphrase && os_strlen(ssid->passphrase) == len && - os_memcmp(ssid->passphrase, value, len) == 0) { - /* No change to the previously configured value */ --- -1.9.1 - |
