|---|
| Descrição | The affected components are the root AJAX endpoints `get_town.php`, `getclinic.php`, `getdoctordaybooking.php`, and `getDay.php`. Each one concatenates a POST parameter into a SQL query without escaping:
```php
// get_town.php
$query = "SELECT * FROM clinic WHERE City = '" . $_POST["countryid"] . "'";
// getclinic.php
$query = "SELECT * FROM clinic WHERE Town = '" . $_POST["townid"] . "'";
// getdoctordaybooking.php
$query = "SELECT distinct DID FROM doctor_availability WHERE CID =".$_POST["cid"];
// getDay.php
$query = "SELECT * FROM doctor_availability WHERE DID = '" . $_POST["didval"] . "' AND CID='".$_POST["cidval"]."'";
```
These endpoints require no authentication. An attacker can inject `SLEEP()` expressions and observe measurable response delays (e.g. `time_total=2.004s`, `10.016s`), confirming blind SQL injection and enabling time-based data exfiltration.
