|---|
| Description | The affected components are the root `locateus.php` and `ulocateus.php` doctor search endpoints. The `doctorname` POST value is concatenated directly into the LIKE pattern:
```php
$doctor=$_POST['doctorname'];
$sql1 = "Select * from Doctor where UPPER(name) like UPPER('%".$doctor."%')";
$result1=mysqli_query($conn, $sql1);
```
Because the value sits inside `UPPER('%...%')`, an attacker can inject `x%') OR SLEEP(2) -- -` to break out of the function call and execute arbitrary SQL. This is unauthenticated and enables blind/time-based SQL injection. |
