| 제목 | SourceCodester POS Inventory System 1.0 SQL Injection (Error-Based / UNION-Based) |
|---|
| 설명 | A SQL Injection vulnerability via unsanitized GET parameter was discovered in the delete functionality of POS Inventory System Using PHP version 1.0.
The application retrieves the id value directly from $_GET['id'] and concatenates it into SQL queries without sanitization, type casting, or the use of prepared statements. This occurs in multiple files
deleteproduct.php:
$pid = $_GET['id'];
$a = mysqli_query($conn, "select * from product where productid='$pid'");
mysqli_query($conn, "delete from product where productid='$pid'");
deletecustomer.php:
$id = $_GET['id'];
mysqli_query($conn, "delete from user where userid='$id'");
mysqli_query($conn, "delete from customer where userid='$id'");
The vulnerability allows any authenticated user to delete arbitrary records from the database or exfiltrate sensitive data via UNION-based injection. |
