| Título | SourceCodester POS Inventory System 1.0 SQL Injection + Unrestricted File Upload |
|---|
| Descripción | A combined SQL Injection and Unrestricted File Upload vulnerability was discovered in the product management functionality of POS Inventory System Using PHP version 1.0.
SQL Injection: Parameters are directly concatenated into INSERT and UPDATE queries without sanitization:
mysqli_query($conn, "insert into product (product_name, categoryid, product_price, product_qty, photo, supplierid)
values ('$name','$category','$price','$qty','$location','$supplier')");
File Upload: The application only validates the file extension string, which can be bypassed using double extensions or uppercase extensions:
if ($fileInfo['extension'] == "jpg" OR $fileInfo['extension'] == "png") {
$newFilename = $fileInfo['filename'] . "_" . time() . "." . $fileInfo['extension'];
move_uploaded_file($_FILES["image"]["tmp_name"], "../upload/" . $newFilename);
This allows an attacker to upload a PHP webshell and execute arbitrary commands on the server. |
