Title
Bagisto has IDOR in Customer Order Reorder Functionality
Summary
Bagisto is an open source laravel eCommerce platform. Prior to version 2.3.10, 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. Version 2.3.10 patches the issue.

Mitigation
Architecture and Design

For each and every data access, ensure that the user has sufficient privilege to access the record that is being requested.

Mitigation
Architecture and Design Implementation

Make sure that the key that is used in the lookup of a specific user's record is not controllable externally by the user or that any tampering can be detected.

Mitigation
Architecture and Design

Use encryption in order to make it more difficult to guess other legitimate values of the key or associate a digital signature with the key so that the server can verify that there has been no tampering.
