Official description

The Order Tip for WooCommerce plugin for WordPress is vulnerable to Unauthenticated Improper Input Validation in all versions up to, and including, 1.5.4. This is due to lack of server-side validation on the `data-tip` attribute, which makes it possible for unauthenticated attackers to apply an excessive or even negative tip amount, resulting in unauthorized discount up to free orders depending on the value submitted.

The underlying weakness: Client-Side Enforcement of Server-Side Security

The product includes a server that relies on the client to implement a protection mechanism that is intended to protect the server.

How developers prevent this class of flaw

  • If some degree of trust is required between the two entities, then use integrity checking and strong authentication to ensure that the inputs are coming from a trusted source. Design the product so that this trust is managed in a centralized fashion, especially if there are complex or numerous communication channels, in order to reduce the risks that the implementer will mistakenly omit a check in a single code path.
