Product | Affected Versions

MinimogWP WordPress Theme | All versions up to and including 3.9.0

How the Exploit Works

The vulnerability stems from the failure of the MinimogWP WordPress theme to adequately check quantity values when they are changed in the cart. This failure allows an unauthenticated attacker to modify the quantity of items in the cart to a fractional amount, which subsequently changes the total price based on the fractional amount.

Conceptual Example Code

Below is a conceptual example of how the vulnerability might be exploited:

POST /cart/update HTTP/1.1
Host: target.example.com
Content-Type: application/json
{
"item_id": "123",
"quantity": "0.1"
}

In this example, the attacker sends a POST request to the /cart/update endpoint, changing the quantity of the item with id “123” to “0.1”. This changes the total price to 10% of the original price.

Mitigation Guidance

Vendors are advised to apply the available patch immediately. Temporary mitigation can be achieved by using a Web Application Firewall (WAF) or Intrusion Detection System (IDS). It is also recommended to upgrade WooCommerce to version 9.8.2 or above, as the vulnerability cannot be exploited with this version installed.
