SimplCommerce is affected by a race condition vulnerability in the checkout logic, allowing multiple users to purchase more products than are in stock via simultaneous checkout requests.
An attacker can detect this vulnerability by attempting to purchase a product at almost the same time with limited stock (stock = 1) using two accounts. If both accounts successfully purchase the product, it confirms the presence of a race condition. This can be done using custom scripts or Burp Suite turbo intruder to send concurrent checkout requests.
