Certified Ethical Hacker (CEH) Practice Question

While testing an e-commerce application you notice that the shopping cart POST request carries a hidden price field that the server uses to calculate the final charge. You change price=1.00 in Burp and still complete the purchase for one dollar. Which application logic flaw has been exploited in this scenario?

  • SQL injection against the products table that overwrites prices

  • Trusting client-supplied price parameters, allowing price tampering

  • Cross-site scripting injected into the checkout form

  • Time-of-check/time-of-use race condition during payment authorization
