Multiple SQL injection vulnerabilities in Zen Cart 1.3.0.2 and earlier allow remote attackers to execute arbitrary SQL commands via (1) GPC data to the ipngetstoredsession function in ipnmainhandler.php, which can be leveraged to modify elements of $SESSION; and allow remote authenticated users to execute arbitrary SQL commands via (2) a session id within a cookie to whosonlinesessionrecreate, (3) the quantity field to the addcart function, (4) an id[] parameter when adding an item to a shopping cart, or (5) a redemption code when checking out (dcredeemcode parameter to includes/modules/ordertotal/otcoupon.php).
