I got a webshop with paypal api that auto gives a virtual curency, lets call it coins1 (equal to the value send by paypal)
That can also be converted to another virtual curency through website. (coins2)
Somehow in one of these functions there is a way to exploit it, the coins1 value becomes negative and they get lots of coins2.
Am not sure if its an sql inject or other type of exploit, and im kinda betting on the convert function having a problem since they get huge amounts of coins2 while coins1 goes negative.
I have experience with this type of work. Your site will be safe in no time. Let me check it out and tell you exactly how long it will take and how easy it is to be fixed.
