Simple 2 part project....
Ideally I would love to have both aspects covered, but feel free to bid on either of the parts if you're unable to do both.
Have 2-3 basic php web forms that are used for collecting billing info and posting payment data to authorize.net.
(Simple meaning: name, address, credit card info, etc.)
Forms were written several years ago and are quite insecure and I'm pretty sure that someone has been able to exploit them to upload shell script files.
Part 1: Need these forms updated or re-written to function as they do now but to be secure
Part 2: Fully explain and demonstrate to me how these forms are being exploited.
I would love to have a good understanding of how this is happening so that I can check for other similar forms that may need to be addressed and so I can prevent it from happening again.
I make no "upfront" payments of any kind.
I pay in full upon successful completion of project.
Feel free to see my feedback, as if this isn't acceptable, please don't bid.
