Someone on my site wrote the following message. He could be just trying to gain access to my site for a hack attempt, but based on what he said, I would like for someone to check all of my php files in my site to see if in fact he is correct. Here is his message:
I have found many holes in the security of your website. Including SQL injection holes, and XSS holes. Your site is thereby vulnerable to session hijacking, and, it also runs the risk of having arbitrary SQL code ran [which could easily take all information from your database, and delete it]. I am a security expert. I am offering my services to you. Respond if you wish to talk about compensation.
Thanks in advance for bidding on this project.
