, an attack program can run on any SQL statement or stored procedure. By using xp_mongoshell to expand the stored procedure, an attack program can also run under the operating system command. Obviously, this is a serious vulnerability. Protect your own database. Do you know how to prevent SQL injection

execution result is true, you can smoothly enter the background. For a digital injection attack, you must use intval () to forcibly convert the parameter to a number before any numeric parameter is put into the database, so as to cut off the generation of the Digital Injection Vulnerability. For example: $ id = intval ($ _ GET ['id']); Select * from articles where id = '$ id '; Enter: id = 5' or 1 = 1% 23

If the user enters a Web page and inserts it into the MySQL database, there is an opportunity to leave the security issue known as SQL injection open. This lesson will teach you how to help prevent this from happening and help protect scripts and MySQL statements. Injection typically occurs when processing a user inpu
