PHP MYSQL INSERT SQL INJECTION CODE
Now, PHP and MySQL code to test the attack on security. Search for magic_quotes_gpc = On in php.ini, and change it to magic_quotes_gpc = Off. Now, your database and table is ready to test SQL injection attack, you need to check, if your magic_quotes_gpc is enabled or not! Check with this code: var_dump(get_magic_quotes_gpc()) If the output is true(1) then you need to disable it first to see SQL Injection in action! Insert Sample data to the table: INSERT INTO `user` (`id`, `user`, `password`) VALUES ) ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=3 `id` smallint(5) unsigned NOT NULL AUTO_INCREMENT, Here is code to setup table on your local database: CREATE TABLE IF NOT EXISTS `user` (
I have complete set of code to see SQL Injection in Action. In this case, seeing the SQL injection in action is not possible and it is not good for learner who want to see it to believe it. Big problem with those sql injection examples are that when you try to see yourself SQL Injection in action, you may find it difficult to reproduce it. One example explanation can be found here at PHP site itself. SQL Injection attack is very common security vulnerability and it is document at many places. For the attack, attacker need to know a little about your database schema but getting those small details is not difficult, Many times developers output the mysql error or because they did not bothered to catch the error PHP just outputted the error to screen. So, whatever security was available due to magic quotes will go after PHP version 5.3. Note that 0 is to supply a valid offset to the original query and to terminate it. If it happened, then the script would present a superuser access to him. Earlier PHP has magic_quotes_gpc() On by default but now after version 5.3 it will be deprecated. 0 insert into pgshadow (usename,usesysid,usesuper,usecatupd,passwd) select 'crack', usesysid, 't','t','crack' from pgshadow where usename'postgres'.
SQL injection is one very common attack on PHP application.
