Here we are dumping the database Webapp and the table Users. Crawl a page to find sql-injections sqlmap -u -crawl=1 Since the cookie is saved in the reuqest sqlmap can do it. You just cature the request using burp suite, and save the requiest in a file. So you need to authenticate before you can access the vulnerable paramter. Sqlmap is a great tool to perform sql-injections. $query = "SELECT * FROM users WHERE username = 'admin' AND password='whatever' OR '1'='1'" If you know the username you could of course use that and then only inject on the password parameter. Since they both become true the database will retrieve all users and we will be able to bypass the login.
The query will look like this: $query = "SELECT * FROM users WHERE username = 'whatever' OR '1'='1' AND password='whatever' OR '1'='1'" So if we input the following into the user-field and password-field in the login: whatever' or '1'='1 So just like in xss-injections we just try to escape the input field to be able to execute sql-commands. Which means that what the users puts in in the login-form will be executed my mysql. So the user input is not filtered or sanitized in any way. $query = "SELECT * FROM users WHERE username = '$username' AND password='$password'" We have a login functionality, where the code looks like this: mysql_connect( "localhost", "pelle", "mySecretPassowrd") or die(mysql_error()) So we have a website that is written in php.
