The will let us write a backdoor to the system that we can use. The good part about mysql from a hacker-perspective is that you can actaully use slq to write files to the system. If it lods for four seconds exta we know that the database is processing our sleep() command. To know if it is correct or not we can however use the sleep statement. Since we do not have access to the logs we do not know if our commands are syntaxically correct or not. But it is of course still possible to exploit. This make the whole process a lot more complicated. We say that it is blind because we do not have access to the error log.

The 0x3a only servers to create a delimitor between name and password union select 1,2,3,4,column_name,6,7,8,9 from information_lumns where table_name = 'users' union select 1,2,3,4,table_name,6,7,8,9 from information_schema.tables
Some of the syntaxes may difference depending on the database engine (mysql, mssql, postgres). Here is a list of data we can retrieve from the database. For example if columns number five has been visible in step 3, we can use that to output the data. Now we can use that field to start outputing data. This will return the numbers of the columns that are being outputted on the website. So we do the command like this union select 1,2,3,4,5,6,7,8,9įor all the columns that exists. To find out which columns are being outputted we can use the union select command. It could be that not all data from the database is worthwhile to output, so maybe only column 1 and 3 are being outputted to the website. Now we need to know which coolumns are being outputed on the webpage. So you just increase the number (or do a binary tree search if you want tot do it a bit faster) until you get an error, and you know how many columns the table has. And we will know how many columns the table has. Because if we do order by 10 when there really only is 9 columns sql will throw an error. But we can use it to find out how many columns a table has. So it is basically just a tool to order the data in a table. Order by 2 means sort by values of the second column from the result set. Order by 1 means sort by values of the first column from the result set. So in order to enumerate the columns of a table we can use the order by If the page then returns a blank page or a page with a sql-error we know that the page it vulnerable. So first we should try to break the sql-syntaxt by adding a '. If we manage to find an error-message after a broken sql-query, we can use that to try to map out the database structure.įor example, if we have a url that end with The two main ways for perform a sql-injection: error based or blind.

So let's learn sql-injections the manual way. And also it is good to understand the vulnerability in the cote and not just run tools. Sqlmap is good, but it is not very stealthy. This is the most classic, standard first test: ' or '1'='1 Proxy credencials -proxy-cred="username:password" sqlmap -r request.txt -p username -dbms=mysql -dump -D Webapp -T Users 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.
