UNION SELECT is used to combine results from multiple SELECT statements into a single result. Now that we know how many columns the current table has, we will use UNION to see which column is vulnerable. If we use a higher number, we donвЂ™t get any results: +ORDER+BY+11Дepending on the setup, we might get an error: In our case, we have identified 10 columns: +ORDER+BY+10 However, if the number is larger than the total number of columns, we will get an error because there is no such column.

If the number that we pass in the parameter is less than the total number of columns in the current table, the output of the application should not change because the SQL query is valid. In this case, we need to use the number of the column. You can order either by column name or by the number of the column. ORDER BY is used to set the order of the results. We will use column ordering to achieve that.

We need to find table names to be able to grab the administratorвЂ™s password later.ДЇirst, we need to find out how many columns the current table has. LetвЂ™s assume that we donвЂ™t know the structure of the database or that the administrator used non-default naming/prefixes when installing WordPress. We want to get access to the administration area of the website.

We have identified the SQL injection vulnerability, now letвЂ™s proceed with the attack. If we can control the query, we can control the results. If our input is being parsed as part of the query, we can control it using SQL commands. The MySQL error that we get confirms that the application is indeed vulnerable:ДЄt this point, it is almost certain that soon we will be able to exfiltrate data from the backend database of the web application. One of the most common and simple ones is the use of a single quote which under certain circumstances breaks the database query: вЂ™ There are many ways to identify whether an application is vulnerable to SQL injection. Ideally, we want to see an SQL error which could indicate that our input is parsed as part of a query. What we are looking for is to see if our input causes the output of the application to change in any way. The first thing someone would do is to manipulate the entry point (user input: $_GET parameter) and observe the response. The endpoint is directly accessible, which could indicate weak security. During our penetration test, we have identified a plugin endpoint that accepts the user ID via a $_GET request and displays their user name. Just for reference, the following scenario is executed on a Linux machine running Ubuntu 16.04.1 LTS, PHP 7.0, MySQL 5.7, and WordPress 4.9.ДЇor the purposes of this demonstration, we have performed a security audit on a sample web application. LetвЂ™s see step-by-step how dangerous the exploitation of an SQL Injection can be.

That means that the user is controlling the query string and can adjust it accordingly to with SQL code to manipulate the results. If a user changes the parameter to 1 AND 1=2, it returns nothing because 1 is not equal to 2. There is an article with an id of 1, and 1 equals to 1 which is true. In this case, the content of the page does not change because the two conditions in the SQL statement are both true. If a user sets the value of the article parameter to 1 AND 1=1, the query becomes: $query = 'SELECT * FROM articles WHERE articleid = 1 AND 1=1' $query = 'SELECT * FROM articles WHERE articleid = $articleid' ДЄ typical page in this web application would look as follows: The $articleid parameter is passed as part of the query The underlying PHP source code is the following: // The article parameter is assigned to $article variable without any sanitization or validation LetвЂ™s suppose that we have a web application that takes the parameter article via a $_GET request and queries the SQL database to get article content. Example of Vulnerable CodeД«efore having a practical look at this injection technique, letвЂ™s first quickly see what is SQL Injection. In this article, we see how and why SQLi attacks have such a big impact on application security. If a userвЂ™s input is being passed unvalidated and unsanitized as part of an SQL query, the user can manipulate the query itself and force it to return different data than what it was supposed to return. SQL Injection is one of the most dangerous vulnerabilities a web application can be prone to. We will start off with a basic SQL Injection attack directed at a web application and leading to privilege escalation to OS root. In this series, we will be showing step-by-step examples of common attacks.
