So, what happened? We can deduct that the string was interpreted by the SQL command processor and executed it different than it supposed to. If it were, it wouldn’t have returned any results.

This means that, behind de scenes, the database wasn’t in fact queried by that string ( 2016′ order by 1 - ‘ ). As we can see in the picture above, it did return one result, even though the input contains a lot of weird characters. So, we’re going to try to “ search” for the following string: 2016′ order by 1 - ‘. Exploit the application The first thing we want to try is in fact if the application is susceptible to SQL injections or not.

Therefore, nothing “hacky” is implemented in the back-end nor the front-end, except that poor constructed SQL query.Ģ. The only thing to note here is that we have a table with 3 columns and we display the cars coming from the back-end.
#Advanced sql injection tool manual
The piece of code which will actually permit us to try out some injections is the manual concatenation of the String year in the query (“select * from cars where year = ‘” + year + “‘” ) Below is how we filter out the cars from the database using a wrongimplementation for constructing a SQL select.Ībove, we are getting from the database all the cars which match the year a user enters in the UI. jsp page displayed (the “welcome” page) along with a model ( the filtered cars) which we will display in the UI. We have the view which will be the actual. For those of you who have used Spring before, this is just a classic Controller which calls out a DAO which retrieves all the cars by a year (the service layer is missing since it’s out of the scope of this article). Let’s have a look behind the scenes and see how this page is being implemented/rendered in terms of back-end / front-end. This type of functionality is present in most of the web applications – a page for displaying customer information data and some field(s) to do additional filtering on the data. We can also search the cars table by year. Hetzner South Africa hacked – Sensitive information exposed 4 In 2017, a web hosting company’s platform was hacked, exposing customer details, FTP passwords, domain names, and banking details.Here’s how Bell was hacked – SQL injection blow-by-blow 3 The data breach consisted of almost 40,000 usernames and passwords. Back in 2014, Canadian telecom company, Bell, was hacked and tens of thousands of customers’ records were leaked online.In recent years, there has been media coverage on attacks on data-driven applications, as these types of attacks are still being used to hack big companies and retrieve sensitive information. SQL injection must exploit a security vulnerability in an application’s software, for example, when user input is either incorrectly filtered for string literal escape characters embedded in SQL statements or user input is not strongly typed and unexpectedly executed.” 2 to dump the database contents to the attacker). The attacker’s input data can trick the interpreter into executing unintended commands or accessing data without proper authorization.Īccording to Wikipedia, “ SQL injection is a code injection technique, used to attack data-driven applications, in which nefarious SQL statements are inserted into an entry field for execution (e.g. 1 The flaw occurs when untrusted data is sent to back-end to be used, more often, as a searched term inside a query, but, due to a poor application development, it ends up being interpreted as part of a command or query. According to OWASP top 10 application security risks dating from 2017, injection flaws (such as SQL, NoSQL, LDAP) still occupies the first place.
