<p><b>Lesson Plan Title:</b> How to Perform a SQLInjection</p>
|
|
|
|
<p><b>Concept / Topic To Teach:</b><br />
|
|
SQL injection attacks represent a serious threat to any database-driven
|
|
site. The methods behind an attack are easy to learn and the damage
|
|
caused can range from considerable to complete system compromise.
|
|
Despite these risks, an incredible number of systems on the internet are
|
|
susceptible to this form of attack.</p>
|
|
|
|
<p>Not only is it a threat easily instigated, it is also a threat
|
|
that, with a little common-sense and forethought, can easily be
|
|
prevented.</p>
|
|
|
|
<p>It is always good practice to sanitize all input data, especially
|
|
data that will used in OS command, scripts, and database queiries, even
|
|
if the threat of SQL injection has been prevented in some other manner.
|
|
</p>
|
|
|
|
<p><b>General Goal(s):</b><br />
|
|
For this exercise, you will perform SQLInjection attacks. You will also
|
|
implement code changes in the web application to defeat these attacks.</p>
|
|
|
|
<p><b>Solution:</b><br />
|
|
Choose Larry to log in with password larry. Select yourself from the list
|
|
and make sure that WebScarab will intercept the next request. Replace the id 101 with following:
|
|
<br/>
|
|
101 OR 1=1 ORDER BY salary desc <br/>
|
|
<p>With '101 OR 1=1' we have a SQL Statement which is always true. It will
|
|
get all the employees from the db but only return one of them. That is why we have to ensure we get
|
|
the "Big Fish" which is the employee earning most. With 'ORDER BY SALARY DESC' we guarantee exactly this.
