SQL Injection

Does the cloud Penetrator Find SQL Injection?
Yes it does find SQL Injection and tell you how to fix it. 

It crawls your entire site like a search engine such as Google would do it.

Then it can detect SQL Injection on custom made scripts as well.

Typically it is home written scripts that are vulnerable to SQL Injection.

This can be scripts made by non security personnel at the web agency or local staff.

When the site is vulnerable to SQL Injection it can allow an attacker to inject code in to the target Database and retrieve sensitive information.


What is a SQL Injection?

There are a whole host of different kinds of web attacks that are engineered and used by hackers in order to steal data from organizations.

The sheer number of different kinds of web attacks have increased over the past few years, and as a result of this, there is a significant amount of diversity that has taken place too.

One of the thousands of different kinds of web attacks that are engineered by hackers is a SQL injection.

The primary purpose of a SQL injection is to steal data from organizations, companies or wherever it is targeted.

The SQL injection is by far one of the most popular kinds of application layer techniques that is in use today.

Primarily, the SQL injection tries to capitalize upon the improper coding of you web page.

If the coding of your web page is not done in the right manner, a person with knowledge of hacking will be able to inject SQL commands in to a page, such as a login form, which ultimately allows them to gain access to the database of your website.  

In depth explanation of a SQL injection

The main purpose because of which the SQL injection arises is because the empty fields which are present for user input are able to allow SQL statements to pass through, hence allowing them to send queries to the database without making use of the login form/ authorization process at all.

Web applications primarily allow users to gain access to data, submit and receive it by making use of a very simplistic login system to and from the database.

You can access any website by fulfilling the login form in your web browser of choice and then proceed.

Databases are used for the storage of data that is useful for the suppliers, website users, etc.

Information such as user credentials, financial information, etc. are all easily stored on databases, and can be accessed by those who have proper login verification.

By making use of the SQL injection hacking technique, a person is able to send out SQL commands or statements by using a web application.

These commands are then executed by the backend database. Because of the improper coding that might exist.

Web applications are likely to result in SQL injections which will provide access to hackers who are looking to view the information on a database, or even worse, to wipe it all out.

Common features such as feedback forms, login pages, etc. are all susceptible to SQL injections, provided that they have not been coded properly.

Support pages and product request forms are also susceptible.

A person with sophisticated knowledge of SQL injections is also able to bypass shopping carts and internet based delivery of dynamic content in order to gain access to the back end database and make alterations.

SQL injections have been frequently used in the past by hackers in order to gain access to lower level databases, and as the knowledge of the people have increased, proper security measures are now taken. 

SQL Injection


Structured Query Language/SQL is a programming language.

It is used for managing and organizing data present in a databank/database.

A database is an organized collection of data structures and information and includes critical user details such as login id, password and names, etc.

It can be stated that SQL is a relational database management system.

There are various kinds of management systems that utilize Structured Query Language for instance, Oracle, Microsoft SQL Database, MySQL and PostgreSQL, etc.

What is SQL Injection?

SQL Injection is a type of cyber-attack which hackers employ conveniently for invading a database.

The core idea is to compromise the privacy and security of a database and control the application.

It is a system based upon code injection technique.

Hackers rely upon SQL injection for benefiting from the non-validated input weaknesses for passing SQL commands via a Web application for implementation through a backend databank.

Basically, this system is used for attacking data-driven applications and exploiting security vulnerability or weakness in the application’s software is mandatory.

Why Databases are attacked?

The reasons for attacking can be various and wide-ranged, depending upon the extent of malicious intentions of the hacker.

A database can be hacked for retrieving valuable information from the targeted site and it may involve bypassing the logins and accessing the data.

An example of this sort of attack is the year 2012 Yahoo hack.

Through this kind of attack, hackers can make alterations to the application such as changing or modifying the front page or even the website content.

The highest level of SQL injection attack is shutting down the server of a website.

Why SQL Injections are so common?

The reason is that SQL injection vulnerabilities prevail commonly.

Databases are attractive entities for hackers since these contain personal and confidential information about the users and/or the application.

Moreover, hacking through SQL injection is easy and details about performing this kind of an attack are readily available at diverse forums.

SQL injection represents an opportunistic attack approach for hackers as it doesn’t require extensive knowledge, research or training for conducting this type of hacking.

How an attack is conducted?

Programmers usually chain SQL commands together with parameters provided by users.

This mechanism embeds SQL commands within the parameters, which gives the attackers and edge.

Resultantly, the attackers are able to execute random SQL queries/commands on the backend database server with help of the web application.

SQL injection is a simple procedure:

Scan websites for evaluating if vulnerability exists in a database.

In this regard, Google serves as the perfect tool because by simply employing Google Dork, an attacker can search for weaknesses via Google tricks.

Once the target website is detected and identified, the hacker needs to search for the database containing usernames and directories.

Hacker will search for any structure which contains sensitive data.

How can it be prevented?

According to the SQL Injection Prevention Cheat Sheet provided by the Open Web Application Security Project, there are two types of defense mechanisms: Primary and Additional.

Primary Defenses:

     •   Using parameter queries is important so that developers define the SQL codes and pass them in each parameter to the query.

This allows databases to differentiate between code and data, irrespective of the input.

     •   Stored procedure also helps.

It defines and stores itself in the database and is then accessed from the application instead of allowing users to enter.

     •    Each DBMS backs some sort of character escaping schemes particular to different queries.

If all user input is supplied through proper escaping scheme then the DBMS will not mix-up input with SQL code.

Additional Defenses

     •    By reducing the privileges allotted to a database account.

This will ensure that users enjoy adequate instead of unbounded access.

     •    Input validation can help in detecting illegal input before the application processes it.
