But what exactly is Havij, what is SQL injection, and how can you use Havij on Mac OS? In this article, we will answer these questions and more. We will also provide you with some alternatives to Havij in case you want to try other tools for SQL injection testing.




Havij For Mac Os



What is Havij?




Havij is an automated SQL injection tool that helps penetration testers to find and exploit SQL injection vulnerabilities on a web page. It's a completely automated SQL injection tool and it is dispersed by ITSecTeam, an Iranian security organization. The name Havij signifies \"carrot\", which is the apparatus' symbol.


Havij has a simple and user-friendly graphical user interface that makes it easy for anyone to use it. It has many features that make it a powerful tool for SQL injection testing, such as:


  • Support for various types of SQL injection techniques, such as error-based, union-based, blind-based, time-based, etc.



  • Ability to retrieve database information, such as version, name, tables, columns, rows, etc.



  • Ability to dump data from the database, such as usernames, passwords, email addresses, credit card numbers, etc.



  • Ability to execute commands on the server, such as creating files, uploading files, downloading files, etc.



  • Ability to bypass web application firewalls and other security measures.



Havij was first released in 2009 and has since become one of the most popular tools for SQL injection testing among penetration testers and hackers. It has been used in many high-profile cyberattacks, such as the attack on Sony Pictures in 2011, the attack on the Indian government website in 2013, and the attack on the Pakistan government website in 2014.


What is SQL injection?




SQL injection examples




SQL injection is a type of web application vulnerability that allows an attacker to inject malicious SQL statements into a web page's input fields, such as a login form, a search box, or a comment section. These SQL statements are then executed by the web server's database, which can result in unauthorized access, data leakage, data manipulation, data destruction, or even complete takeover of the server.


For example, suppose you have a login form on your website that asks for a username and a password. The login form sends the user input to the server, which then queries the database to check if the username and password are valid. The query might look something like this:


SELECT * FROM users WHERE username = '$username' AND password = '$password'


Now, suppose an attacker enters the following input into the username field:


' OR 1 = 1 --


The query will then become:


SELECT * FROM users WHERE username = '' OR 1 = 1 --' AND password = '$password'


The double dash (--) is a comment symbol in SQL, which means everything after it will be ignored by the database. The OR 1 = 1 condition is always true, which means the query will return all the records from the users table. The attacker will then be able to log in as any user without knowing their password.


SQL injection impacts




A successful SQL injection attack can have serious impacts on the web application and its users. Depending on the type and level of access that the attacker gains, they can perform various malicious actions, such as:


  • Data theft: The attacker can extract sensitive data from the database, such as personal information, financial information, confidential documents, etc.



  • Data manipulation: The attacker can modify or delete data from the database, such as changing prices, updating records, dropping tables, etc.



  • Data destruction: The attacker can erase all the data from the database, rendering it unusable and causing data loss.



  • Backdoor access: The attacker can create a backdoor on the server that allows them to access it remotely and execute commands.



  • Denial-of-service: The attacker can overload the server with excessive requests or commands that consume its resources and cause it to crash or slow down.



These impacts can result in financial losses, reputation damage, legal liabilities, or even physical harm for the web application owner and its users.


SQL injection prevention




The best way to prevent SQL injection attacks is to follow secure coding practices and implement proper input validation and sanitization on both the client-side and the server-side. Some of the common methods to prevent SQL injection attacks are:


  • Input validation: This involves checking the user input for any illegal or unexpected characters or values that could be used for SQL injection. For example, you can use regular expressions or whitelists to filter out any non-alphanumeric characters or keywords from the user input.



  • Parameterization: This involves using parameterized queries or prepared statements that separate the user input from the SQL query structure. For example, you can use placeholders or bind variables that are replaced with the user input at runtime. This way, the user input is treated as a literal value rather than part of the SQL query.



  • Escaping: This involves adding escape characters (\) before any special characters or keywords that could be used for SQL injection. For example, you can use addslashes() function in PHP or mysql_real_escape_string() function in MySQL to escape any single quotes (') or double quotes (") in the user input.



  • Encoding: This involves converting the user input into a different format that is not interpreted by the SQL engine. For example, you can use HTML entities or URL encoding to encode any special characters or keywords in the user input.



Besides these methods, you Besides these methods, you can also use other security measures to protect your web application from SQL injection attacks, such as:


  • Web application firewall: This is a software or hardware device that monitors and filters the incoming and outgoing web traffic and blocks any malicious requests or responses that could be used for SQL injection.



  • Database permissions: This involves limiting the access and privileges of the database user that is used by the web application. For example, you can grant only the minimum necessary permissions for the database user, such as read-only or write-only, and restrict them from executing any commands or accessing any sensitive data.



  • Database encryption: This involves encrypting the data stored in the database using a secret key or a password. This way, even if the attacker manages to dump the data from the database, they will not be able to read or use it without knowing the key or the password.

Configuring Havij settings




Before you start using Havij for SQL injection testing, you need to configure some settings that will affect how Havij works and interacts with the target web page. Here are some of the settings that you need to configure:



SettingDescription


TargetThis is where you enter the URL of the target web page that you want to test for SQL injection. You can also enter a list of URLs if you want to scan multiple web pages at once.


MethodThis is where you choose the HTTP method that Havij will use to send requests to the target web page. You can choose between GET or POST methods. GET method sends the user input as part of the URL, while POST method sends it as part of the body of the request.


ProxyThis is where you enter the proxy server details if you want to use a proxy server to hide your identity or bypass any restrictions on the target web page. You can enter the proxy server address, port, username, and password.


User AgentThis is where you enter the user agent string that Havij will use to identify itself to the target web server. You can choose from a list of predefined user agents or enter your own custom user agent.


CookieThis is where you enter the cookie value that Havij will use to authenticate itself to the target web server. You can copy and paste the cookie value from your browser or enter your own custom cookie value.


To configure these settings, you need to click on the Settings button on the top right corner of Havij's main window. Then, you need to fill in the required fields and click on Save.


Performing SQL injection with Havij




After configuring Havij's settings, you are ready to perform SQL injection with Havij. Here are the steps to perform SQL injection with Havij:


  • Enter the target URL in the Target field and click on Analyze. Havij will scan the target web page and try to find any vulnerable parameters that can be used for SQL injection.



  • If Havij finds any vulnerable parameters, it will display them in the Tables section. You can select the parameter that you want to test and click on Get DBs. Havij will try to retrieve the database name from the target web server.



  • If Havij successfully retrieves the database name, it will display it in the Database section. You can select the database that you want to test and click on Get Tables. Havij will try to retrieve the table names from the target database.



  • If Havij successfully retrieves the table names, it will display them in the Tables section. You can select the table that you want to test and click on Get Columns. Havij will try to retrieve the column names from the target table.



  • If Havij successfully retrieves the column names, it will display them in the Columns section. You can select the columns that you want to test and click on Get Data. Havij will try to dump the data from the target columns.



  • If Havij successfully dumps the data, it will display it in the Data section. You can view, save, or export the data as you wish.



  • If you want to execute commands on the target web server, you can use the CMD tab. You can enter any command that you want to execute and click on Execute. Havij will try to run the command on the target web server and display the output.



By following these steps, you can perform SQL injection with Havij and exploit any SQL injection vulnerabilities that you find on a web page.


What are the alternatives to Havij?

To use Sqlmap on Mac OS, you need to install Python 2.7 or 3.x and download Sqlmap from https://github.com/sqlmapproject/sqlmap. Then, you need to open a terminal window and navigate to the Sqlmap folder. To run Sqlmap, you need to use the following syntax:


python sqlmap.py [options]


The options are various parameters that you can use to customize your SQL injection testing with Sqlmap. Some of the options are:


  • -u or --url: This is where you enter the target URL that you want to test for SQL injection. You can also enter a list of URLs or a file containing URLs.



  • -p or --param: This is where you specify the parameter that you want to test for SQL injection. You can also use an asterisk (*) to test all the parameters.



  • -d or --data: This is where you enter the data that you want to send via POST method. You can also use an asterisk (*) to test all the data.



  • --cookie: This is where you enter the cookie value that you want to use for authentication.



  • --user-agent: This is where you enter the user agent string that you want to use for identification.



  • --proxy: This is where you enter the proxy server details that you want to use for anonymity.



  • --dbms: This is where you specify the database management system that you want to test. You can choose from a list of supported databases or let Sqlmap detect it automatically.



  • --technique: This is where you specify the SQL injection technique that you want to use. You can choose from a list of supported techniques or let Sqlmap choose it automatically.



  • --level: This is where you specify the level of tests that you want to perform. The higher the level, the more tests Sqlmap will perform, but also the more time and requests it will take.



  • --risk: This is where you specify the risk of tests that you want to perform. The higher the risk, the more intrusive and potentially harmful tests Sqlmap will perform, but also the more likely it will find SQL injection vulnerabilities.



For example, if you want to test the target URL https://example.com/login.php with the username parameter using GET method and error-based SQL injection technique, you can use the following command:


python sqlmap.py -u "https://example.com/login.php?username=*" --technique=E


Sqlmap will then scan the target URL and try to find and exploit any SQL injection vulnerabilities using error-based technique. It will display the results on the terminal window and also save them in a log file in the Sqlmap folder.


Microsoft Office Access




Microsoft Office Access is a desktop database application that allows you to create and manipulate data sources. You can use Access to import, export, query, analyze, and report data from various sources, such as Excel, SQL Server, Oracle, etc. You can also use Access to create forms, macros, modules, and reports that enhance your data management and presentation.


To use Access for SQL injection testing, you need to have Microsoft Office installed on your Mac OS. You can download Microsoft Office from https://www.microsoft.com/en-us/microsoft-365/mac/microsoft-365-for-mac. Then, you need to open Access and create a new blank database or open an existing database. To perform SQL injection testing with Access, you need to follow these steps:


  • Create a new table or open an existing table that contains the data that you want to test for SQL injection. You can also import or link data from other sources, such as Excel, SQL Server, Oracle, etc.



  • Create a new query or open an existing query that contains the SQL statement that you want to test for SQL injection. You can also use the Query Wizard or Design View to create or modify your query.



  • Enter the user input that you want to test for SQL injection in the Criteria row of the query. You can use any SQL injection technique or payload that suits your purpose.



  • Run the query and see the results. If the query returns unexpected results or errors, it means that there is a SQL injection vulnerability in your SQL statement or data source.



For example, suppose you have a table called Users that contains usernames and passwords of your web application users. You also have a query called Login that checks if a username and password are valid. The query looks something like this:


SELECT * FROM Users WHERE Username = [Enter Username] AND Password = [Enter Password]


Now, suppose you enter the following input in the Criteria row of the query: Username: ' OR 1 = 1 -- Password: anything


The query will then become:


SELECT * FROM Users WHERE Username = '' OR 1 = 1 --' AND Password = 'anything'


The double dash (--) is a comment symbol in SQL, which means everything after it will be ignored by the database. The OR 1 = 1 condition is always true, which means the query will return all the records from the Users table. This means that there is a SQL injection vulnerability in your query or data source.


LibreOffice Base




LibreOffice Base is a free and open source database application that allows you to create and manipulate data sources. You can use Base to import, export, query, analyze, and report data from various sources, such as MySQL, PostgreSQL, Oracle, etc. You can also use Base to create forms, macros, modules, and reports that enhance your data management and presentation.
