Vulnerabilities in SQL injection | Learn with Fun way Description SQL injection is a type of vulnerability that can allow attackers to inject malicious SQL code into a web application's backend database, potentially giving them access to sensitive data or even taking control of the entire system. What is SQL injection with example? SQL injection usually occurs when you ask a user for input, like their username/userid, and instead of a name/id, the user gives you an SQL statement that you will unknowingly run on your database. Why need to do that course? The course would be structured in a way that is accessible to students with a range of backgrounds and levels of experience. It would start with the basics of SQL injection, including an introduction to SQL and database queries, before moving on to more advanced topics. The course would be designed to be practical and hands-on, with plenty of opportunities for students to gain experience in identifying, testing, and remediating SQL injection vulnerabilities. On that course would cover the following topics: Introduction to SQL injection: Explanation of what SQL injection is, how it works, and the potential impact of an attack. Types of SQL injection: Overview of the different types of SQL injection, including union-based, error-based, blind, and others. Prevention and mitigation techniques: Discussion of the best practices for preventing and mitigating SQL injection vulnerabilities, including parameterized queries, input validation, escaping, and other security measures. Exploitation of SQL injection: Explanation of how attackers can exploit SQL injection vulnerabilities to gain access to sensitive data, install malware, or take control of the system. Detection and testing: Overview of the methods used to detect and test for SQL injection vulnerabilities, including manual testing, automated tools, and other techniques. Case studies and real-world examples: Discussion of real-world examples of SQL injection vulnerabilities, including lessons learned and best practices. Secure coding practices: Overview of the secure coding practices that can help prevent SQL injection vulnerabilities, including input validation, output encoding, and other security measures. Compliance and audits: Explanation of the various regulations, standards, and best practices related to SQL injection and how they are audited and enforced. Patching and remediation: Explanation of how SQL injection vulnerabilities can be patched and remediated, including methods for fixing the underlying code or applying security updates. Hands-on experience: Practical exercises that allow students to gain hands-on experience in identifying, testing, and remediating SQL injection vulnerabilities. Advanced topics: Discussion of more advanced topics related to SQL injection, including bypassing filters, exploiting blind SQL injection, and other advanced techniques. Future trends: Overview of emerging trends and technologies in the field of SQL injection, including machine learning, artificial intelligence, and blockchain. This course would be suitable for developers, security professionals, and anyone interested in improving their understanding of SQL injection vulnerabilities and how to prevent them. By the end of the course, students will be equipped with the knowledge and skills to identify, test for, and remediate SQL injection vulnerabilities in web applications, helping to protect against malicious attacks and safeguard sensitive data.

What is SQL Injection & its Attacks SQL injection is a type of web application vulnerability where an attacker can manipulate and submit a SQL command to retrieve the database information. This type of attack mostly occurs when a web application executes by using the user-provided data without validating or encoding it. It can give access to sensitive information such as social security numbers, credit card numbers, or other financial data to the attacker and allows an attacker to create, read, update, alter, or delete data stored in the backend database. It is a flaw in web applications and not a database or web server issue. Most programmers are still not aware of this threat. Attacks : On the basis of application used and the way it processes user supplied data, SQL injection can be used to implement the attacks mentioned below: Authentication bypass : Here the attacker could enter into the network without providing any authentic user name or password and could gain access over the network. he or she gets the highest privilege in the network. Information disclosure : After the unauthorized entry into the network, the attacjer gets access to sensitive data stored in the database. Compromised data integrity : The attacker changes the main content of the website and also enters malicious content into it. Compromiused availibility of data : The attacker uses this type of attack to delete the data related to audit information or any other crucial database information. Remote code execution : An attacker could modify, delete, or create data or even can create new accounts with full user rights on the server that shares files and folders. It allows an attacker to compromise the host operating system.

It comes with a powerful detection engine, many niche features for the ultimate penetration tester, and a broad range of switches lasting from database fingerprinting, over data fetching from the database to accessing the underlying file system and executing commands on the operating system via out-of-band connections. The sqlmap project is sponsored by Netsparker Web Application Security Scanner. Features implemented in sqlmap include: Full support for MySQL, Oracle, PostgreSQL, Microsoft SQL Server, Microsoft Access, IBM DB2, SQLite, Firebird, Sybase, SAP MaxDB and HSQLDB database management systems. Full support for five SQL injection techniques: boolean-based blind, time-based blind, error-based, UNION query and stacked queries. Support to directly connect to the database without passing via a SQL injection, by providing DBMS credentials, IP address, port and database name. It is possible to provide a single target URL, get the list of targets from Burp proxy or WebScarab proxy requests log files, get the whole HTTP request from a text file or get the list of targets by providing sqlmap with a Google dork which queries Google search engine and parses its results page. You can also define a regular-expression based scope that is used to identify which of the parsed addresses to test. Tests provided GET parameters, POST parameters, HTTP Cookie header values, HTTP User-Agent header value and HTTP Referer header value to identify and exploit SQL injection vulnerabilities. It is also possible to specify a comma-separated list of specific parameter(s) to test. Option to specify the maximum number of concurrent HTTP(S) requests (multi-threading) to speed up the blind SQL injection techniques. Vice versa, it is also possible to specify the number of seconds to hold between each HTTP(S) request. Others optimization switches to speed up the exploitation are implemented too. HTTP Cookie header string support, useful when the web application requires authentication based upon cookies and you have such data or in case you just want to test for and exploit SQL injection on such header values. You can also specify to always URL-encode the Cookie. Automatically handles HTTP Set-Cookie header from the application, re-establishing of the session if it expires. Test and exploit on these values is supported too. Vice versa, you can also force to ignore any Set-Cookie header. HTTP protocol Basic, Digest, NTLM and Certificate authentications support. HTTP(S) proxy support to pass by the requests to the target application that works also with HTTPS requests and with authenticated proxy servers. Options to fake the HTTP Referer header value and the HTTP User-Agent header value specified by user or randomly selected from a textual file. Support to increase the verbosity level of output messages: there exist seven levels of verbosity. Support to parse HTML forms from the target URL and forge HTTP(S) requests against those pages to test the form parameters against vulnerabilities. Granularity and flexibility in terms of both user’s switches and features. Estimated time of arrival support for each query, updated in real time, to provide the user with an overview on how long it will take to retrieve the queries’ output. Automatically saves the session (queries and their output, even if partially retrieved) on a textual file in real time while fetching the data and resumes the injection by parsing the session file. Support to read options from a configuration INI file rather than specify each time all of the switches on the command line. Support also to generate a configuration file based on the command line switches provided. Support to replicate the back-end database tables structure and entries on a local SQLite 3 database. Option to update sqlmap to the latest development version from the subversion repository. Support to parse HTTP(S) responses and display any DBMS error message to the user.

Description SQL injections are a common way to gain unauthorized access to web applications and extract data from them. In this course, instructor Malcolm Shore shows you the SQL command language and how it is used by attackers to craft SQL Injections. Malcolm begins with commonly encountered relational databases and the basics of the SQL command language. Then he focuses on advanced SQL commands that may be used by attackers to achieve SQL injections. Malcolm explains how to use a simple Python script and how an SQL injection changes the backend SQL query. Then he demonstrates how SQL injections could be used to exploit some testing targets. Malcolm steps through the process of automating SQL injection exploits, then finishes with advice on how to continue to hone your skills as a penetration tester.

SQL Blind Injection Tool A script for automatizing boolean-based blind SQL injections. Works with SQLite at least supports using cookies. It uses bitwise comparisons with multithreading to find cell values instead of binary search, which is more efficient. It’s able to: Search cell values by columns in a table Search characters count in a cell by columns in a table Search rows count in a table The search algorithm is shown below. Knowing the name of its column (‘sqlite_master’ by default in sqlite, for example) and the column name of it (‘name’ in sqlite) you can find values of every cell in every row. And the fastest algorithm for this is checking the binary values of every character in every cell, which can be performed using multiple threads. Considering this, we can send only 7 requests to get the standard 7-bit letter, and using 1000 threads, we get ~142 letters per moment (it’s also worth keeping in mind requests to get the length of a cell value).

SQL Injection Tutorial: Learn with Example Data is one of the most vital components of information systems. Database powered web applications are used by the organization to get data from customers. SQL is the acronym for Structured Query Language. It is used to retrieve and manipulate data in the database. What is a SQL Injection? SQL Injection is an attack that poisons dynamic SQL statements to comment out certain parts of the statement or appending a condition that will always be true. It takes advantage of the design flaws in poorly designed web applications to exploit SQL statements to execute malicious SQL code. In this tutorial, you will learn SQL Injection techniques and how you can protect web applications from such attacks. How SQL Injection Works Hacking Activity: SQL Inject a Web Application Other SQL Injection attack types Automation Tools for SQL Injection How to Prevent against SQL Injection Attacks Hacking Activity: Use Havji for SQL Injection How SQL Injection Works The types of attacks that can be performed using SQL injection vary depending on the type of database engine. The attack works on dynamic SQL statements. A dynamic statement is a statement that is generated at run time using parameters password from a web form or URI query string. Let’s consider a simple web application with a login form. The code for the HTML form is shown below. <form action=‘index.php’ method="post"> <input type="email" name="email" required="required"/> <input type="password" name="password"/> <input type="checkbox" name="remember_me" value="Remember me"/> <input type="submit" value="Submit"/> </form> HERE, The above form accepts the email address, and password then submits them to a PHP file named index.php. It has an option of storing the login session in a cookie. We have deduced this from the remember_me checkbox. It uses the post method to submit data. This means the values are not displayed in the URL. Let’s suppose the statement at the backend for checking user ID is as follows SELECT * FROM users WHERE email = $_POST['email'] AND password = md5($_POST['password']); HERE, The above statement uses the values of the $_POST[] array directly without sanitizing them. The password is encrypted using MD5 algorithm. We will illustrate SQL injection attack using sqlfiddle. Open the URL [Hidden Content] in your web browser. You will get the following window. Note: you will have to write the SQL statements Step 1) Enter this code in left pane CREATE TABLE `users` ( `id` INT NOT NULL AUTO_INCREMENT, `email` VARCHAR(45) NULL, `password` VARCHAR(45) NULL, PRIMARY KEY (`id`)); insert into users (email,password) values ('[email protected]',md5('abc')); Step 2) Click Build Schema Step 3) Enter this code in right pane select * from users; Step 4) Click Run SQL. You will see the following result Suppose user supplies [email protected] and 1234 as the password. The statement to be executed against the database would be SELECT * FROM users WHERE email = '[email protected]' AND password = md5('1234'); The above code can be exploited by commenting out the password part and appending a condition that will always be true. Let’s suppose an attacker provides the following input in the email address field. [email protected]' OR 1 = 1 LIMIT 1 -- ' ] xxx for the password. The generated dynamic statement will be as follows. SELECT * FROM users WHERE email = '[email protected]' OR 1 = 1 LIMIT 1 -- ' ] AND password = md5('1234'); HERE, [email protected] ends with a single quote which completes the string quote OR 1 = 1 LIMIT 1 is a condition that will always be true and limits the returned results to only one record. -- ' AND … is a SQL comment that eliminates the password part. Copy the above SQL statement and paste it in SQL FiddleRun SQL Text box as shown below Hacking Activity: SQL Inject a Web Application We have a simple web application at [Hidden Content] that is vulnerable to SQL Injection attacks for demonstration purposes only. The HTML form code above is taken from the login page. The application provides basic security such as sanitizing the email field. This means our above code cannot be used to bypass the login. To get round that, we can instead exploit the password field. The diagram below shows the steps that you must follow Let’s suppose an attacker provides the following input Step 1: Enter [email protected] as the email address Step 2: Enter xxx') OR 1 = 1 -- ] Click on Submit button You will be directed to the dashboard The generated SQL statement will be as follows SELECT * FROM users WHERE email = '[email protected]' AND password = md5('xxx') OR 1 = 1 -- ]'); The diagram below illustrates the statement has been generated. Learn SQL Injection with practical example HERE, The statement intelligently assumes md5 encryption is used Completes the single quote and closing bracket Appends a condition to the statement that will always be true In general, a successful SQL Injection attack attempts a number of different techniques such as the ones demonstrated above to carry out a successful attack. Other SQL Injection attack types SQL Injections can do more harm than just by passing the login algorithms. Some of the attacks include Deleting data Updating data Inserting data Executing commands on the server that can download and install malicious programs such as Trojans Exporting valuable data such as credit card details, email, and passwords to the attacker’s remote server Getting user login details etc The above list is not exhaustive; it just gives you an idea of what SQL Injection Automation Tools for SQL Injection In the above example, we used manual attack techniques based on our vast knowledge of SQL. There are automated tools that can help you perform the attacks more efficiently and within the shortest possible time. These tools include SQLSmack - [Hidden Content] SQLPing 2 - [Hidden Content] SQLMap - [Hidden Content] How to Prevent against SQL Injection Attacks An organization can adopt the following policy to protect itself against SQL Injection attacks. User input should never be trusted - It must always be sanitized before it is used in dynamic SQL statements. Stored procedures – these can encapsulate the SQL statements and treat all input as parameters. Prepared statements –prepared statements to work by creating the SQL statement first then treating all submitted user data as parameters. This has no effect on the syntax of the SQL statement. Regular expressions –these can be used to detect potential harmful code and remove it before executing the SQL statements. Database connection user access rights –only necessary access rights should be given to accounts used to connect to the database. This can help reduce what the SQL statements can perform on the server. Error messages –these should not reveal sensitive information and where exactly an error occurred. Simple custom error messages such as “Sorry, we are experiencing technical errors. The technical team has been contacted. Please try again later” can be used instead of display the SQL statements that caused the error. Hacking Activity: Use Havij for SQL Injection In this practical scenario, we are going to use Havij Advanced SQL Injection program to scan a website for vulnerabilities. Note: your anti-virus program may flag it due to its nature. You should add it to the exclusions list or pause your anti-virus software. The image below shows the main window for Havij Learn SQL Injection with practical example The above tool can be used to assess the vulnerability of a web site/application.
