Sql Injection (example) Attack Software Tool Download Content List SQL injectionWe'll define SQL injection, provide several instances, explain how to detect and attack different types of SQL injection vulnerabilities, and conclude how to avoid SQL injection in this part. What is SQL injection (SQLi) and how does it work? SQL injection is a kind of online security flaw that enables an attacker to tamper with a web application's database queries. It enables an attacker to see data that they wouldn't ordinarily be able to see. This might include data belonging to other users or any other information that the app has access to. In many circumstances, an attacker may edit or remove this data, causing the application's content or behavior to be permanently altered. An attacker may use a SQL injection attack to compromise the underlying server or other back-end infrastructure, or to launch a denial-of-service attack in certain cases. What kind of damage may a successful SQL injection attack cause? Unauthorized access to sensitive data, such as passwords, credit card numbers, or personal user information, might arise from a successful SQL injection attack. SQL injection attacks have been the cause of several high-profile data breaches in recent years, resulting in reputational harm and regulatory penalties. An attacker may sometimes get a persistent backdoor into a company's systems, resulting in a long-term penetration that goes unreported for a long time. Examples of SQL injection SQL injection vulnerabilities, attacks, and tactics come in a range of shapes and sizes, and they may be used in a variety of ways. The following are some instances of SQL injection: You may change a SQL query to obtain more results when retrieving concealed data. You may alter a query to interfere with the program's logic, which is known as subverting application logic. You may use UNION attacks to get data from many database tables. Examining the database, which allows you to extract information about the database's version and structure. The results of a query you control are not returned in the application's answers, which is known as blind SQL injection. Retrieving data that has been concealed Consider a shopping app that shows items from several categories. When a user selects the Gifts category, their browser sends a request to the following URL:https://site.com/products?category=GiftsThis prompts the program to issue a SQL query to the database in order to gather information about the relevant products:SELECT * FROM products WHERE category = 'Gifts' AND released = 1This SQL query asks the database to return:all details (*)from the products tablewhere the category is Giftsand released is 1.The restriction released = 1 is being used to hide products that are not released. For unreleased products, presumably released = 0.The application doesn't implement any defenses against SQL injection attacks, so an attacker can construct an attack like:https://site.com/products?category=Gifts'--This results in the SQL query:SELECT * FROM products WHERE category = 'Gifts'--' AND released = 1The key thing here is that the double-dash sequence -- is a comment indicator in SQL, and means that the rest of the query is interpreted as a comment. This effectively removes the remainder of the query, so it no longer includes AND released = 1. This means that all products are displayed, including unreleased products.Going further, an attacker can cause the application to display all the products in any category, including categories that they don't know about:https://website.com/products?category=Gifts'+OR+1=1--This results in the SQL query:SELECT * FROM products WHERE category = 'Gifts' OR 1=1--' AND released = 1The modified query will return all items where either the category is Gifts, or 1 is equal to 1. Since 1=1 is always true, the query will return all items.Subverting the logic of the application Consider a program that requires a login and password to access. When a user enters the username wiener and the password bluecheese, the program does the following SQL query to verify the credentials:SELECT * FROM users WHERE username = 'wiener' AND password = 'bluecheese'If the query returns the details of a user, then the login is successful. Otherwise, it is rejected.Here, an attacker can log in as any user without a password simply by using the SQL comment sequence -- to remove the password check from the WHERE clause of the query. For example, submitting the username administrator'-- and a blank password results in the following query:SELECT * FROM users WHERE username = 'administrator'--' AND password = ''This query returns the user with the username administrator, and the attacker is successfully logged in as that user.Data from other database tables may be retrieved. An attacker can use a SQL injection vulnerability to retrieve data from other tables within the database if the results of a SQL query are returned within the application's responses. This is accomplished by utilizing the UNION keyword, which allows you to run a second SELECT query and attach the results to the first.For example, if an application executes the following query containing the user input "Gifts":SELECT name, description FROM products WHERE category = 'Gifts'then an attacker can submit the input:' UNION SELECT username, password FROM users--The program will then return all users and passwords, as well as product names and descriptions.Investigating the database Following the first detection of a SQL injection vulnerability, it's usually a good idea to learn more about the database. This data is often used to prepare the path for subsequent exploitation. The database's version information may be queried. Because the method for doing so is dependent on the database type, you may deduce the database type from the strategy that works. On Oracle, for example, you may run:SELECT * FROM v$versionYou may also find out what database tables are available and which columns are included in them. For example, to list the tables in most databases, use the following query:SELECT * FROM information_schema.tablesSQL injection flaws with no warning In many cases, SQL injection is a blind vulnerability. This implies that the application's answers do not include the results of the SQL query or information about any database issues. Blind vulnerabilities may still be used to get unwanted access to data, but the procedures are more sophisticated and harder to execute. The following strategies may be used to exploit blind SQL injection vulnerabilities, depending on the nature of the vulnerability and the database involved: You may alter the query logic to cause a discernible variation in the application's answer based on the validity of a single condition. This might include adding a new condition to some Boolean logic or conditionally triggering an error like a divide-by-zero. You may conditionally delay the query's execution, enabling you to deduce the validity of the condition based on how long it takes the application to answer. Using OAST methods, you may initiate an out-of-band network contact. This approach is incredibly effective and may be used in circumstances when other strategies are ineffective. You may often directly exfiltrate data through the out-of-band route, for as by inserting the data into a DNS query for a domain you control.How can SQL Injection Vulnerabilities be Detected? Burp Suite's online vulnerability scanner can rapidly and accurately detect the majority of SQL injection issues. SQL injection may be detected manually by running a series of tests against each application's entry point. This usually entails: Checking for typos or other abnormalities after submitting the single quote character ' Submitting SQL-specific syntax that evaluates to the entry point's base (original) value, as well as a new value, and checking for systematic discrepancies in the application answers.Submitting Boolean conditions such as OR 1=1 and OR 1=2, and looking for differences in the application's responses.Using payloads that are intended to cause time delays when performed inside a SQL query, and checking for discrepancies in response times. Submitting OAST payloads that, when performed inside a SQL query, initiate an out-of-band network interaction, and monitoring for any ensuing interactions.Injection of SQL in various portions of the query The WHERE clause of a SELECT query is where the majority of SQL injection problems occur. Experienced testers are usually familiar with this form of SQL injection. SQL injection vulnerabilities, on the other hand, may occur at any point in the query and across multiple query types. The following are the most prevalent other places when SQL injection occurs:In UPDATE statements, within the updated values or the WHERE clauseIn INSERT statements, within the inserted valuesIn SELECT statements, within the table or column nameIn SELECT statements, within the ORDER BY clauseSQL injection at the second level First-order SQL injection occurs when an application accepts user input from an HTTP request and inadvertently combines it into a SQL query while processing the request. The application takes user input from an HTTP request and stores it for future use in second-order SQL injection (also known as stored SQL injection). This is commonly accomplished by storing the data in a database, but there is no risk at the point of storage. The program then gets the saved data and combines it into a SQL query in an improper manner when processing another HTTP request.Second-order When developers are aware of SQL injection issues, they may securely manage the first insertion of information into the database. Because the data was previously securely stored in the database, it is judged safe when it is processed later. Because the developer incorrectly believes the data to be trustworthy, the data is handled in an unsafe manner at this point. Factors unique to each database Many approaches of identifying and exploiting SQL injection vulnerabilities operate the same way on various kinds of databases because certain key aspects of the SQL language are implemented in the same manner across prominent database systems. There are, however, several variances across typical databases. As a result, several methods for detecting and exploiting SQL injection change depending on the platform. Consider the following scenario:Syntax for string concatenationCommentsBatched (or stacked) queriesPlatform-specific APIsError messages.How can SQL injection be avoided? Instead of string concatenation inside the query, most occurrences of SQL injection may be avoided by utilizing parameterized queries (also known as prepared statements). Because the user input is concatenated straight into the query, the following code is susceptible to SQL injection:String query = "SELECT * FROM products WHERE category = '"+ input + "'";Statement statement = connection.createStatement();ResultSet resultSet = statement.executeQuery(query);This code can be easily rewritten in a way that prevents the user input from interfering with the query structure:PreparedStatement statement = connection.prepareStatement("SELECT * FROM products WHERE category = ?");Parameterized queries may be utilized in any case where untrusted input is used as data, such as the WHERE clause and values in an INSERT or UPDATE command. They can't be used to deal with untrustworthy input in other portions of the query, such table or column names, or the ORDER BY clause. Application functionality that inserts untrusted data into specific areas of the query will need to take an alternative approach, such as white-listing acceptable input values or using other logic to get the desired result. In order for a parameterized query to be successful in avoiding SQL injection, the query string must always be a hard-coded constant and must never include any variable data from any source. Don't be tempted to judge whether a piece of data is trustworthy on a case-by-case basis; instead, for circumstances that are regarded safe, continue to use string concatenation inside the query. It's all too simple to make assumptions about the provenance of data or to have modifications in other programs contradict assumptions about what data is contaminated.The Best SQL Injection Tools are listed below. SQL injection is one of the most prevalent online application threats. A SQL injection attack involves inserting or "injecting" a SQL query into the program through the client's input data. A successful SQL injection exploit can read sensitive data from the database, modify database data (Insert/Update/Delete), perform database administration operations (such as shutting down the DBMS), recover the content of a given file on the DBMS file system, and, in some cases, issue commands to the operating system. Passwords, emails, usernames, and other sensitive server data may be accessed if a SQL injection attack is successful. SQL injection may be quite dangerous. The following is a list of the greatest and most widely used SQL injection programs: SQLMap - Automatic SQL Injection And Database Takeover TooljSQL Injection - Java Tool For Automatic SQL Database InjectionBBQSQL - A Blind SQL Injection Exploitation ToolNoSQLMap - Automated NoSQL Database PwnageWhitewidow - SQL Vulnerability ScannerDSSS - Damn Small SQLi Scannerexplo - Human And Machine Readable Web Vulnerability Testing FormatBlind-Sql-Bitshifting - Blind SQL Injection via BitshiftingLeviathan - Wide Range Mass Audit ToolkitBlisqy - Exploit Time-based blind-SQL injection in HTTP-Headers (MySQL/MariaDB)I'm not going to go into the specifics of these seminars. In the past, we've covered a number of SQL injection lessons. You may use the search option to look through our resources. Because developers are unconcerned about data validation and security, SQL injection vulnerabilities exist. Users' input must be sanitized before being sent into SQL queries, yet many developers fail to do so or do it incorrectly. As a result, the web application is susceptible to SQL injection. By injecting queries in multiple parameters, a browser-based attack may easily do conventional SQL injection. It does, however, need a working grasp of SQL queries. You must be an expert with extensive understanding of database queries, database design, and experience to do blind SQL injection or any other kind of SQL injection. And manual methods take a long time. SQL injection tools have been created by providing a good detection engine to make the SQL injection attack procedure easier. These tools are growing smarter with each new version. The vulnerable URL is sent as a parameter to these tools, which subsequently attack the victim. These tools can recognize the sort of assault thanks to their detection and attack engine. A vulnerable URL may be protected by a session and need authentication. As a result, these tools now have the ability to connect to a web site using a username and password given by the user in order to conduct SQL injection in the target application. These tools can easily do GET-based, POST-based, and cookie-based SQL injection. These tools can carry out an assault automatically, and you will get a successful attack outcome in a matter of minutes. These technologies also enable you to access any database table or column with a single click and attack procedure. You may use commands to access data in CLI tools. You may also use these tools to conduct SQL queries in the target database. As a result, you have access to the target server's data and may alter or delete it. Attackers may also use these tools to upload and download files from the server. We've included a couple open source SQL injection tools in this article. These tools are quite strong, and they can carry out automated SQL injection attacks on the target apps. I'll also provide a download link so you can test out the tool. I did my best to compile a list of the greatest and most widely used SQL injection tools. Hacker for BSQL BSQL Hacker is a useful SQL injection tool for performing SQL injection attacks on online sites. This solution is for individuals who need a SQL injection tool that works automatically. It's designed specifically for blind SQL injection. This program is quick and uses a multi-threaded approach to provide better and quicker results. It may be used to defend against four main types of SQL injection attacks: SQL Injection in the Dark Blindness based on time Injection of SQL data Deep Sighted (based on advanced time delays) SQL Injection with Errors SQL Injection with Errors This program operates in an automated mode and can retrieve the majority of data from a database. It supports both the GUI and the console. You may experiment with any of the available UI modes. You may also store or load saved attack data from GUI mode. Multiple injection points are supported, including the query string, HTTP headers, POST, and cookies. It allows for the use of a proxy to carry out the assault. It can also get into web accounts using the default authentication information and carry out the attack from that account. It works with SSL-protected URLs as well as SSL URLs with expired certificates. MSSQL, ORACLE, and MySQL are all supported by the BSQL Hacker SQL injection tool. However, MySQL support is experimental on this database server and is not as effective as it is on the other two. SQLmap Among all SQL injection tools available, SQLMap is the most popular open source SQL injection tool. This program makes it simple to attack a web application's SQL injection vulnerability and take control of the database server. It has a robust detection engine that can quickly identify the majority of SQL injection issues. MySQL, Oracle, PostgreSQL, Microsoft SQL Server, Microsoft Access, IBM DB2, SQLite, Firebird, Sybase, SAP MaxDB, and HSQLDB are among the database servers it supports. The majority of commonly used database servers are already included. SQL injection attacks such as boolean-based blind, time-based blind, error-based, UNION query-based, stacked queries, and out-of-band are also supported. The application contains a built-in password hash recognition algorithm, which is a nice feature. It aids in the identification of the password hash and the subsequent cracking of the password using a dictionary attack. When the database server is MySQL, PostgreSQL, or Microsoft SQL Server, this program enables you to download or upload any file from the database server. It also enables you to run arbitrary commands and obtain their normal output on the database server, but only for these three database servers. After connecting to a database server, this tool allows you to search the whole database server for a certain database name, specific tables, or specified columns. When you need to search for a certain field but the database server is too large and includes too many databases and tables, this is a really handy option. Download SQL Map from the following link: https://github.com/sqlmapproject/sqlmap SQLninja SQLninja is a SQL injection tool that targets online sites that utilize a SQL server to store data. At initially, this tool may not be able to locate the injection site. If it is detected, however, it is simple to automate the exploitation process and retrieve data from the database server. This program may deactivate data execution prevention by adding remote shots to the database server OS's registry. The tool's ultimate goal is to provide the attacker remote access to a SQL database server. It may also be used in conjunction with Metasploit to provide graphical access to a remote database. It also supports TCP and UDP bindshells, both direct and reverse. This program is not compatible with Windows. It is currently only available for Linux, FreeBSD, Mac OS X, and iOS. Download SQLninja from the following link: http://sqlninja.sourceforge.net/ SQL injector Safe3 Another strong yet simple to use SQL injection tool is Safe3 SQL Injector. It, like other SQL injection tools, automates the SQL injection process and aids attackers in exploiting the SQL injection vulnerability to obtain access to a remote SQL server. It features a strong AI engine that can quickly identify the database server, injection type, and the best strategy to exploit the flaw. It can handle both HTTP and HTTPS sites. SQL injection may be done through GET, POST, or cookies. To conduct a SQL injection attack, it also supports authentication (Basic, Digest, and NTLM HTTP authentications). MySQL, Oracle, PostgreSQL, Microsoft SQL Server, Microsoft Access, SQLite, Firebird, Sybase, and SAP MaxDB database management systems are all supported by the program. It also enables read, list, and write any file from the database server for MYSQL and MS SQL. It also allows attackers to run arbitrary instructions and receive the results on an Oracle or Microsoft SQL server database server. It also includes features such as web path guessing, MD5 cracking, domain querying, and a thorough SQL injection scan. From the following website, you may get the Safe3 SQL injector tool: http://sourceforge.net/projects/safe3si/ SQLSusSQLSus is a MySQL injection and takeover tool that is another open source SQL injection tool. This utility is developed in Perl, and you may add your own code to enhance the functionalities. This program has a command line interface that allows you to insert SQL queries and conduct SQL injection attacks. This program promises to be quick and effective. It promises to increase the amount of data acquired by using a sophisticated blind injection attack technique. It also employs stacked subqueries for improved results. It has multi-threading to perform attacks in multiple threads, which speeds up the process even more. It also supports HTTPS, much as other SQL injection tools. It may attack using both GET and POST methods. Cookies, socks proxy, HTTP authentication, and binary data retrieval are also supported. If access to information schema is denied or the table does not exist, a bruteforce approach may be used to determine the table's name. You may also use this tool to clone a database, table, or column into a local SQLite database and use it in several sessions. If you wish to use a SQL injection tool to defend against a MySQL attack, this is the program to use since it is tailored to this particular database server. SQLsus may be downloaded from the following link: http://sqlsus.sourceforge.net/ Mole Mole, often known as (The Mole), is a free automated SQL injection tool.
