SQL Injection (SQLi) refers to an injection attack wherein an attacker can execute malicious SQL statements (also commonly referred to as a malicious payload) that control a web application’s database server (also commonly referred to as a Relational Database Management System – RDBMS). Since an SQL Injection vulnerability could possibly affect any website or web application that makes use of an SQL-based database, the vulnerability is one of the oldest, most prevalent and most dangerous of web application vulnerabilities. By leveraging an SQL Injection vulnerability, given the right circumstances, an attacker can use it to bypass a web application’s authentication and authorization mechanisms and retrieve the contents of an entire database. SQL Injection can also be used to add, modify and delete records in a database, affecting data integrity. To such an extent, SQL Injection can provide an attacker with unauthorized access to sensitive data including, customer data, personally identifiable information (PII), trade secrets, intellectual property and other sensitive information. How SQL Injection works In order to run malicious SQL queries against a database server, an attacker must first find an input within the web application that is included inside of an SQL query. In order for an SQL Injection attack to take place, the vulnerable website needs to directly include user input within an SQL statement.

An attacker can then insert a payload that will be included as part of the SQL query and run against the database server. The following server-side pseudo-code is used to authenticate users to the web application. # Define POST variables uname = request.POST['username'] passwd = request.POST['password'] # SQL query vulnerable to SQLi sql = “SELECT id FROM users WHERE username=’” + uname + “’ AND password=’” + passwd + “’” # Execute the SQL statement database.execute(sql) The above script is a simple example of authenticating a user with a username and a password against a database with a table named users, and a username and password column.

The above script is vulnerable to SQL Injection because an attacker could submit malicious input in such a way that would alter the SQL statement being executed by the database server. A simple example of an SQL Injection payload could be something as simple as setting the password field to password’ OR 1=1. This would result in the following SQL query being run against the database server. SELECT id FROM users WHERE username=’username’ AND password=’password’ OR 1=1’ An attacker can also comment out the rest of the SQL statement to control the execution of the SQL query further. -- MySQL, MSSQL, Oracle, PostgreSQL, SQLite ' OR '1'='1' -- ' OR '1'='1' /* -- MySQL ' OR '1'='1' # -- Access (using null characters) ' OR '1'='1'%00 ' OR '1'='1'%16 Once the query executes, the result is returned to the application to be processed, resulting in an authentication bypass. In the event of authentication bypass being possible, the application will most likely log the attacker in with the first account from the query result — the first account in a database is usually of an administrative user.

What’s the worst an attacker can do with SQL? SQL is a programming language designed for managing data stored in an RDBMS, therefore SQL can be used to access, modify and delete data. Furthermore, in specific cases, an RDBMS could also run commands on the operating system from an SQL statement.

Keeping the above in mind, when considering the following, it’s easier to understand how lucrative a successful SQL Injection attack can be for an attacker. • An attacker can use SQL Injection to bypass authentication or even impersonate specific users. • One of SQL’s primary functions is to select data based on a query and output the result of that query. An SQL Injection vulnerability could allow the complete disclosure of data residing on a database server. • Since web applications use SQL to alter data within a database, an attacker could use SQL Injection to alter data stored in a database. Altering data affects data integrity and could cause repudiation issues, for instance, issues such as voiding transactions, altering balances and other records.

• SQL is used to delete records from a database. An attacker could use an SQL Injection vulnerability to delete data from a database. Even if an appropriate backup strategy is employed, deletion of data could affect an application’s availability until the database is restored. • Some database servers are configured (intentional or otherwise) to allow arbitrary execution of operating system commands on the database server. Given the right conditions, an attacker could use SQL Injection as the initial vector in an attack of an internal network that sits behind a firewall.

The anatomy of an SQL Injection attack An SQL Injection needs just two conditions to exist – a relational database that uses SQL, and a user controllable input which is directly used in an SQL query. In the example below, it shall be assumed that the attacker’s goal is to exfiltrate data from a database by exploiting an SQL Injection vulnerability present in a web application.

Supplying an SQL statement with improper input, for example providing a string when the SQL query is expecting an integer, or purposely inserting a syntax error in an SQL statement cause the database server to throw an error. Errors are very useful to developers during development, but if enabled on a live site, they can reveal a lot of information to an attacker. SQL errors tend to be descriptive to the point where it is possible for an attacker to obtain information about the structure of the database, and in some cases, even to enumerate an entire database just through extracting information from error messages – this technique is referred to as error-based SQL Injection. To such an extent, database errors should be disabled on a live site, or logged to a file with restricted access instead. Another common technique for exfiltrating data is to leverage the UNION SQL operator, allowing an attacker to combine the results of two or more SELECT statements into a single result. This forces the application to return data within the HTTP response – this technique is referred to as union-based SQL Injection.

The following is an example of such a technique. This can be seen on testphp.vulnweb.com, an intentionally vulnerable website hosted by Acunetix. The following HTTP request is a normal request that a legitimate user would send. GET HTTP/1.1 Host: testphp.vulnweb.com Although the above request looks normal, the artist parameter in the GET request’s query string is vulnerable to SQL Injection.

The SQL Injection payload below modifies the query to look for an inexistent record by setting the value in the URL’s query string to -1 (it could be any other value that does not exist in the database, however, an ID in a database is less likely to be a negative number). In SQL Injection, the UNION operator is commonly used to allow an attacker to join a malicious SQL query to the original query intended to be run by the web application. The result of the injected query will be joined to the result of the original query, allowing an attacker to exfiltrate data out of a database by obtaining values of columns from other tables. GET UNION SELECT 1, 2, 3 HTTP/1.1 Host: testphp.vulnweb.com The above example proves that the query to the database can be modified to return data which an attacker may want to extract.

The following example shows how an SQL Injection payload could be used to exfiltrate data from this intentionally vulnerable site. GET UNION SELECT 1,pass,cc FROM users WHERE uname='test' HTTP/1.1 Host: testphp.vulnweb.com Further reading.

Advanced SQL injection Hello everybody, since i started learning SQLi, i have collected lots of good tools,tutorials and documents, m still collecting more and more day by day as my scope of knowledge is increasing. So thought of sharing what i have collected till now with everyone here, My tool pack includes the following things. 1) sqli scanner/automating injection pack: contains 5 softwares for scanning,and automating the hacking process (a) Exploit scanner - for finding websites with dorks, and testing them for vulnerabilities.very famous (b) Turkish ARTA - same as exploit scanner but not as famous bcos its turkish. I find it better then exploit scanner.

But that my personal opinion (a) Havij 1.12 free version: i guess everyone knows about it. It automates the process of performing sqli attack on any site.

It is extremely famous and efficient. Poni Hoax Sigrid Rar Files. But still it a tool:) nothing compared to manual process (b) SQLI helper 2.7: same like havij, but little fast.

(e)sqlinj Version 2 - another nice sql injection tool. I will write a tut later how to use this tool 2) ADMIN Finder pack: After getting the logins from the database. One needs to get the admin finder page. For some sites its very easy while for smoe site its hellova tough here are some nice admin finder tools and lists tht u may use. But these tools are never enough.i will keep uploaing the amin finder lists as i get more (a)reiiuke admin finder ( u can upadt the original admin finder lists with the list i am providing) (b)5 perl and python admin finder tools/scripts. Update them as per ur need (c) misc softwre: admin pass locater, to brute force admi pass if u cant find it YOU MIGHT ALSO LIKE THIS SITE 3) DORKS Pack: Contains many files contiaing more then 7000 dorks.

4) Shells: this pack contins many shells and source codes, like c99,c100, jackel and hellova more ( many shells like c99 are identified as trojans by many antivirus. So u might find ur antivirus shouting about this pack. ) U might also wanna see this site: 5) MD5 cracking tools: although havij have md5 tool but for some reason it never worked for me. So this pack contains some tools. ASLO THESE SITES WILL PROVE YOU GREAT HELP 6) SQLI tutorials pack: This pack contain complete html pages of sqli tutorails that i found useful from various forums and websites like hackforum, elitesoft,warex, outlaws etc etc.

I bet every newbe will love this pack. U just need a firefox browser to open these html files. NOTE: this pack also contain 2 of my own created sqli help files which i created myself, serves me as a very useful docment wheneever i m on to hack some site. I will kep updating these packs as i learn and collect more and more.

NOTE: Virus information All files are in winrar format so if u dont want to extract due to virus suspicion then dont extract that particular file 1) the sqli helper 2.7 is identified as some trojan.even if u download the tool formt th original site u will get that virus alert. So i guess its false postive.(onw extract if u dont want. I dont care 2)SHELL pack will definately alert you for virus, bcos it contains many shell that are considered as trojna, extract it or not, choice is urs.again i dont care 3)ADMIN FINDER pack: some antivirus treat them as hack tools. So might get alreat. False positives. TIP: before start learning sqli injection.
