SQL injection attacks are increasing at a rapid rate and represent a major threat to web application security.
Scan your web app for critical security vulnerabilities and prevent significant data loss and business disruption.
Use our free SQL injection online scanner to track new security flaws before you get hacked, perform self-assessment to quickly find web app vulnerabilities, and get explicit reports and recommendations to fix them.
The online scanner identifies SQL injection vulnerabilities found in web applications by crawling and performing a deep inspection of web pages and parameters. Find below useful examples in which you can use the SQL Injection scanner powered by OWASP ZAP.
Website Penetration Testing
Speed up your penetration test with our free SQL injection scanner and detect new security flaws in your website. It is easy to install and is configured with the optimal features for best results and effective performance. Just run a scan and wait a few minutes while the results are loading.
As a best practice, you should perform a self-security assessment that allows you to easily detect flaws in your web application. Use this free tool to find and remediate security vulnerabilities before attackers exploit them.
Third-Party Website Audit
The best way to check if your web applications are prone to attacks is by conducting a website security audit. Review your website for potential vulnerabilities and enhance its security posture. If you are a web development company, you can show the report to your customers and demonstrate you've implemented the proper security measures within the web application.
What is an SQL injection and how to prevent this attack?
SQL Injection remains one of the most prevalent attacks used by hackers and a serious security threat to both individuals and companies.
SQLi is also one of the most well-known web application vulnerabilities with a dedicated chapter in the OWASP Top 10 project and is also a highly chased vulnerability in bug bounty programs.
A common SQL injection attack happens when attackers try to insert malicious SQL statements located in an HTTP (or HTTPS) request by changing the current behavior of SQL statements created by the web application.
They do this by first finding a vulnerable user input within a web app and create input content which is often used as the malicious payload to launch this attack. The input provided by an attacker may include characters that could interfere with the SQL syntax and will result in arbitrary SQL queries performed on the database.
As a result, the risk of an SQL Injection vulnerability is that the attacker could:
Read/write information from the database
Read/write files from the disk (in certain conditions)
Execute operating system commands on the database server (in certain conditions)
Here is a sample URL which extracts the type and version of the database server (MySQL) by exploiting the SQL Injection vulnerability:
http://vulnapp.example.com/travel.jsp?id=x' UNION SELECT NULL, NULL, @@version -- '
One of the most common types of SQL injection techniques is error-based SQL injection which is the simplest SQL exploit and easy to detect. It involves using classic HTTP requests by inserting unexpected commands through a user interface to cause the database server to respond with an error that includes information about the target: structure, version, or operating system.
In the below example, an SQL command has been inserted to change the value of the fields Username($username = 1' or '1' = '1) and Password($password = 1' or '1' = '1) which will be modified as follows:
This is an example of a URL with the modified query that will generate an error and let a hacker get access to all the user names and passwords. http://www.example.com/index.php?username=1'%20or%20'1'%20=%20'1'))%20LIMIT%201/*&password=foo
To prevent this from happening, you should avoid using the user input directly in the application code. Developers need to sanitize the input section and remove the potentially malicious code in SQL statements that could allow hackers to gain unauthorized access to sensitive database information: usernames, passwords, and other essential credentials.
Prevention is always the best cure and you can simply detect web application vulnerabilities by using our online scanner.
How does the SQL Scanner work?
To better secure your web applications from SQL injection attack is to identify and fix security vulnerabilities before hackers do.
Our SQL injection scanner was created to easily perform SQL injection testing and find web applications flaws in a timely manner.
The SQL Injection Scanner using OWASP ZAP (Full Scan) is our comprehensive online security solution that allows you to do a complete SQL injection assessment of the target web applications and find critical vulnerabilities with a significant impact for any business.
The online tool offers an intuitive and simple interface using OWASP ZAP , the most popular open-source web application security scanner.
The SQL Injection Scanner (Light Scan) performs a quick and fast scan of a target URL that allows it to identify vulnerabilities in web applications. It does that by searching if the parameters of the target URLs are vulnerable to SQL Injection attack and reports the malicious pages that could affect your website.
The online scanner includes two steps:
Spidering the target: In this first step, the scanner tries to identify all the pages within the target web application, including injectable parameters in login forms, URLs, headers, etc.
Accurate SQL injection testing: During this phase, for each page discovered in the previous step, the online tool will try to detect if the parameters are vulnerable to SQL Injection and report them in the results page.
The table below shows the differences between the Light scan and the Full scan:
Spider max URLs
Spider max duration
Active scan max duration
The SQL Injection tool generates some HTTP requests that can be flagged as attacks on the server side (although they are harmless). We recommend not to perform an SQL injection test if you don't have permission or proper authorization from the owner of the target web app.
Will this tool also check for MySQL Injection?
MySQL is one of the most accessible and widely deployed SQL databases running on websites and systems and also the top target for hackers. They will search for vulnerable user inputs within the MSQL databases, inject malicious code to manipulate them and get unauthorized access.
Our online tool will scan the target URL containing SQL commands and check if the MySQL database has been exposed to any SQL injection vulnerability. It can perform a full SQL injection assessment of the target web application to detect vulnerabilities before being compromised.
Other popular relational database management systems (RDBMS) that are vulnerable to SQL injection are Microsoft SQL Server, Oracle, or SQLite.
This is the URL of the website that will be scanned. All URLs must start with http or https.
This scan is faster but less comprehensive than the full scan.
This is a complete SQL Injection assessment of the target web application.
How it works
Our SQLi Scanner uses the engine from OWASP ZAP, one of the world’s most popular open source security tools, actively maintained by hundreds of international developers and other active community members.
The OWASP ZAP tool was created to help users automatically detect security vulnerabilities in web applications while developing and testing them.
The tool can do an SQL injection test by inserting special characters (eg. ', ", 2*3) in all input fields of the target application and monitoring the web page's behavior. If databases errors are discovered on the website, this could be the scenario of an SQL injection attack.
In order to validate the vulnerability found, the SQL Injection scanner attempts to construct a syntactically correct SQL query that demonstrates the injection was successful. That is why the following results will be displayed: http://vulnapp.example.com/bookings.php?cat=4 AND 1=1 --
The SQL Injection scanner does not attempt to exploit SQL injection, it simply detects the presence of any vulnerability that could affect your backend database.
If flaws are detected, our online tool offers detailed information about the risks you are exposed to and recommendations on how to perform an effective remediation process.
Start scanning for web applications vulnerabilities today so you will not be exposed to SQL injection attack which let hackers get to tamper with sensitive information (such as usernames, passwords, and other essential credentials) by disclosing, or deleting it.
For more in-depth information about SQL Injection attack, including solutions on how to remediate this vulnerability, you can found on the OWASP SQL Injection Page.
