SQLMap<\/strong><\/a> is a free tool that checks on database vulnerabilities<\/b>. If you run a website, you\u2019re vulnerable to a range of SQL-based hacker attacks that can compromise the database that lies behind many site functions. If hackers can break into your network and infect an endpoint, they can also use SQL injection techniques to compromise those databases that support back-office functions<\/b>.<\/p>\n

Your database lies at the heart of your business information system. It drives data sharing in ERP systems and stores sensitive data<\/b>, such as customer records and turnover information. To fully understand potential vulnerability in this area, you need to know what an SQL injection attack is.<\/p>\n

What is an SQL Injection Attack?<\/h2>\n

SQL Injection (SQLi) is a type of cyberattack where malicious actors exploit vulnerabilities in an application’s database query process. By injecting specially crafted SQL statements into input fields (such as login forms or search bars), attackers can manipulate the database and execute unauthorized actions. These actions might include retrieving, modifying, or even deleting sensitive data.<\/p>\n

How SQL Injection Works<\/h2>\n

SQL injection occurs when user input is directly incorporated into SQL queries without proper validation or sanitization. For example, consider a login form that uses the following query to authenticate users:<\/p>\n

<\/p>\n

SELECT * FROM users WHERE username = ‘user_input’ AND password = ‘user_input’;<\/p>\n

If the application doesn’t sanitize input, an attacker could enter user_input like this:
\n‘ OR ‘1’=’1<\/p>\n

The resulting query becomes:
\nSELECT * FROM users WHERE username = ” OR ‘1’=’1′ AND password = ” OR ‘1’=’1′;<\/p>\n

<\/div>\n

This query always evaluates to true, allowing unauthorized access.<\/p>\n

Consequences of SQL Injection<\/h2>\n

SQL injection can have severe consequences, such as:<\/p>\n
