SQL injection attacks exploit vulnerabilities in applications that improperly handle user input, allowing attackers to manipulate database queries. This can lead to unauthorized data access, modification, or deletion.

Scenario: A WordPress site allows users to submit comments containing arbitrary text. An attacker could craft a malicious comment including a carefully crafted SQL statement within the comment input field.

Attacker’s Action: The comment is submitted to the database, but instead of just storing the comment, the attacker’s malicious input is executed as a database query. This could be something like:

SELECT

FROM users WHERE username = ‘admin’ OR ‘1’=’1′;

This SQL query effectively bypasses the username check and returns all user information. The attacker now has access to sensitive data.

Real-World Example: Numerous applications, including those from major software companies, have been affected by SQL injection flaws in the past. The impact can range from leaking customer data to granting attackers administrative privileges.

Prevention: Always sanitize and validate user input before using it in database queries. Parameterized queries are a crucial defense mechanism. This method prevents the attacker’s input from being interpreted as part of the SQL query itself.

Example Prevention Code

Vulnerable Code (Illustrative):

“`php$username = $_POST[‘username’];$query = “SELECT

FROM users WHERE username = ‘$username'”;

“`

Secure Code (Illustrative):

“`php$username = $_POST[‘username’];$query = $wpdb->prepare(“SELECT

FROM users WHERE username = %s”, $username);

“`

Using $wpdb->prepare() (a WordPress function) ensures that the input is treated as data, not code, preventing malicious SQL from being executed.
