Below is an example of a vulnerable click.php script

along with a description of how the vulnerability occurs and why it is problematic:

---

Sample Vulnerable click.php Script

<?php
// Connect to the database
$conn = new mysqli('localhost', 'username', 'password', 'database');

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

// Retrieve the ID parameter from the URL
$id = $_GET['id'];

// Construct the SQL query
$query = "SELECT * FROM clicks WHERE id = '$id'";

// Execute the query
$result = $conn->query($query);

// Display the result
if ($result->num_rows > 0) {
    while ($row = $result->fetch_assoc()) {
        echo "ID: " . $row['id'] . " - Clicks: " . $row['click_count'] . "<br>";
    }
} else {
    echo "No records found.";
}

$conn->close();
?>

---

Description of Vulnerability

1. Vulnerability: This script is vulnerable to SQL Injection. It directly includes the id parameter from the URL ($_GET['id']) into the SQL query without any validation or sanitization. An attacker could manipulate this parameter to inject malicious SQL code.
2. How It Can Be Exploited:
   • If an attacker sends a URL like click.php?id=1' OR '1'='1, the resulting SQL query becomes: SELECT * FROM clicks WHERE id = '1' OR '1'='1' This query will return all rows in the clicks table, bypassing the intended logic.
   • Worse, an attacker could execute destructive commands, such as deleting data, if the database user has sufficient privileges.
3. Impact:
   • Data breach: Unauthorized access to sensitive data.
   • Data manipulation: Inserting, updating, or deleting records maliciously.
   • Potential server compromise: Combined with other vulnerabilities, attackers could gain deeper access.

---

Mitigation

To secure the script, use prepared statements with parameterized queries:

<?php
// Connect to the database
$conn = new mysqli('localhost', 'username', 'password', 'database');

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

// Retrieve the ID parameter from the URL
$id = $_GET['id'];

// Use a prepared statement to prevent SQL Injection
$stmt = $conn->prepare("SELECT * FROM clicks WHERE id = ?");
$stmt->bind_param("i", $id);

// Execute the statement
$stmt->execute();
$result = $stmt->get_result();

// Display the result
if ($result->num_rows > 0) {
    while ($row = $result->fetch_assoc()) {
        echo "ID: " . $row['id'] . " - Clicks: " . $row['click_count'] . "<br>";
    }
} else {
    echo "No records found.";
}

$stmt->close();
$conn->close();
?>

Explanation of Fix:

• Prepared Statements: The ? placeholder ensures that user input is treated as data, not executable SQL.
• Parameter Binding: bind_param() binds user input securely, preventing malicious code execution.

This approach eliminates the SQL Injection vulnerability and enhances the security of the click.php script.

Securing Click.php with .htaccess

To safeguard against vulnerabilities in click.php, utilizing an .htaccess file is an effective measure. This file allows for server configuration and can be used to restrict access to specific files or directories.

Creating the .htaccess File

Create a new text file using any text editor and save it with the name “.htaccess” (without the quotes). The file should be placed in the same directory as click.php.

Setting Security Directives

To prevent direct access to click.php, add the following directive to the .htaccess file:

Deny from all

This directive denies access to all users except those explicitly granted access using the following directive:

Allow from [IP Address or User Agent]

Adding Exceptions

If necessary, grant access to specific IP addresses or user agents by adding additional Allow directives. For example, to grant access to your own IP address:

Allow from 123.456.789.000

HTTP Response Code

To return a custom HTTP response code when access is denied, use the following directive:

ErrorDocument 403 /error-page.html

This directive will display the error-page.html file when a user is denied access.

Example .htaccess File:

Deny from all
Allow from 127.0.0.1
Allow from googlebot.com
ErrorDocument 403 /error-page.html

This .htaccess file will deny access to all users except those from the IP address 127.0.0.1 (local host) and the Googlebot user agent. In case of denied access, the error-page.html file will be displayed.
