The “Flower.php” script is an example
of a vulnerable PHP file that contains a SQL injection vulnerability. Here’s an example of the vulnerable code:
<?php
// Connect to the database
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "mydatabase";
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
// Get the user input from the URL parameter 'name'
$name = $_GET['name'];
// SQL query to select data from the 'flowers' table
$sql = "SELECT * FROM flowers WHERE name LIKE '%$name%'";
// Execute the query
$result = $conn->query($sql);
// Check if the query returned any results
if ($result->num_rows > 0) {
// Output data of each row
while($row = $result->fetch_assoc()) {
echo $row["name"] . " - " . $row["price"] . "<br>";
}
} else {
echo "0 results";
}
$conn->close();
?>
In this example, the vulnerable code is the use of user-input data ($name) directly in the SQL query string without proper sanitization. This allows an attacker to inject malicious SQL code, which can lead to unauthorized access, data modification, or even complete database takeover.
For instance, if an attacker requests the script
with a URL like flower.php?name=' OR 1=1 --, the SQL query would become:
SELECT * FROM flowers WHERE name LIKE '%'' OR 1=1 -- %'
The -- comment at the end effectively makes the rest of the query string a comment, allowing the query to return all rows from the flowers table. This demonstrates a classic SQL injection vulnerability. It’s crucial to always validate and sanitize user-input data to prevent such attacks. The PHP community recommends using prepared statements with parameterized queries to mitigate SQL injection risks.
Protecting Against ‘flower.php’ with .htaccess
Websites face various threats. One is ‘flower.php.’ It often contains malicious code. Examples include ‘Exploited system file,’ ‘eval(base64_decode,” and ‘preg_replace with /e modifier.’ These can lead to ‘Redirect Malware.’ Using .htaccess can help. It enhances security.
First, understand .htaccess. It’s a configuration file. It controls web server behavior. Place it in your root directory. It can block specific files. This includes ‘flower.php.’ Blocking it prevents exploitation. Next, add rules to .htaccess. Use the ‘Deny from all’ directive. It blocks access to ‘flower.php.’ Add this line to your file: Deny from all. This prevents direct access. It stops malicious users.
Additionally, use ‘RewriteRule.’ It redirects requests. Add this rule: RewriteRule ^flower\.php$ - [F,L]. This returns a 403 Forbidden error. It effectively blocks ‘flower.php.’ No one can access it. Furthermore, disable PHP execution. Use ‘Files’ directive. Add this code: <Files "flower.php"> ForceType application/octet-stream Header set Content-Disposition "attachment" </Files>. This forces file download. It prevents PHP execution.
Finally, monitor your site. Use logs to track access.
Regularly update .htaccess. Stay informed about new threats. This ensures ongoing protection. Your site remains secure.
Here is the example .htaccess code:
# Block direct access to flower.php
