Informational
Default Solution Advices
To minimize risks, there are a few things should do.
- If you do not use related service then stop it. Do not increase your attack surface. Stoping unnecessary services is one of the best practices and huge step in hardening operation systems. For example if port 21 open for ftp and you do not using it, stop ftp service.
- You should restrict access. Use either a firewall to allow specific IP addresses for your port if you can or change your service settings to make accessible only from localhost.
- Make sure your softwares are up to date. Do not miss any security patches.
- Use strong password if your services use an authentication mechanism (like ssh, ftp, rdp). Whole internet are scanning by attackers to detect weak passwords.

Online Generic SQL Injection Vulnerability Scanner
Detect SQL Injection vulnerabilities in your web applications
Default Solution Advices
You can apply the following methods to avoid SQL Injection vulnerability.
-
Where SQL queries are made by taking input from the user (for dynamic queries), parameter binding (also known as prepared statements) should be applied. Stored procedures can be preferred.
-
User inputs should never be trusted, all inputs should be processed after filtering. While filtering, instead of blocking individual characters (black-listing), a certain character string should be allowed, and the remaining characters should be blocked (white-listing).
-
While making a database connection, the principle of least privileges should be applied. The connection should be provided by giving limited access to the necessary places. No connection to the database should be made with authorized users such as "root", "SA".
-
Critical data should be encrypted in the database, not in plain text.
-
A custom error page should be created and displayed at the time of error so that the database information is not exposed during an exception that may occur in the web application.
AI Based Solutions
The scan results indicate that the "Online Generic SQL Injection Vulnerability Scanner" has detected vulnerabilities associated with SQL Injection in your web application. The specific types of SQL Injection vulnerabilities identified include:
-
Boolean-based Blind SQL Injection: The application appears to execute SQL queries with a vulnerable parameter (
test), allowing attackers to infer database information based on the application's output of true or false conditions.
-
Time-based Blind SQL Injection: By leveraging the database's ability to perform time delays (e.g., using the
SLEEP function in MySQL), an attacker can exploit this to infer data based on the response time of the application.
-
UNION-based SQL Injection: The vulnerability allows injecting UNION queries to extract data from the database by combining results from multiple SELECT statements.
Tailored Solution for PHP Applications Using PDO:
Given that your web application likely uses PHP and interacts with a database, it's important to implement proper security measures to prevent SQL Injection attacks. Here's a customized solution focusing on PDO (PHP Data Objects):
1. Use Prepared Statements with Parameterized Queries:
-
Always use prepared statements and parameterized queries instead of directly including user-provided input in your SQL queries.
// Example of using prepared statements with PDO
$stmt = $pdo->prepare("SELECT * FROM users WHERE username = :username AND email = :email");
$stmt->execute(['username' => $usernameInput, 'email' => $emailInput]);
- Prepared statements ensure that user inputs are treated as data instead of executable code, thus preventing SQL Injection.
2. Use PDO for Database Access:
-
PDO provides a secure and uniform way to manage different types of databases while encouraging secure coding practices.
try {
$pdo = new PDO('mysql:host=your_host;dbname=your_db', 'username', 'password');
$pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
} catch (PDOException $e) {
echo "Connection failed: " . $e->getMessage();
}
3. Harden Your Database:
- Ensure that your application's database user has the least privilege necessary to perform its tasks.
- Keep your database server and related libraries updated to protect against known vulnerabilities.
4. Employ Web Application Firewalls (WAF):
- Use a Web Application Firewall to detect and block SQL Injection attempts before they reach your application.
5. Input Validation and Sanitization:
- Always validate and sanitize user inputs on both client and server sides. Define expected input types and constraints.
// Example of input validation
$emailInput = filter_var($emailInput, FILTER_VALIDATE_EMAIL);
Following these recommendations will help fortify your web application against SQL Injection vulnerabilities and improve overall security. Always perform security testing regularly to ensure that new threats can be mitigated promptly.

- Keep your database server and related libraries updated to protect against known vulnerabilities.
4. Employ Web Application Firewalls (WAF):
- Use a Web Application Firewall to detect and block SQL Injection attempts before they reach your application.
5. Input Validation and Sanitization:
- Always validate and sanitize user inputs on both client and server sides. Define expected input types and constraints.
// Example of input validation
$emailInput = filter_var($emailInput, FILTER_VALIDATE_EMAIL);
Following these recommendations will help fortify your web application against SQL Injection vulnerabilities and improve overall security. Always perform security testing regularly to ensure that new threats can be mitigated promptly.
-
Boolean-based Blind SQL Injection: The application appears to execute SQL queries with a vulnerable parameter (
test), allowing attackers to infer database information based on the application's output of true or false conditions. -
Time-based Blind SQL Injection: By leveraging the database's ability to perform time delays (e.g., using the
SLEEPfunction in MySQL), an attacker can exploit this to infer data based on the response time of the application. - UNION-based SQL Injection: The vulnerability allows injecting UNION queries to extract data from the database by combining results from multiple SELECT statements.
Tailored Solution for PHP Applications Using PDO:
Given that your web application likely uses PHP and interacts with a database, it's important to implement proper security measures to prevent SQL Injection attacks. Here's a customized solution focusing on PDO (PHP Data Objects):-
1. Use Prepared Statements with Parameterized Queries:
- Always use prepared statements and parameterized queries instead of directly including user-provided input in your SQL queries.
- Prepared statements ensure that user inputs are treated as data instead of executable code, thus preventing SQL Injection.
- PDO provides a secure and uniform way to manage different types of databases while encouraging secure coding practices.
- Ensure that your application's database user has the least privilege necessary to perform its tasks.
- Keep your database server and related libraries updated to protect against known vulnerabilities.
- Use a Web Application Firewall to detect and block SQL Injection attempts before they reach your application.
- Always validate and sanitize user inputs on both client and server sides. Define expected input types and constraints.
// Example of using prepared statements with PDO
$stmt = $pdo->prepare("SELECT * FROM users WHERE username = :username AND email = :email");
$stmt->execute(['username' => $usernameInput, 'email' => $emailInput]);
2. Use PDO for Database Access:
try {
$pdo = new PDO('mysql:host=your_host;dbname=your_db', 'username', 'password');
$pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
} catch (PDOException $e) {
echo "Connection failed: " . $e->getMessage();
}
