Enhancement of a Plant E-
commerce Web Application
• SQL Injection and XSS Prevention in PHP-
MySQL Based Systems
• Presented by: [Your Name]

2. Introduction
• • Overview of e-commerce and cybersecurity
• • Importance of securing web applications
• • Objective: Analyze vulnerabilities and
implement security solutions

3. Web System Chosen
• • Platform: Plant E-commerce Website
• • Tech Stack: PHP, MySQL
• • Features:
• - Product catalog
• - User login & registration
• - Shopping cart
• - Order tracking
• • Why this system?
• - Real-world relevance

4. SQL Injection (SQLi) - Vulnerability
• • Vulnerable Page: login.php
• • Payload Example: ' OR '1'='1
• • Impact: Bypasses authentication, data theft
• • Cause: Raw SQL queries without sanitization

5. SQL Injection - Solution
• • Fixes Implemented:
• - Use of prepared statements
• - Parameter binding
• - Input validation on server side
• • Code Snippet:
• $stmt = $conn->prepare("SELECT * FROM
users WHERE username = ? AND password
= ?");
• $stmt->bind_param("ss", $username,

6. Cross-Site Scripting (XSS) -
Vulnerability
• • Vulnerable Page: review.php
• • Payload Example:
<script>alert('XSS')</script>
• • Impact: Script execution in user browser
• • Cause: Output of raw user input without
encoding

7. XSS - Solution
• • Fixes Implemented:
• - Output escaping with htmlspecialchars()
• - Input filtering
• - Content Security Policy (CSP) headers
• • Code Snippet:
• $review = htmlspecialchars($_POST['review'],
ENT_QUOTES, 'UTF-8');
• echo "<p>$review</p>";

8. Tools & Technologies Used
• • HTML, CSS, JavaScript
• • PHP
• • MySQL
• • XAMPP (Local Server)
• • Burp Suite & OWASP ZAP (for testing)

9. Impact & Learning Outcomes

• • Captcha implementation
• • Two-Factor Authentication (2FA)
• • Role-based Access Control (RBAC)
• • Automated security scans

11. Conclusion
• • Identified and patched critical vulnerabilities
• • Improved the security of the plant e-
commerce system
• • Ensured user data safety and trust

12. Q&A
• Open floor for questions and discussions
