A Web Application Vulnerability Scanner is a security tool designed to automatically detect common vulnerabilities in web applications, such as:
- SQL Injection (SQLi)
- Cross-Site Scripting (XSS)
- Cross-Site Request Forgery (CSRF)
- Security Misconfigurations
- Broken Authentication
The scanner performs automated penetration testing by injecting malicious payloads into user input fields and analyzing responses to identify security flaws. It is useful for developers, security analysts, and DevOps teams to secure applications before deployment.
- Automated Scanning
- Crawls web pages and identifies input fields
- Injects test payloads to detect vulnerabilities
- Logs vulnerabilities with risk levels
- SQL Injection Detection
- Tests SQLi by sending SQL-based payloads
- Detects database errors, UNION-based attacks, and blind SQLi
- Cross-Site Scripting (XSS) Detection
- Injects JavaScript payloads into input fields
- Detects execution of malicious scripts
- Security Misconfiguration Detection
- Checks for missing security headers (CSP, HSTS, etc.)
- Detects outdated software and default credentials
- Comprehensive Reporting
- Logs detected vulnerabilities with severity levels
- Generates reports in JSON or HTML format
- Provides remediation steps for each issue
- CI/CD Pipeline Integration
- Can be integrated with DevOps pipelines for continuous testing
- Supports REST API for automation
- Install Dependencies: pip install requests beautifulsoup4
- Run the Script; python scanner.py
