Build a Web Application Vulnerability Scanner
Develop a tool that scans web applications for common vulnerabilities like SQL injection, XSS, and security misconfigurations — a powerful cybersecurity utility for ethical hackers and developers.Modern web apps often suffer from security flaws that leave them open to attacks. Manual testing is time-consuming and error-prone. An automated vulnerability scanner can quickly identify flaws like injection attacks, broken authentication, and insecure headers — helping developers and security teams take fast action.
This scanner takes a target URL and analyzes the web application for common vulnerabilities. It simulates attacks like SQL injection and cross-site scripting, checks for outdated libraries, and inspects HTTP headers and cookies. The results are summarized in a detailed report for remediation.
SQL Injection & XSS Detection
Send payloads to detect potential input validation flaws in forms and URL parameters.
Security Header Analysis
Check for missing or misconfigured headers like CSP, HSTS, X-Frame-Options.
Cookie Security Inspection
Analyze cookies for secure, HttpOnly, and SameSite attributes.
PDF Vulnerability Report
Generate a downloadable report listing all vulnerabilities and recommended fixes.
Users input a web application's base URL. The tool crawls pages, identifies inputs and scripts, and runs simulated attack payloads against them. It then analyzes the server’s responses and behavior to detect vulnerabilities and summarizes them for reporting.
- Input a target web application's URL.
- Tool crawls and maps the site structure, detecting input fields and forms.
- Runs payloads to test for vulnerabilities like SQL injection or XSS.
- Scans HTTP headers and cookies for security best practices.
- Displays results in a dashboard or exports a report as PDF/CSV.
Frontend
React.js or Next.js for the dashboard UI and scan submission form.
Backend
Python Flask or FastAPI to handle scanning logic and vulnerability analysis.
Scanning Engine
Use libraries like Requests, BeautifulSoup, or Selenium for crawling and payload injection.
Reporting
ReportLab or WeasyPrint to generate professional PDF reports.
1. Input & Crawler Setup
Build input form for URL and crawler to scan internal pages and forms.
2. Simulate Attacks
Send attack payloads to test for injection, XSS, and header misconfigurations.
3. Analyze and Categorize Vulnerabilities
Parse server responses and categorize risks based on severity.
4. Dashboard UI & Reports
Display results in an admin panel and enable exporting reports.
5. Optional Authentication Scanner
Add support to scan authenticated sections using login credentials or session cookies.
Scan and Secure Web Applications Automatically
Build a tool that empowers developers and security professionals to proactively find and fix vulnerabilities in web applications.
