Build a Web Application Vulnerability Scanner

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 It simulates attacks like SQL injection and cross-site scripting, checks for outdated libraries, and inspects HTTP headers and cookies.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.

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.
