Open redirect vulnerability finder
Why Choose This Project?
Open redirect vulnerabilities occur when an application blindly redirects users to URLs specified in user inputs (like query parameters), potentially leading to phishing attacks, session hijacking, and reputation damage. This project detects such insecure redirect mechanisms in web applications and educates users on how to prevent them.
It's a powerful ethical hacking and auditing tool for developers, security testers, and cybersecurity learners, with practical value for bug bounty hunters and security consultants.

How It Works
-
Input URL Entry
The user enters a website or endpoint to scan for redirection vulnerabilities (e.g.,example.com?redirect=...
). -
Redirection Testing
The tool automatically injects redirection payloads. -
Response Analysis
It follows the redirection chain and checks if the response results in:-
A 3xx status code (302/301) to an external domain
-
JavaScript-based client-side redirection
-
Meta refresh tag abuse
-
-
Result Display
Vulnerable URLs and parameters are logged and displayed in a table with:-
Redirect parameter name
-
Final redirection target
-
Risk level
-
Suggested fix
-
-
Remediation Guide
Offers code snippets to secure redirection logic in various languages:-
Whitelisting allowed redirect domains
-
Using tokens or session-based verification
-
Avoiding client-side dynamic redirect paths
-
-
Admin Dashboard
View all tested URLs, status, vulnerability logs, and time/date of scans.
