Open Redirect

Description

Open redirect vulnerabilities occur when a web application accepts user-controlled input that specifies a link to an external site and uses that link in a redirect. This can be used for phishing attacks or to bypass security controls.

Common Attack Vectors

• URL parameters (redirect, url, return, next)
• Login/logout redirect parameters
• OAuth callback URLs
• Error page redirects

Testing Approach

Submit external URLs in redirect parameters to test if the application redirects to arbitrary external sites.
