Referer Header Redirect Vulnerability | Bug Bounty

This vulnerability occurs when a web application relies on the Referer header for redirection without proper validation, allowing attackers to manipulate it and redirect users to malicious websites.

Impact:

Phishing Attacks: Tricking users into visiting fake or malicious sites.
Malware Distribution: Redirecting users to pages hosting malicious software.
Session Hijacking: Exploiting trust to steal session tokens or sensitive data.
Loss of User Trust: Damaging the application's reputation due to unsafe redirects.
Mitigation: Validate and whitelist redirect URLs to ensure they are legitimate. Avoid using the Referer header for critical decisions.
