Password Reset Token Leak via "Host Header" and "URL" on a Third-Party Website This vulnerability occurs when a web application improperly handles password reset tokens, exposing them to attackers through: Host Header Manipulation: Some applications generate password reset links using the Host header provided in the HTTP request. If an attacker manipulates the Host header and the application blindly trusts it, the reset link might include a malicious domain controlled by the attacker. The victim, upon receiving and clicking the link, submits their reset token to the attacker's domain, allowing account takeover. URL Exposure on a Third-Party Website: If an application leaks password reset URLs in referer headers, logs, or third-party integrations, an attacker monitoring those locations can capture the reset token. Example: If the reset link is included in a URL parameter that gets logged or shared with external services (e.g., analytics tools, chatbots), attackers might retrieve it and reset the victim’s password. Impact Allows an attacker to reset passwords of victim accounts. Leads to full account takeover. Can be exploited remotely if combined with phishing or session hijacking. Mitigation ✅ Use absolute, hardcoded URLs for password reset links instead of relying on the Host header. ✅ Implement a strict Content Security Policy (CSP) to prevent token exposure in third-party requests. ✅ Avoid logging sensitive URLs and tokens. ✅ Use Referer-Policy: no-referrer to prevent leaks in referer headers. ✅ Ensure password reset tokens are short-lived and single-use. #ethicalhacking #bugbountyhunting #coding #cybersecurity #computersecurity
