Executive Summary

This is a reflected Cross-Site Scripting (XSS) vulnerability in the Auktion NG auction software. It exists in the /forgotpasswd.html file where the email parameter is not properly encoded. Attackers can inject malicious HTML or JavaScript code via this parameter. When a victim interacts with the page, such as hovering over the email input field, the injected script executes within the trusted domain auction.venta24.de.

Detection Guidance

To detect this reflected XSS vulnerability, test the /forgotpasswd.html endpoint by sending a crafted request with a malicious email parameter. Use tools like curl or browser developer tools to send a request with an email value containing a script tag, such as email=<script>alert(1)</script>. Monitor the response for script execution or unexpected HTML rendering.

Impact Analysis

This vulnerability could allow attackers to perform phishing attacks, manipulate the user interface, or execute unauthorized actions through the victim's browser session. Attackers might steal session cookies, redirect users to malicious sites, or trick users into revealing sensitive information.

Compliance Impact

This vulnerability could lead to data breaches, compromising personal or sensitive data. Under GDPR, this may result in fines due to inadequate protection of user data. For HIPAA, it could violate safeguards for protected health information if such data is exposed.

Mitigation Strategies

Immediately apply input validation to sanitize the email parameter in /forgotpasswd.html. Implement context-aware output encoding to prevent script injection. Deploy a Content Security Policy (CSP) to restrict inline scripts. Regularly audit the application for similar issues and ensure secure template escaping is used.
