Attack-Flow Graph

Executive Summary

This is an Unauthenticated Cross Site Scripting (XSS) vulnerability found in Quiz And Survey Master plugin versions up to and including 11.2.6. XSS allows attackers to inject malicious scripts into web pages viewed by other users without needing authentication.

Detection Guidance

To detect this XSS vulnerability in Quiz And Survey Master <= 11.2.6, inspect web forms or survey inputs for unsanitized user-supplied data. Check for reflected or stored XSS by submitting test payloads like <script>alert(1)</script> in input fields and observing if the script executes. Review server responses for echoed input without proper encoding.

Impact Analysis

An attacker could exploit this to steal user sessions, redirect users to malicious sites, or deface web pages. Since no authentication is required, any visitor to a vulnerable site could be affected.

Compliance Impact

This vulnerability could lead to data breaches by allowing attackers to access sensitive user data, violating GDPR and HIPAA requirements for data protection and confidentiality.

Mitigation Strategies

Immediately update Quiz And Survey Master to the latest version beyond 11.2.6 to patch the XSS flaw. If updating is not possible, disable the plugin temporarily or restrict access to untrusted users. Implement input validation and output encoding on all user-supplied data to prevent XSS attacks.
