Attack-Flow Graph

Executive Summary

LimeSurvey Community Edition 7.0.5 has an authenticated stored cross-site scripting (XSS) vulnerability in the replacement-fields dialog of the administrative question editor. This means an attacker with access can inject malicious scripts that are stored on the server and executed when other users view the affected content.

Detection Guidance

To detect this vulnerability, inspect LimeSurvey instances running version 7.0.5 for unauthorized JavaScript in replacement-fields dialogs within the administrative question editor. Check browser console logs for suspicious scripts during admin operations.

Impact Analysis

If exploited, this vulnerability could allow attackers to steal user sessions, perform actions on behalf of users, or deface the application. Users with administrative access are particularly at risk as the vulnerability resides in the question editor used by admins.

Compliance Impact

This vulnerability could lead to unauthorized access to sensitive data, violating GDPR's data protection principles and HIPAA's security requirements. It may result in data breaches, unauthorized disclosure, or loss of data integrity, potentially leading to legal penalties and compliance failures.

Mitigation Strategies

Upgrade LimeSurvey to a version later than 7.0.5. If immediate upgrade is not possible, restrict access to the administrative interface and review stored scripts in the replacement-fields dialog for malicious content.
