Description Preview
Yab Quarx up to version 2.4.3 is vulnerable to multiple persistent cross-site scripting vulnerabilities in several user-editable fields: Blog Title, FAQ Question, Pages Title, Widgets Name, and Menus Name. These flaws arise from insufficient sanitization/escaping of user-supplied input, allowing stored scripts to persist in the application data and be rendered to other users without proper encoding. Successful exploitation could enable an attacker to execute arbitrary JavaScript in the context of other users’ sessions, with potential impacts such as session hijacking, defacement, or credential theft.
Overview
Yab Quarx versions up to 2.4.3 contain stored cross-site scripting vulnerabilities across multiple content fields including blog titles, FAQ questions, page titles, widget names, and menu names. Because the input in these fields is stored and rendered without proper escaping, attackers can inject malicious scripts that persist in the data store and execute when viewed by other users, potentially compromising user sessions and site integrity.
Remediation
- Upgrade to a fixed release or apply an official patch from the vendor that addresses the XSS vulnerabilities (verify the exact fixed version with the project maintainers). If a fixed version is unavailable, evaluate alternatives provided by the vendor.
- Implement input validation and output encoding for all user-supplied fields: Blog Title, FAQ Question, Pages Title, Widgets Name, and Menus Name. Ensure proper escaping in all output contexts (HTML body, attributes, and script contexts).
- Review and refactor code to ensure all dynamic content is escaped at render time and consider using a robust templating/escaping framework.
- Enable a strong Content Security Policy (CSP) and other web application protections (e.g., input sanitization libraries, WAF rules) to mitigate script execution.
- Conduct targeted testing with XSS payloads against the affected fields to verify that stored inputs are properly sanitized/encoded and that no scripts execute when rendered.
- Periodically audit and clean stored data that may contain previously injected payloads and establish ongoing input sanitation in future releases.
