ETQ Reliance - Reflected XSS via SQLConverterServlet

id: CVE-2025-34141

info:
  name: ETQ Reliance - Reflected XSS via SQLConverterServlet
  author: slcyber,pdresearch
  severity: medium
  description: |
    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.
  remediation: |
    Upgrade to ETQ Reliance version SE.2025.1 or later where the SQLConverterServlet has been disabled.
