CVE-2019-25439Public exploitNetwork attack vector

Unauthenticated SQL injection via Referer header

Published Feb 22, 2026 · Updated Feb 22, 2026

SQL injection in NoviSmart CMS allows remote attackers to execute arbitrary SQL queries through a crafted Referer HTTP header. The root-page request path incorporates the Referer value into a database query without neutralizing SQL control syntax, enabling time-based blind extraction. No authentication or user interaction is required; the demonstrated timing oracle exposes database contents, and arbitrary queries can alter stored data.
