CVE-2021-47902Public exploitNetwork attack vector

Database disclosure via injectable search parameter

Published Jan 27, 2026 · Updated Jan 27, 2026

SQL injection in Aftabgardan Testa Online Test Management System 3.4.7 allows remote attackers to read database data through the q search parameter. Public evidence does not identify the query-building function, but the demonstrated POST places q into a UNION-selectable database query without effective neutralization. No account or user interaction is required, and successful requests disclose database contents and permit limited query-driven modification.
