CVE-2020-37112Public exploitNetwork attack vector

Database disclosure via unneutralized agenda month parameter

Published Feb 3, 2026 · Updated Feb 3, 2026

SQL injection in GUnet Open eClass 1.7.3 allows remote authenticated users to extract database contents through the agenda month parameter. The agenda module's myagenda.php endpoint incorporates the month GET value into a MySQL query without neutralizing SQL syntax. A student account is sufficient, and error-based payloads can expose all database content without reported service interruption.
